Newton Waterproofing has designed and installed a waterproofing and fireproofing solution for 59 balconies on a new six-storey block of apartments in South West London.
As part of the Wandsworth Regeneration Programme aimed at increasing the number of affordable homes in the area, Wates Residential, one of the UK’s leading housing developers operating in London and the South, were awarded the contract to build the new apartments on the Shuttleworth Road.
To do this, they enlisted the help of Newton Waterproofing’s specialist contractor, Arti Structural Waterproofing.
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.
Newton Waterproofing’s MD Warren Muschialli explained:
“Not only were Newton able to recommend a product that had previously been used on a similar project, but we were also able to recommend the expert services of our 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 completed 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.
Arti Structural Waterproofing Managing Director Lucian Ardeleanu commented:
“We were very pleased to have had the opportunity to use Newton’s unique products to provide a robust and quick solution for Wates Residential to meet the new building fire regulations at the same time as achieving the required waterproofing to the balcony structures.”
“It has also been a pleasure to work with a very professional construction management team throughout, and we were very pleased with the final outcome of this project.”
