The main contractors employed a specialist basement contractor to design a specification that would suit both the new-build and existing aspects of the comprehensive basement waterproofing project. After several detailed surveys had been carried out, the specialist basement contractor formulated a specification, which included a complete external system for all new-build elevations and a comprehensive cavity drainage system to the internal walls and floors, both new and existing.

An external type-A system, it comprised render and Bituthene 4000 drainage membranes utilised with fillet details and waterstops. 

For the essential internal drainage system, Wykamol 8mm was recommended for all walls while Wykamol 20mm waterproofing membrane was selected for use on the floors and the perimeter drainage at the junctions between floors and walls. The perimeter drain was then efficiently and quickly connected to the new drainage system which is guaranteed to prevent water ingress and provide low-maintenance performance for many years.

Basement tanking is an essential part of any construction or renovation project and using only the best materials and contractors will give complete security, satisfaction and peace of mind. Wykamol cellar waterproofing products are used in many diverse basement conversions, constructions and excavations. They believe that any project should only be attempted using superior materials and a reputable contractor.
