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 – and Newton was involved.
The structure included 59 concrete balconies, all requiring waterproofing with a product was a minimum fire rating of A2-s1-d0, tested to BS EN 13501-1.
Not only was Newton able to recommend a product already used on a similar project beforehand, but it was 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.
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 the installation in two phases of efficient and detailed waterproofing.
Thanks to a meticulous eye for details, 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 ratings, and the installation was completed quickly without compromising the programme of the build.

The use of flame retardant panels in construction is far from a new idea, but the innovation in manufacture and performance in panels has been significant, if little understood.
