This consists of a main waterproofing system (e.g. Drybase Elasticised Tanking Slurryor Drybase Tanking Slurry) protected by a secondary drainage layer .
If there are any cracks, eroded mortar joints or gaps in the flooring floor or corners, restore them with a sand/cement grout or concrete. When dry, remove all traces of dust and cover the floor with a water-based rubberised bitumen emulsion paint .
