Natural stone paving using pedestals - Douglas, Isle of Man
Wallbarn Ltd
This was a large roof terrace on a private domestic project. The area was flooded and had needed to be re-laid with waterproofing and a significant fall constructed into the deck to allow the often considerable amounts of rainwater to escape the roof deck.
The contractor asked Wallbarn for a suitable but cost effective solution so we recommended Wallbarn 9mm rubber supports along with levelling shims.
The area was re-waterproofed in the inverted waterproofing method, the membrane being covered with rigid insulation boards and a loose laid geotextile fabric to act as a separation layer .

Separating floor soundproofing for assisted living flat, Merseyside
Hush Acoustics
Harbour Light Assisted Living CIC housing association approached Hush Acoustics to upgrade the floor within one of its flats to offer a higher level of soundproofing in line with the specific requirements of one of its tenants.The housing association, which specialises in providing bespoke accommodation and services to assist people with disabilities to fulfil their responsibilities as tenants and help them live an independent life, sought to improve the acoustic performance of a separating floor in the flat for a new resident. The individual suffered from an Autistic Spectrum Condition (ASC), also referred to as Autism Spectrum Disorder (ASD), which meant any flooring solution had to be appropriate for their needs, not only to reduce both impact and airborne ‘noise nuisance’ encroaching to the flat below, but also to ensure the final floor finish could be fully bonded to the acoustic substrate. The potential noise issues were regarded as higher than typical domestic noise which meant a more robust specification was required.The solution was provided by Hush Mat 15 with Hush Ply 28 overlaid. This provided the required mass, flexibility and isolation, as well as a robust surface to allow the floor covering to be directly bonded, ensuring it could not be lifted.
Reinforced Gravel Car Parking Installation at Belper School using X-Grid Gravel Grid
GCL Products Ltd
With the introduction of new sports areas and a sixth form college, The Belper School faced a significant shortage of parking spaces. The growing demand for additional parking became evident as staff, visitors, and students resorted to parking on grassed areas. Consequently, numerous muddy patches emerged around the school grounds, negatively impacting the area's aesthetics and making it increasingly inaccessible. Moreover, this led to an increase in the amount of mud brought inside the school, placing a greater burden on the caretaking and cleaning staff.To address the drainage issues and offer an environmentally friendly alternative to concrete or tarmac, the school opted for X-Grid® as a permeable alternative for traditional car park surfacing. The school identified several areas around the premises as suitable locations for the car parks and proceeded to excavate them. A compacted hardcore base made of MoT-type stone was used to establish a strong and stable sub-base for the X-Grid®. By placing a geotextile membrane over the hardcore, the school minimised the risk of weed growth and created a separation layer between the build-up layers. The X-Grid® was then installed on a well-screeded sand blinding layer and filled with durable decorative gravel.By replacing the existing grassed areas with X-Grid® filled with gravel, Belper School successfully resolved their overcrowded car parks without the need for additional drainage infrastructure. The highly permeable nature of X-Grid® facilitated the controlled dispersion of surface water back into the water table. Consequently, the amount of mud around the school grounds was significantly reduced, virtually eliminating it altogether. This enabled the availability of parking spaces throughout the year, providing staff, visitors, and students with ample parking options while preserving the aesthetic appeal of their surroundings. Moreover, the use of X-Grid® ensured that the gravel remained in place, eliminating migration and greatly reducing surface maintenance requirements, thus keeping the areas looking as attractive as possible.

Remedial Basement Waterproofing
Delta Membrane Systems Ltd
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 Gunnery, Kent
Delta Membrane Systems Ltd
The Gunnery, Kent is a unique and interesting project.
Delta Membranes were appointed as Waterproofing Designer to transform an unused fort/home in Kingsdown, Kent. The building was situated 92ft on a cliff edge.
The Gunnery was originally a military base with extended underground rooms and thought to have ‘secret rooms’ underground. The building had suffered from fire damage as well as vandalism over the years and had been left to ruin.
During a site visit various considerations were given to what Delta product would be best suited to the job, given the restrictions imposed by the existing structure.

GT Yarmouth - Beattie passive - Retrofit
Intelligent Membranes
An old block of apartments in Gt. Yarmouth getting a low carbon Retrofit for a higher, cleaner living standard and reduced energy bills.
Passive Purple has been used externally on this huge scale block of apartments. with no margin for error and tricky details throughout, a liquid applied airtight membrane was the only way going forward. The building was being insulated externally and getting a whole new façade from render to aluminium panels. With the residents still inhabiting the building this had to be done quickly and easily with maximum results. Being a liquid applied airtight membrane, any cracks, gaps, and service penetration leaks in the existing building fabric quickly became thing of the past. That and the hundreds of Panel brackets being installed to support the new façade going on, this Retrofit had multiple penetrations and tricky details. Making good of the building fabric and awkward brackets with a near on impenetrable adhesion, Passive Purple made fast work of this great conversion, impossible for any other method.
Being in liquid state on application, Passive Purple can be applied onto most/any surface (See data sheets for more information) and will find its way into all the unseeable tiny gaps and cracks all buildings will undoubtably have. Like this old pebble dashed façade, any rough, uneven and awkward areas are no longer an issue, our products simply flow into these areas. We also have the fibre reinforced Passive Purple brush, used on this job to prepare the brackets by filling the larger gaps between that of the bracket and the existing wall and also the large penetrating bolts.
A huge win and demonstration of the power of liquid products by Intelligent Membranes.

Damp Remedial Solutions
Delta Membrane Systems Ltd
Chepstow is a beautiful town and community in Monmouthshire, Wales. Located on the tidal River Wye, roughly 2 miles before the confluence of the River Severn. Steeped in history, Chepstow’s Great Tower keep was commissioned by William the Conqueror following the Battle of Hastings.With high ceilings and spaces which feel luxurious there is simply something that draws us towards the vast expanse of space and the warmth offered by listing buildings such as converted barns and farmhouses, often because of their idyllic rural locations.Delta Registered Installers, Tywi Damp Proofing were commissioned with the sympathetic conversion of an old farmhouse located in Chepstow. The project scope was to convert 1 listed farmhouse into 5 separate dwellings.Original features, such as 5ft thick walls were embraced in this conversion project.During initial inspections, penetrating damp was found. Penetrating damp is often referred to as lateral damp, which is the development of moisture through walls, roofs or any ground area of a structure. If left untreated this penetrating damp will cause problems for the structure envelope and can lead to significant damage to the fabric. Penetrating damp can be caused by a combination of problems such as the structure’s age, construction and exposed location.
