If your basement is experiencing dampness or water ingress, our proven Type ‘A’ barrier systems could be the ideal solution. Commonly known as “tanking,” these internal waterproofing systems are designed to prevent groundwater from penetrating the structure, eliminating unwanted seepage and damp patches.
We offer a range of advanced technologies, including active migratory crystalline treatments and cementitious waterproof renders. A key advantage of Type ‘A’ systems is their versatility—they can be applied to both new and existing structures, making them especially valuable when external waterproofing isn’t feasible.
