The single most important factor with any basement conversion project is ensuring that the tanking process (waterproofing) is handled in a correct professional manner by competent trained persons. The waterproofing of a structure below ground level is a specialist application it should only ever be undertaken by trained qualified operatives, the tanking of the Basement is the single most important element of the build as it is the very foundation on which all other elements of the build rely on.

Waterproofing guidance and advice is laid out in BS8102:2009, the industry recognized Code of Practice for the protection of below ground structures against the ingress of water from the surrounding ground. This code categorises the different forms of waterproofing available into three types: Type A (Barrier) protection: This form of waterproofing is dependent on a separate barrier system applied to the structure, often referred to as tanking, it involves the application of an appropriate waterproofing barrier to the walls, base floor and where required, the ceiling of a below ground structure. Effectively providing an internal barrier deflecting water ingress into the building. The procedures and systems utilised by Grand Designs Construction when tanking a Basement Conversion have been thoroughly vetted over time to provide outstanding results first time every time. Type B (structurally integral) protection: This is provided by the structure itself. Type C (drained) protection: This method is achieved by diverting the ingress of water into the building into a central draining point, it requires the use of an adequate internal water management system. Utilizing a dimpled, flexible, high density polymer sheet membrane which is applied against the internal face of a structure it is designed to intercept water penetrating the structure, and directing any water ingress to a suitable drainage facility, a factor of which this system is wholly reliant. The Cheshire Damp Cavity Drainage Membrane System will provide Type C protection in accordance with BS8102.
