| Waterproofing A Shopping Centre, Maidstone|
The Chequers Shopping Centre in Maidstone required a waterproofing system to be installed to create a dry, habitable area. Newton System 500 was installed by Newton Specialist Basement Contractor, Gulliver Timber Treatments and the area is now being used as a gym.
Waterproofing A Shopping Centre
Waterproofing this shopping centre in Maidstone as the basement had serious water ingress issues rendering the space unusable for a period of years. With commercial retail space at a premium in Maidstone, the management of the shopping centre acquired the services of Newton Specialist Basement Contractor Gulliver Timber Treatments to design and install a robust waterproofing system to bring the area back into commercial use.
The 1000 sq metre floor area showed signs of water seeping through construction joints in the slab and the vertical RC walls were also defective and letting large amounts of water through. In the first instance, dewatering pipes were installed on the vertical planes and an engineered sprayed concrete was applied to all the vertical surfaces to slow the ingression of water through the elevations. The leaking movement joints were raked out and Gullivers’ applied FlexProof-X1 to these areas to stop the flow of water.
A perimeter Basedrain was installed into the wall/floor junction as a means of intercepting and removing water that entered through the structure to a safe natural drainage option. The walls were curtain hung with Newton 508 cavity drain membrane and the floors treated with Newton 520 – 20mm floor membrane. A floor screed was applied directly on top of the 520 membrane and an independent dry lining frame was installed throughout as a finish to the internal space.
Gulliver’s application of the Newton System 500 gave a fully maintainable and robust waterproofing system in accordance with BS8102:2009. The space is now a grade 3 habitable space and has been let out to a fitness company.
“This was an interesting project, not only because of the size of the installation but also the complexities involved in the system design.However the adaptability, strength and integrity of the Newton systems meant the client was extremely impressed with the finished product.” Roger Gulliver – Gulliver Timber Treatments
