"newton waterproofing systems"

Leafy Windlesham in Surrey was the location for this 5-bedroom, £15,000,000 mansion by Searchfield Homes, complete with a 4-metre deep basement containing a swimming pool and spa pool, all of which needed to be protected from water ingress and ground gases.

Installing a comprehensive internal and external structural waterproofing solution to prevent the ingress of ground water.

The King Edward VII Galleries is a Grade 1 listed structure and part of the iconic British Museum complex in London.Constructed between 1907 and 1914, the building sits above a series of tunnels and ventilation shafts, which serve to supply air to the gallery via an external ventilation unit.Due to water ingress in the tunnels, there was serious concern as to the quality of air supplied to the gallery, and the impact that this might have on the artefacts kept there.

Built in 1855 as an Elizabethan School for local children, the historic and landmark Castle Club has also been a children’s hospital, youth club and private residence in its long history.Since being acquired by property developers Thackeray Group however, the Grade II Listed building is now to be converted and extended as a specialist care home.The work includes not only the restoration of the historic gothic structure, but also the building of a modern four-storey extension to the rear, including a 5,000-square-foot basement extension.

“Venesta's products are great value and the staff are helpful and committed; their full height cubicles are ideal for areas where privacy is essential. Venesta met the challenge of matching their cubicles to the Isaac Newton colours to fit in with the theme of the building” - Akos Juhasz, Architect The unisex washroom had to be as secure and private as possible for students whilst looking bright and inviting to use with easy supervision of the communal areas. "(Unity's) flush-fronted design and full height doors, allowing for total privacy, made it the perfect choice."

The Newton Station is an important architectural project with contemporary character located in Adelaide. Various surfaces and details of the Atlas Concorde grey porcelain range were used in the project, which is an excellent example of public architecture.Atlas Concorde porcelain tiles are characterised by top quality technical performance and aesthetics; it is perfect for high traffic architectural projects. For the Newton Station project the Trust series was used, porcelain tiles with a matt finish that are the perfect solution for any kind of outdoor floors and walls.The outdoor tiles used in the Australian station give the project a contemporary feel and perfectly integrate with the surrounding urban environment. 

When it comes to residential, commercial or any structure below ground, waterproofing is a critical component within the construction process for protecting and preserving a building. A poorly designed or installed waterproofing solution can fail leading to significant implications on the structure itself.Delta Registered Installers, Abtech (UK) Ltd were called upon to give assistance on a particularly technically complicated project where approaches to waterproofing design and installation had been incorporated, however the system had failed. For a great remedial waterproofing outcome, seek assistance from an experienced waterproofing company to inspect your site and carry out the remedial work.The property when built had a Type C, cavity drain membrane systems incorporated (not a Delta System), however there was no basement drainage incorporated into the design to manage water ingress.In principle a Type C, drainage system is a water management system. The Type C system is used to control water ingress once it has penetrated the structure.  Moisture or running water travel behind the Type C membrane within a controlled drainage system. A Type C System isn’t classified as a barrier but provides protection by means of water management. For a Type System to be successful a suitable drainage system is required to collect and discharge water ingress to a suitable and safe evacuation point (either by natural forces or a mechanical pump system).When correctly installed, groundwater drainage channels effectively relieve hydrostatic water pressure in the below ground structure. They are installed below flooring membranes at the floor/wall junction.

The scope of the works was to design, specify and install a suitable waterproofing solution to 2 large properties engineered from ICF construction which required waterproofing. Areas where attention from a skilled specialist were required, was to the rear and two side walls which were earth/ground retaining.When specifying a suitable waterproofing solution, consideration to the final use of the building, designing a system to be maintainable and repairable along with a deep understanding of BS 8102:2009 is essential in ensuring project success.From a waterproofing design perspective, we use three grades to define waterproofing systems.These 3 grades are:Grade 1 – Some water seepage and damp are tolerable depending on the intended useGrade 2 – No water penetration is acceptableGrade 3 – No dampness or water penetration is acceptableIn existing basements and new build properties which will be habitable, Grade 3, is always required.

Waterproofing and damp proofing specialists, Severn Damp & Timber Preservation, installed a range of Triton Systems’ waterproofing materials to deal with water ingress around two skylights, formed within the concrete roof deck over a basement that extended into the garden of a domestic property. 

Triton Systems approved contractor, British Damp Proofing, installed products supplied by Triton Systems to waterproof two lift shafts in a development of 25 dwellings. Triton Bentonite Membrane was used to waterproof the lift slab base and kicker, which were poured using concrete made waterproof with Triton TT Admix. Triton's Adcor waterbar was then installed on to the kicker.

Waterproofing design is a key and critical component for successful construction of below ground structures. Whether it’s a completely new build or making smaller changes to an existing property, waterproofing design should never be overlooked.Waterproofing might account for just a small fraction of a building’s total cost, but waterproofing defects can result in catastrophic consequences. When waterproofing fails, the implications are significant.Delta’s MD, Kevin Dodds was approached to offer advice and guidance on a failed waterproofing system.The existing structure had an impressive 5-level basement which houses: kitchens, food storage and food preparation areas, spa, plant rooms and accommodation. Near to a large river, the site sited well within the water table. The original waterproofing system was based on the secant piled walls and a block wall internally to provide a basic drained protection system with drainage holes at various points to drain to various levels.Over time, the third floor had become completely saturated with all levels of the basement experiencing water ingress in varying levels from damp patches to significant “jets” of water and flows of water through the secant piles.With remediation waterproofing design strategies, it may take some time to specify a suitable system. It is important that investigations are thoroughly carried out by individuals with the capability of diagnosing the defect, assessing the extent of that defect, and recommending a suitable corrective measure.

The scope of the project was to facilitate a waterproofing solution for a substantial brick built detached property with a large 3 elevation basement situated at the bottom of a steep sloping driveway. The basement when constructed had 1 form of external waterproofing incorporated during the build stage, however the system required a second form of internal waterproofing due to the location of the structure and high-water table, capable of protecting the luxurious basement from unwanted water ingress.The property’s driveway significantly slopes from street level to the front elevation of the property requiring a specialist waterproofing system to protect the structure.Working in conjunction with the homeowner, Timberwise’s CSSW qualified waterproofing surveyors specified a Delta Type C (Drained) Protection waterproofing system to provide the necessary Grade 3 (habitable environment) to enable to homeowner to fully utilise their basement space. For Grade 3 habitable environments, two types of waterproofing may be required.A Waterproofing Designer’s philosophy defines what they wish to accomplish in the design of their waterproofing system and which principles they will use to do so. Identifying a robust and suitable design philosophy is an important aspect when designing a continuous system, as this will not only directly impact in how users install the system but also in future maintenance which will directly impact on the property owner.

The extended structure of the Isaac Newton Building in Lincoln houses the Schools of Computer Science, Engineering, Mathematics and Physics which offer unrivalled scientific and engineering facilities for students. This includes new seminar rooms and computer labs in addition to state-of-the-art technology and research rooms, complete with a semi-anechoic chamber.Playing a significant role in creating the curved appearance of the building was our visible grid aluminium curtain walling. This durable and versatile system can be applied to flat or faceted facades and is available in a choice of glazing gaskets and larger glass sizes. Aluminium windows were also installed throughout the building for modern design and complete weather protection.

Triton approved contractors, Advance Property Preservation, installed a Type C (BS 8102 2009) structural waterproofing system in the construction of a luxury domestic basement. The property is a late Victorian, six-bedroomed detached home in Notting Hill, London.

The purpose:Taylor Wimpey’s Eclipse development was the final phase of the large-scale modernisation and renewal strategy for the London Borough of Walthamstow Forest, known as The Blackhorse Lane Action Plan. Eclipse would offer affordable social and private housing via 500 homes in two six-storey apartment blocks.To help satisfy one of the Plan’s objectives- “to ensure new developments incorporate the highest levels of sustainable design and their impact on climate change is minimised”- we installed green roofs on both blocks. As it was the final development phase, space was limited; time was also an influencing factor in facilitating the tight build programme,avoiding delays, and enabling the client to deliver much-needed new homes.Our solutionTo enable fulfilment of the brief, we recommended our HM-40 Paratech Hot Melt Roofing System as the inverted waterproofing base for the green roof. A fully-bonded system, HM-40 is a robust, durable, and highly flexible monolithic, self-healing hot-melt waterproofing system for protected roofs, green roofs, terraces, and podium decks with a 40-year durability statement. In addition, it is firerated for unrestricted use when covered with a green or ballast roof.Unlike other hot melt systems that use fleeces, the Paratech system incorporates a reinforcement mesh: this allows the system to be rolled out, making waterproofing installation faster, thereby enabling the contractor to lay the top roofing layer of artificial grass and landscaped green roofs. Unfortunately, an on-site compound to store the roofing components was unavailable. We worked closely with T&T Roofing and Taylor Wimpey to ensure deliveries arrived in build sequence for immediate use, but without adversely impacting residents who had already moved into their newhomes.“The features of the flat roof system provided a seamless, issue-free roof installation, with rapid installation time causing minimal disruption. Langley’s technical team was always on hand to provide assistance when necessary, working collaboratively to guarantee a consistent and highquality installation.”

Delta’s Technical Team along with Delta Registered Installers Marsden Damp Services were approached by the main contractor Wilmott Dixon to give assistance on designing a robust waterproofing solution. Working in collaboration with the architects and project team, this team of waterproofing experts were easily able to offer a simplistic and practical approach.The project was split into 2 phases with Phase 1 waterproofing the existing stage and orchestra pit and Phase 2, the seating and ancillary rooms which all required the installation of a Type C waterproofing system to ensure a Grade 3 habitable environment was created.

Sunshine Gym have provided a brand new outdoor gym at Newton Primary School in Derbyshire.Newton Primary School decided upon the Primary School Outdoor Fitness Package which provided a pre-determined mixture of equipment specially selected by our experts to encourage fitness within primary schools. The equipment can be used by eight pupils simultaneously. Inclusive of both multi and single user equipment this package can be used as a gentle cardiovascular workout. It features two pieces of multi-user equipment, and these ‘dual’ units promote social interaction whilst still allowing the pupils to exercise at their own pace.The equipment was installed on grass saver matting. This additional safety surface, over time, will encourage the grass to grow through and be mowed. Thus allowing it blend with the natural surroundings.This specific outdoor fitness package is to be used by children under 140cm. This makes it perfect for the KS1 & KS2 pupils, and they can use it for small classes for PE pupils or even as an after school fitness initiative.

Delta Registered Installers, Premier Preservations, were approached to offer a waterproofing design and system to a basement, to ensure the vaults – located under the entire footprint of the property were protected from water ingress.

The Scope of the project was to provide a structural waterproofing solution to a private dwelling with new build extension.The property, situated on a sloping site gave the opportunity for the waterproof design to utilise the properties environment to allow for natural discharge of any potential water ingress.The property was detached and retaining to the front and side elevations where the retaining ground slopes down and away from the property to a garden that continues to slope down to a small stream. The retaining walls on either elevation rise at their highest point to approximately 1500mm above the internal floor level.The internal walls of the property were original brick to the front and new cavity built concrete block. The floor to what was the original house is of solid concrete construction joining on to a newer block and beam floor construction.When designing the most appropriate waterproofing system to any given situation, various design factors require addressing such as (but not limited to), final use of the building, the grade of waterproofing requirement under the British Standard, structural considerations based on the form of construction and in some cases, satisfying the requirements of building warranty providers.

Vaults are a common feature of 18th and 19th century buildings in Bath. Originally built to support the cobbled streets above and were a constructional response to the precipitous topography that surrounds Bath, in order to provide a level site. Many of the vaults within historic Bath suffer with water ingress and damp related problems. Incorporating best practice guidance - Type C Waterproofing Systems (BS 8102: 2009) a Type C System was used to keep this historic vault watertight and dry.

IKO Polimar FCS is a high performance cold applied, two part, fast curing waterproofing system was a perfect solution for this project as it cured within 20 minutes. Also, being a self-levelling and slip resistant product, it enabled residents to come and go within minutes of it being applied.

The White Collar Factory will be a mixed-use are of workspace, residential and retail, designed by architects, AHMM. The development, sited on London's City Road, comprises a new 16-storey office tower, a new public square and refurbished existing buildings to the rear. The new 2-storey basement has been waterproofed using a Type C system applied internally, to provide drained protection in accordance with BS 8102: 2009. The waterproofing was supplied by Triton Systems.

Emma House, Romford, a residential apartment block built in 2007, needed a new waterproof membrane for the entire roof area after the single ply membrane, installed just 10 years earlier, had failed. The specification by our clients asked for a cold applied system to be used during the refurbishment to minimise disruption to residents, while providing a permanent waterproofing solution.The ChallengeCore samples taken of the roof build-up showed there had been extensive water penetration which required urgent remedial action. Impossible to repair, the complete roof system had to be stripped back to the roof deck by Proteus Waterproofing’s approved contractor. The approved contractor installed a new Proteus Pro-System® BUR (built up roof system) incorporating Proteus Pro-Therm insulation, to provide a new seamless roof – an area of some 150 square metres – offering a 20 year guarantee.Why Proteus Pro-System® was specifiedProteus Pro-System® was installed using no heat, providing a seamless waterproofing membrane on completion. Proteus Pro-System® is a high performance, seamless and cold-applied waterproofing membrane for flat and pitched roofs. It cures to provide completely seamless waterproof protection and has excellent thermal and UV stability, making it suitable for use in all climates.Proteus Pro-System® does not brittle, deteriorate or discolour with age. It uses atmospheric moisture to trigger its cure process and unlike conventional polyurethane systems can cure under water, without gassing or foaming. It also becomes resistant to rain damage and may therefore be applied in relatively poor weather, without any subsequent loss of performance or durability – making it ideal for Emma House.About Emma HouseEmma House consists of 14 one-bedroom and 19 two-bedroom apartments just minutes away from the centre of the market town of Romford, which offers shops, services and a wealth of bars and restaurants. When first built in 2010, Emma House offered young professionals an opportunity for affordable housing close to London and has remained at the forefront of the property market in Romford ever since.

Our purposeAs one of the UK’s leading housing associations, the Guinness Partnership prides itself on providing high quality homes that meet or exceed current Standards. It is therefore committed to a continuous programme of maintenance and asset management across its 60,000 homes estate.As part of that process, the 13-storey 1980s-built Waverley Court in Crewe was due for refurbishment, including new windows and heating for the 95 flats therein. An initial survey highlighted that the 1200m2 roof was failing and in need of upgrade to maintain its weathertightness.Our in-depth roof report also identified that the insulation was below current standards. Safety on the roof for maintenance was also an issue: the existing handrail was originally erected as a temporary fixture, penetrating the waterproofing and providing inadequate rooftop security for working at height.Our solutionThe existing waterproofing had perished beyond useability. We advised complete strip of the existing back to the concrete deck, and building up a new thermally-efficient roof to meet current standards required under the Part L of current Building Regulations.Our TA-25 W Flat Roofing System for warm roofs was installed by Approved Contractor Everlast as sub-contractor to the principle contractor, Wates. To address the poor falls on the roof, the insulation was tapered to the perimeter. We achieved an overall roof U value of 0.17W/m2K, exceeding the current Regulatory requirement of 0.18W/m2K. In line with Safe2Torch guidelines, our self-adhesive system was used to detail around roof penetrations for extractor fans and similar plant.We highlighted and designed bridging details to maintain the fire integrity around compartment walls to comply with Part B3 of Building Regulations.We designed a new, permanent and safe handrail system. This is fixed to the brick façade of Waverley Court, avoiding any penetration of the roof fabric and thus maintaining its integrity and watertightness, whilst minimising maintenance requirements.“Langley’s expertise and attention to detail has enabled us to deliver on our ambition of providing homes that people want to live in. Langley’s performance has helped us provide a dry, warm, safe living environment that exceeds current Regulatory requirement. The independent insurance-backed guarantee covering design, materials and workmanship adds value to our long-term estate asset management.”

Two/three stage underpinning. Internal steel staircase frame. Piling. Mass excavation of spoil. Construction of rear extension. Below slab drainage. Cavity drain Waterproofing. Insulation and screed. Swimming pool shell within lower level basement.

This large new-build structure required to be waterproofed to meet BS 8102:2009, the British Standard for the Protection of Structures against Water from the Ground requirements. As it is not possible to determine the amount of potential water pressure surrounding the structure, BS 8102:2009 states the waterproofing designer should expect a head of water against the structure at some stage during the structure’s service life.

The London Olympics Aquatics Centre has been given a watertight seal with the application of Preprufe® waterproofing membrane from GCP Applied Technologies. GCP was able to meet the architects’ full requirements combining the Preprufe® comprehensive waterproofing and gas protection with a range of fully compatible pre-applied and post-applied membrane systems. The specification of the Preprufe® waterproofing system has ensured that after the Olympic games, the facility will continue to benefit from long term waterproofing and gas protection performance befitting of the Olympics Legacy.

The existing waterproofing had failed due to a previous poor installation, the result of which saturated the insulation below the exterior roofing. New high performance solutions were specified that included a range of IKO roofing waterproofing systems to protect both the flat and pitched roofing areas of the building. IKOslate, a robust and durable tile was specified for the pitched roof due to vandalism and the fragility of the current system, whereas a tapered scheme was required for the flat roofing - IKO Ultra Prevent alongside a cold applied liquid solution (IKO Polimar) for the more intricate details.

Delta Registered Installers, Bensleys provided a waterproofing solution on an iconic Brighton structure.Steeped in history and thought to be built on the original Brill Baths site, sits Clarendon Mansions. This large, detached structure is thought to have been built in 1870 by Charles Brill during the Brighton boom.The four-storey building facing Brighton’s famous sea front, was originally constructed as a hotel.Numerous refurbishments over subsequent periods of time, saw the structure move from a hotel to a public house, with the basement area being unoccupied for nearly a decade.The basement area boasts large, vaulted areas to the south and west elevation, with the south-side possibly being part of the original Bath structure.Bensleys were instructed by the main contractor, Pilbeam Construction on behalf of Evolution Architects, to help design, specify and install the waterproofing system.There’s no one-size-fits-all when it comes to waterproofing design. With the basement suffering from water penetration, Bensleys worked with the design team at an early stage of the project to ensure the right approach be taken, which included multiple factors such as: customer requirements, standards, robustness, cost, resources, time, skill required, safety and expectations of ground water which all translated into a design solution.

The Proteus Waterproofing roof survey carried out found the existing flat roof system to be saturated. The existing roof build-up needed to be stripped back to the roof deck, with the main challenge of the roof refurbishment being the low up-stand heights available to the penthouses.The project required a flat roof system manufacturer involved at the initial roof survey and specification design stage, followed by the manufacturers technical back-up to assist with unforeseen and unexpected situations to ensure a successful installation of the new roof systems.High Performance WaterproofingThe terrace roofs above hated spaces demanded a waterproofing system with BBA certification. The fully bonded and seamless Pro- System® Plus was selected for its high performance and low odour, in conjunction with Proteus Pro-Therm Insulation to improve the roofs thermal performance and reduce the existing condensation risk.The flat roofs that were not above heated spaces required Proteus Pro-System® Plus low odour, seamless waterproofing overlay. Proteus Waterproofing worked closely with the Client and the Proteus Approved Contractor, which also acted as the Main Contractor, to ensure the installation complied with the specification design.Health & SafetySafety on construction sites is always of the utmost importance, as well as keeping disruptions to other trades to a minimum. Proteus Pro-System® Plus was selected for its high performance, low odour, phased cold installation and seamless waterproofing.Long Term Performance​Proteus Pro-System® Plus creates an elastomeric, seamless, cold applied waterproofing membrane. The Proteus Pro-System® Plus system can include warm roof insulation. The membrane does not become brittle with age, is BBA Certified with a durability statement of at least 30 years.

The scope of this ambitious project was to restore and transform an abandoned Neo-Gothic Cemetery Keeper’s Lodge with adjoining public facility into a luxurious mansion in just 12 months.  Works included demolishing the adjoining public facility to enable the construction of a new basement.The proposed new build construction would be a luxury ground floor extension which would run the footprint of the redundant public facility to offer a 4,000 square foot subterrain space with key features such as 13-meter swimming pool, 2 additional bedrooms, a tv games room and office space.Simon Gill Architect designed the ambitious project and was appointed as Project Manager.Delta Registered Installers 5 Star Basements were employed to undertake both dig out and installation of the structural waterproofing with Delta’s Technical Waterproofing Consultant, Paul Callaghan representing Delta. This approach at the design stage, allowed Paul to attend design team meetings and to ensure all criteria’s of BS8102:2009 were met.As aired on Grand Designs on 6th January 2021.

The 2,500m2 basement extends beyond the property where a blue-green roof will be created over a suspended podium deck to form part of the garden. The Triton team worked closely with waterproofing and blue-green roof design specialists, EPG, to create a waterproofing strategy and utilised a comprehensive Construction Quality Assurance protocol agreed between Triton and EPG. The Triton team had been called in by main contractor, Era Build Ltd, to replace a previous supplier who had been unable to provide a warranty. After detailing was complete; Triton Approved Contractor, Cast Contracting Ltd (CCL), installed the systems.

Our purposeOn behalf of Amye Defence Services, Acclaim Contracts Ltd was commissioned to address the aging roof of the building, which was leaking despite receiving patch repairs over the past 20 years. The Ministry of Defence’s Project Allenby/Connaught demonstrates the Government’s commitment to maintaining defence estates.The £1.45bn scheme is a 35-year commitment to providing modern, high quality, fully serviced, purpose built living and working accommodation for 18,700 soldiers. It involves the new build and refurbishment of more than 550 buildings across Salisbury Plain and Aldershot, including upgrading Allenby’s Building 51, otherwise known as the Sports Pavilion.Our solutionAcclaim turned to Langley to provide all the material necessary to complete the work. After stripping the original roof to the existing plywood deck, the team fitted new treated timber around the perimeter and new uPVC fascia. The current edge trims, perimeter check kerbs, and extended flues were removed to ensure regulatory 150mm clearance was achieved once the new roof covering was installed. Langley’s HT180 attachment layer was loose-laid and nailed into place to provide appropriate protection to the timber deck while the “hot works” above were undertaken. Langley’s TA-20 Flat Roofing System was installed across the roof area, with insulation to achieve the regulatory requirement of 0.18W/m2K. SA-20 Flat Roofing Detailing System was used in fire risk areas, in line with Safe2Torch guidance. The range of Langley’s TA systems complies with Broof(t4) classification and has a Local Authority Building Control (LABC) assured accreditation. Under MOAT 31, Langley’s Parafor 30 GS (cap sheet to the TA system) achieves a ‘resistance to damage” rating of R4. It is independently certified by the BBA to deliver a life expectancy of at least 40 years, one of the longest available in the UK.Acclaim fitted Langley’s ParaFurb Refurbishment Outlets to upgrade the internal outlets where possible, cleaning and priming those where the design precluded the use of ParaFurb. We installed New Code 5 lead pipe sleeves to flues and hot pipes to a minimum 150mm above the waterproofing. In addition, Langley’s ParaTrim GRP Edge Trim was fitted to all the kerbs.“It carried great weight with us that Acclaim worked in partnership with Langley, who offers an independent insurance-backed guarantee. That is indicative of pride and confidence in its work, giving synergy with Amey. It also gives us, and our client the Ministry of Defence, that the refurbished estate at Allenby will serve and be fit for purpose for decades to come.”Will Loates, Service Delivery Area Manager, Amey

Delta’s Structural Waterproofing Consultant, Paul Green, CSSW alongside Delta’s MD, Kevin Dodds, were appointed to the design team to collaborate with the Architects, Engineers, Main and Sub-Contractors to fulfil the role of Waterproofing Design Specialists in providing a reliable, watertight solution for this substantial project.The large-scale basement project consists of a 4-storey deepbasement located close to the River Thames in Central London.The proposed subterranean space would offer multiple usage. This complex project required a waterproofing design which is, able to cope with intermittent/regular hydrostatic pressures created not just by groundwater, but also geographical tidal impacts from the river Thames and potential stress challenges caused by the surrounding infrastructure such as heavily trafficked railway lines in the development’s vicinity.Structures that experience a high level of vibration fromsurrounding infrastructure can, over time, have a high propensity to suffer cracks, which could lead to failure of some waterproofing solutions, so therefore careful considerations should be incorporated into the overall waterproofing design from those aspects and, the impacts these factors can have on an elected waterproofing system.Delta’s design philosophy rotated around creating a robust and suitable waterproofing design, the structure design, a continuous system, sequencing and installation, future maintenance, and serviceability, whilst able to fulfil requirements set out in BS 8102:2022 Protection of below ground structures against water ingress. Code of practice. The British Standard which governs waterproofing of substructures.
