Type A waterproofing and basement tanking products work by blocking water from entering the building, whilst Type C cavity drainage systems redirect the water to an appropriate drainage point.

Basement Waterproofing Membranes: Since the introduction of the British Standard for waterproofing structures below ground (BS 8102:1990, subsequently replaced by BS 8102: 2009), the use of cavity drain membranes has become the most popular form of structural waterproofing in the UK.

Our systems can easily deal with aggressive ground-water conditions, where basements are liable to flooding, or indeed where simple dampness, contamination or salting problems are prevalent.Platinum Chemicalsoffer an extensive range of membrane types from shallow studded 'slimline' profiles (Newton 601 Slimline Membrane) to 8mm studded membranes (Newton 508 Cavity Drain Membrane;Platon P8 Cavity Drain Membrane) to deep 20mm Cavity Drain membranes (Newton 520 Cavity Drain Membrane) which allows a wide variety of situations to be dealt with providing tailored solutions. The final choice of membrane is determined by two factors: 1). The finish required and 2). The anticipated flow rate.
