"flooring joint fillers and sealants"

Roof and facade cover... CHALLENGE For the design of a youth centre a Belgian architect wanted to have a fully homogeneous and waterproof cover for the roof and the facade. This envelope technique needed to be combined with a more ecological and aesthetically pleasing green wall design. SOLUTION For the waterproofing of the roof surface a standard RENOLIT ALKORPLAN roofing membrane was used. For the facades the architects opted for a RENOLIT ALKORSOLAR fixing system as the base to attach the final greenwall system. As the roof and the wall covering (waterproofing) are the same material there were no jointing issues. The whole building has been covered with RENOLIT ALKORPLAN roofing membrane. The facade details were similarly accomplished as standard roof details and RENOLIT ALKORSOLAR profiles were used to fix the rain water pipes from the roof.

New Clubhouse Fits in Perfectly with Historic City Pool to Create a New CenterSpread across 3 acres in the Mission District of San Francisco is Garfield Square Park. A popular recreation hub for the community, the park includes a historically significant indoor swimming pool with its much loved culturally significant murals, clubhouse, basketball courts, and courtyard with BBQ facilities and splash pad. The pool and clubhouse had served the community for decades and were in need of updates to not only meet current code but also changing needs. The joint venture of PTA/TEF Design of San Francisco won the commission in 2016 and was tasked by the City of San Francisco with renovating the historic indoor pool and unifying it with a newly designed clubhouse and lobby.

More than 20,000m² of Sto’s external wall insulation system has been specified for two residential schemes at Cherrywood, Ireland’s largest urban development driven forward by real estate group Hines and its joint venture partners, APG Asset Management over the past seven years.Located on a 360-hectare site to the south of Dublin, Cherrywood is expected to serve a population of 25,000 people, offering more than 7,700 new homes, six schools, three parks and leisure facilities.Henry J Lyons Architects selected the StoTherm Mineral insulation system for apartment blocks forming part of the first and second phase of the residential construction. Now complete, the first scheme comprises 431 homes divided into two equally-sized blocks. The second consists of 520 units spread across three blocks and is due to be completed in Summer 2023. Sto installation work was carried out by applicators Platt Reilly.Consisting of mineral fibre insulation boards, the StoTherm Mineral system provides a high level of thermal performance and fire protection. It has been installed onto lightweight steel frames using Sto-Rotofix Plus. Thanks to a unique spiral design, these fixings help to create a seamless façade across all the blocks as well as a cavity behind the insulation board allowing any excess moisture to drain. Using the Sto-Rotofix-Plus, any unevenness in the substrate can be easily rectified by adjusting the insulation boards after they have been installed. This means there is no need for unsightly expansion joints and a smooth surface can be created ready for applying the render.All the apartment blocks will be finished with the StoSilco silicone resin render to provide high levels of water repellence and resistance to algae and fungus growth. 

Bucking the trend for dairy brick, Brooklyn Brewery opted for close to 8,000 sq. ft. of urethane cement for major upgrade works to its manufacturing facility located at the former matzo plant where it has operated since 1996.

Two new apartment buildings in Kent have been given a thermally-efficient and visually-striking façade thanks to the use of an external wall insulation system from Sto. The two new blocks in Ashford - Stour Heights and Somerset Heights – have a single-skin construction, comprising a reinforced concrete frame with concrete block infill, and they benefit from the installation of StoTherm Mineral external wall insulation, with a StoCleyer B mineral brick slip and StoSilco render façade finish.“An alternative insulation system was originally proposed for these buildings,” says John Mahoney of Sheffield-based J Mahoney Architects. “As things progressed a different solution was required to meet the demands of the various parties involved in the project. Sto pretty much leads the pack in terms of quality, and the StoTherm Mineral system was able to satisfy everyone’s requirements, so it became the obvious choice. The fact that Sto could work with us and provide technical support was also extremely helpful.”The BBA-certified StoTherm Mineral external wall insulation system uses mineral-fibre boards to provide outstanding thermal performance, combined with reliable fire protection and effective sound insulation. Its efficient single-leaf construction and external installation do not compromise the building’s interior space, and it can be installed without the need for additional expansion joints.For the new buildings, it was installed using Sto’s unique Sto-Rotofix plus mechanical fixing system. The helical Rotofix fixings create a cavity behind the insulation board, which can be easily adjusted after installation to ensure a level outer surface is created. This system combines the ease-of-use of ETICS anchors with the flexibility of a mechanical rail system, but without the material and labour cost of installing the rails.“The StoCleyer B brick slips were specified to meet certain planning requirements,” adds John Mahoney. “An alternative brick solution was originally considered, but Sto was able to manufacture slips which were a perfect match for the proposed original. The fact that they were also fully compatible with the Sto insulation system was another significant point in their favour.”The new buildings have added 109 one- and two-bedroomed flats which are spread across the five floors of Stour Heights, and the three floors of Somerset Heights.

Installed by Kawneer’s approved specialist subcontractor FK Group, the £25.3 million project, designed by FCB Studios, was the first to use Kawneer’s newly enhanced AA®110 Curtain Wall system that features a bespoke expansion joint, which allows a building movement tolerance of +/- 15 mm. Creating a sense of scale and vibrancy, the white profiled terracotta ceramic façades contrast the earthy tones of the perimeter buildings in a modern interpretation of the grand Victorian warehouses nearby. The high-performance Curtain Wall was accompanied by AA®720 Side Hung Open-In Windows to deliver a high level of thermal performance throughout. Using passive principles, the high insulation building fabric coupled with solar control glazing, address the energy requirements for heating and cooling.

Award-winning global practice, WilkinsonEyre, specified bricks and brick slips from innovation-led manufacturer, Vandersanden, to emphasise the horizontal volumes and architectural context of the contemporary, new Graduate Centre at Queen Mary University in London. Zero®, a new brick system from Vandersanden, offers a contemporary joint-free appearance and was WilkinsonEyre’s material of choice for the external walls of this 80m-long, seven-storey ground-scraper. Instead of being pointed up to the face of the bricks, the mortar is set well back, with rainwater draining behind. The use of brick draws attention to the horizontality of the building’s volumes and blends with neighbouring buildings...To find out more about the bricks used in this project or to see the wide range of high-quality bricks available from Vandersanden, click on the 'View more' link

Glazing Vision’s three-wall box rooflight has provided a rooftop with more de rigueur, and one which takes advantage of the spectacular views overlooking the Perth shorelines.Keen to unlock and utilise the space on top of this newly built residential home, and further add value to this property, an innovative “glass box” was introduced to provide easy access to the roof terrace.Luxurious, modern and upbeat, this new build property has been carefully created with family life in mind. The floor plan involves family separation and considered zoning of the property.The ground floor provides a secluded escape from the excitement of the first floor, with a detailed layout which enables the clients to relax. A big theatre room and access to the garden offers a chilled out environment, hidden away from neighbours.The first floor is created for living in, with a completely open planned lounge, diner and kitchen. Set higher up, it allows for views across the beach and over the garden courtyard. Thus, it was important to ensure that high quality glazing was specified throughout to make the most of the wonderful views.Tasked with sourcing and installing the windows and doors on this modern new build property, Next Generation Glass director Steve Payne mentions how the client had come to them enquiring about skylights. After a lot of research into the different profiles available in Australia and after various different drawings and ideas, the outcome wasn’t looking good.It was a visit to the UK which led Steve to Glazing Vision, thankful of a recommendation from a contact of his. “Since my first contact, we decided it was a great product and became a distributor of Glazing Vision products in Australia”.After discussing the details of the job, a three wall box rooflight was recommended, helping to provide access to the clients roof terrace and providing wonderful views of the majestic presence of the Indian Ocean in the background.“It really is a great product and all that see it are in awe of it” explains Steve Payne, director of Next Generation Glass.The Glazing Vision three-wall box rooflight is fixed to your existing building structure, thereby facilitating the full use of the roof top terrace but operates in the same way as our freestanding box rooflight. The sleek aluminium framework and perfectly edged glass-to-glass joints create a stunning contemporary finished design which reflects the style of this property.This home’s rooftop terrace is the culmination of meticulous tweaking of the planning codes, and the reward is breath-taking views of Perth, with a beautiful backdrop of the ocean behind. It was in fact these planning codes which guided them towards the three-wall box rooflight, as the extra head height was required when coming up the stairs. Also allowing the homeowner to climb the stairwell whilst the rooflight is retracting into its open position, without having to ‘bow their head’.Fitted with minimal and contemporary outdoor furniture to increase the sense of openness. The new roof top allows the homeowner an additional ‘room with a view’, perfect for entertaining or for relaxing and enjoying the stunning views on offer.Having completed their first project with Glazing Vision, Steve Payne mentions how easy the whole process was, and that most of the hard work was undertaken by Glazing Vision. It was a simple installation process for a company like Next Generation Glass who are used to cranes in their scope of works.

Sotech worked with installers Stanmore on the Barrett Homes Residential Development Westgate House, which was a £500 million mixed-use regeneration project, designed by London-based Assael Architecture and located in Brentford, Middlesex. Westgate House is an NHBC (National House Building Council) project, and Sotech initially became involved in the project because the original specified cladding did not fit NHBC requirements. To provide an alternative, we worked with installers Stanmore to specify our Optima IPC Interlocking Pressed Plank Rainscreen cladding system for the project, which is both NHBC approved and full independently CWCT tested.Over 2000sqm of secretly fixed Interlocking Pressed Plank panels were used on the Westgate House development. 4 different colour panels were specified; 3 with a matt powder-coated finish and one using a bespoke, pre-coat, high gloss special finish.The combination of a series of PPC matt panels arranged in bands, combined with a reflective high gloss panel stripe created a sophisticated, modern appearance for the building’s exterior.There were some design challenges involved in this project, but all were tackled successfully through the development of bespoke areas of the system. Initially, Sotech had to develop a new, bespoke joint method between the Optima IPC rainscreen cladding panels to avoid slab deflection because a lot of the panels spanned floor slab areas. These customised joints allow the panels to move between the slabs like a damper while maintaining a pristine exterior.For the curved area of the building, Sotech developed a bespoke substructure for the Optima IPC panels with a different panel depth than that used for the flat rainscreen cladding. This involved setting the grid behind the IPC panels differently to the rest of the project, ensuring a seamless line from the flat areas to the curved areas. Although it was a complex design challenge, the solution was effective and ensured a uniform, flawless appearance.Our secretly fixed Optima IPC system was specified in particular because the long narrow panels were ideal for bringing the architect’s vision to life, and because it could be easily adapted where necessary.As well as the IPC rainscreen cladding, Sotech provided all the fascias and soffits required for the development.Westgate House involved the regeneration of iconic Grade II listed Art Deco building Wallis House and the construction of over 800 residential apartments spread across 17 new buildings.The site used advanced construction techniques to minimise waste and also ensured that homes benefit from solar panels and other renewable energy techniques.In addition to new housing, the Westgate House development also offers communal gardens, a health and fitness centre, a convenience store, a medical surgery and hotel, as well as cafes, bars and restaurants.The training facility and showroom at Sotech is open to specifiers and contractors, where all of our Optima Rainscreen Systems are on display alongside the widest selection of materials and finishes, including pre and post coat aluminium, ACM, Copper, Zinc, Stainless Steel and Anodised.

As part of the Wandsworth regeneration programme to increase the number of affordable homes, Wates Residential were awarded the contract to build a new, six-storey block of apartments on the Shuttleworth Road.The structure included 59 concrete balconies, all requiring waterproofing with a product with a minimum fire rating of A2-s1-d0, tested to BS EN 13501-1.Not only were Newton able to recommend a product that had already been used on a similar project this year, they were also able to recommend the expert services of Newton Specialist Contractor Arti Structural Waterproofing.The minimum fire rating of A2-s1-d0 now precludes the polyurethane and polyurea products that were commonly used on balconies, so Newton recommended the cementitious and modified-polymer Newton 103-S membrane. As well as carrying the required fire rating, 103-S can resist extremely high positive and negative water pressure, forming a hard, durable coating with a degree of elasticity that makes it ideal for protecting concrete.Arti also used Newton 203-RM to create smoothing fillets, and Newton 912-RT to reinforce the 103-S over the joints, details and changes in direction.On site, Arti also needed to work flexibly, as the programme could not proceed without the waterproofing and fireproofing of the balcony upstands. However, due to the propping of the concrete formwork to the floors above, Arti had to execute their installation in two phases of efficient and detailed waterproofing.Thanks to a meticulous eye for detail, as well as careful planning and thorough preparation of the concrete balconies, Arti were able to complete the waterproofing of all 59 balconies in two stages. This was managed as well as delivering the required A2-s1-d0 fire rating, and the installation was completed quickly without compromising the programme of the build.

The ETB building is dedicated to research, development and demonstration (RD&D) in sustainable energy technologies. It incorporates energy efficient materials and is designed to minimise its demands for heating, cooling, lighting and ventilation. It actually produces more energy than it requires, heating the neighbouring Institute of Mental Health Building.Approximately 1000m2 of Ash & Lacy Façade was specified on the building’s two main elevations in the VariAL CF1 configuration. VariAL CF1 is a concealed-fix, baffle-jointed cassette rainscreen with a fully adjustable support system, primarily used for horizontal application on walls and for soffits. Designed to fit in with the high-tech building design and to appear to exude their own energy, the panels were manufactured in Alucobond Spectra Sacura ACM finish. This provides a quite stunning two-tone iridescent effect that shows ever changing hues of pink and silver that constantly vary as the angle of view or illumination changes.

RAF Akrotiri is home to the Cyprus Operations Support Unit providing joint support to British Forces Cyprus and operations in the region to protect the UK’s strategic interests.The base was opened in 1955 to initially relieve the pressure on the main RAF station on the island, and has since grown into a forward thinking training unit. However, back in October 2015 the RAF base was subject to many reports when 114 refugees landed at the British Sovereign base; a critical front line station for the MOD and Royal Air Force.The BriefIn order to detect, deter and delay any potential threat, the client had a number of requirements to meet the increasing level of security for the base.Increase protection of assets and personnel with their security fence line.Approved for Government Use fencing system.Provide a robust solution to stand up against the rigours of daily life and exposure to harsh aviation fuels.

The M4 Junction 3-12 motorway upgrade project, which started construction in July 2018, is designed to increase capacity, and reduce congestion between Junction 3 (Hayes) and Junction 12 (Theale). In the sections where there is no pre-existing hard shoulder for conversion into an additional running lane, a total of 11 overbridges needed to be demolished and replaced with longer decks to enable continuity of the widened carriageway. The £848m project is due for completion in Spring 2022, by which time it is expected that approximately 680,000t of material will have been excavated, 1.8M.m² of new surface laid, 130km of cabling installed and 63km of concrete barrier positioned. Cordek were approached by the Principal Contractor Balfour Beatty VINCI joint venture to provide a lightweight structural fill solution to be used for the embankment construction adjoining the Datchet Road Overbridge, between Junction 5 and Junction 6.

The ChallengeBrick Kiln Lane is a development of seven, four and five-bedroomed, cottage-style units situated at the end of residential road in a quiet, rural area of Leicestershire. There are two different designs: four L-shaped and three rectangular. Each of the seven houses needed unique elements of detailing – including window variations, render and brickwork – to distinguish it from its neighbour.The SolutionHampton Rural Blend brick was chosen to complement the character style of the development. Combined with recessed mortar joints, the brick blend, which is made up of several shades, creates a more aged appearance that helps the houses to sit comfortably within their environment.The BenefitsThe brick detailing on the units includes dentilation around the eaves and gables, and segmental arches over windows, all of which are in keeping with the traditional architectural style of the units and serve to enhance their aesthetic appeal.

Challenge: The structure was had severe structural degradation due to the ingress of moisture and water over its near 100-year life. Corrosion to the steelframe resulted in tensile forces cracking and moving the brick skin, also causing a cracked façade. Strategy: ICCP was used as a method to control corrosion whilst the cracking and movement were repaired. This involved LoCem® and +point® AACM anode mortar to be grouted in the bed joints, alongside embedded corrosion rate sensors for service life tracking (AchillesICP and AiMS). LoCem® is a low carbon cement alternative, that can also act as a cathodic protection anode. Outcome: The structure was restored to be used as high-value residential apartments, saving tonnes of embodied carbon and eliminated the option of demolition. The embedded system successfully controlled and monitored corrosion for the long term, adding an additional 100 years to the structure’s service life.
