Basement Development London

Little Boltons

Basement waterproofing sump and channels.

A basement development by London based design and build basement specialist company Basement Force - utilising John Newton & Co's Basement Waterproofing Products.

Originally a five story house in West London, the developers

discovered a bricked up space below the ground floor and it was decided to excavate and create a basement level to increase the floor area by an extra 100 sqm.

Rubble and earth were removed from five rooms below the ground floor and it was underpinned to secure the foundations. Newton System 500 was used as the waterproofing solution. All five rooms have had Newton Basedrain installed at the wall/floor junction to intercept any water ingressing at this weak point in a structure and draining round the perimeter of the structure to a Newton Titan pump system with two pumps installed. Insulation was applied to the floor and Newton 508 placed above it as a waterproof barrier bringing the whole to be level with the top of the Newton Basedrain to accept a minimum 50mm screed. Jetting eyes have also been installed to create a maintainable system that complies with BS8102.

An independent frame will be applied to the walls to accept insulated dry-lining, plaster skim and decoration. The use of insulated dry-lining is now common practice to comply with recent changes to building regulations regarding improvements to the thermal properties of habitable dwellings. However, this increases the risk of interstitial condensation forming should the temperature of the internal face of the membrane fall below the dew point. The use of our specially designed Newton Basedrain prevents any potential interstitial condensation from causing a problem.

This project in The Little Boltons in South West London was created by the London basement development company Basement Force who have an extensive knowledge of the London basement market. There will be fresh photographs as the project progresses.
