This project, internal waterproofing for basement, the main challenge is always coordinating with other trades as well as the main contractors.
On this project Beautiful Basements worked with the main developer to install the waterproofing system just prior to the flooring and windows being put in to minimise the amount of exposure of the system.
The other major challenge was the drainage system was designed and installed prior to consultation with Beautiful Basements. To overcome this, the usual drainage designs were adjusted and a custom solution for this project was developed and installed.
Type C – Drained cavity protection
At the base of all external walls a recessed concrete channel was created within the slab. All walls and the floor were lined with two types of cavity drainage membrane (CDM) . One to allow for dry lining and insulation to be installed, another for space saving in the internal entrance staircase.
These membranes were linked to sump chambers via the recessed perimeter channels. Within the sump is two pumps and a high-level alarm. This system is designed to catch any water and discharge it automatically. Flushing and maintenance points were installed to allow future servicing of the system.
Both waterproofing systems were designed by Beautiful Basements’ Structural Surveyors in Structural Waterproofing (CSSW) in accordance with BS8102:2009
All waterproofing materials were supplied by Triton Systems Ltd
