Internal tanking is considered to be a negative side waterproofing system.
Although TCS will always choose the best combined system of all our product range to ensure a
completely successfully designed water proofing system in most instances we will recommend a cavity
drained membrane system complete with associated drainage either gravity or pump driven.
Battery Back up System is also available where power cuts may be a problem.
TCS always work to BSS8102(1990) when designing internal waterproofing systems as this BS document states
that for those seeking the maximum assurance against failure a
CAVITY DRAINAGE MEMBRANE SYSTEM is the best choice.
All TCS cavity drain membranes are designed to allow water to percolate behind the
drainage layer to a point where it will be either pumped out or removed by gravity.
A Cavity drainage system does not allow hydrostatic pressure to build up and if water does ingress we
design a comprehensive pattern of drainage channels and sumps with twin or more pump
systems installed to pump water ingress to an external discharge point.
We always install a remote alarm system to ensure that in the event of pump failure the client is aware.
We have various stud depths which create the drainage void to choose from.
4mm up to 20mm depths of cavity are achievable on both horizontal and vertical surfaces.
We can install 2 types of Plaster direct membrane Plaster Base and Plaster Mesh.
Plasterboard or other types of board can be dot and dabbed to this material.
All the membrane products we use are also methane and radon barriers.
