Waterproofing additives

The use of render additives after the insertion of a damp proof course or tanking slurry is an extremely important part of the dampproofing/waterproofing process.

Firstly if water has come from the ground it is likely to be contaminated by salt (our additives reduce sulphate movement) and secondly the use of render additives require us to use less water, less water means less capillaries in our render making it less susceptible to water migration. This cement waterproofing additive allows for your flooring to remain damp free for an extended period and eliminates the risk of mould.
