Cellar Tanking for Residential Cellar
In association with Newton we were called in to look at a large new-build residence in Chelmsford where the basement had already been constructed out of ‘waterproof’ concrete with admixtures. However, with the structure leaking in multiple locations, because of experience Newton recommended us to redesign the waterproofing approach for this high-end residential build.
The Solution
After visiting site to provide a quote, we recognised that the Newton CDM internal cavity drainage membrane system, classified as ‘Type C’ waterproofing by BS 8102:2009, would be the safest and most effective solution.
As the most failsafe form of basement waterproofing, the system was designed to capture and manage the water that was still coming through the structure, resolving the problem once and for all.
The Newton CDM System was installed in response to a concrete structure with admixtures that was leaking
The failsafe system consists of wall/floor membranes, fixings, tapes, drainage, insulation and sump chamber
The experienced installers at A.P. Gooch were able to install the system quickly and efficiently throughout
We began by installing Newton 508 to the walls as the first form of defence. This was followed by a floor build-up consisting of Newton Basedrain to channel captured water, Newton Fibran XPS 500-C thermal insulation board and spacer, and more Newton 508 membrane.
Finally, the system delivers captured water to a Newton Titan Pro sump chamber, designed specifically for use with the Newton CDM System, and equipped with dual Newton CP400 pumps to ensure that there will always be a safe means of removing captured water from the building.
The Result
Not only were the homeowners left with a dry and safe basement space in which to create their dream games room, bar and cinema, but the British Standard-compliant waterproofing system will effectively protect the room for years to come.
The level of professionalism and support demonstrated by us working alongside the builder has fostered a productive working relationship for years to come.
