This consists of a major 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 within the flooring surface or corners, restore them with a sand/cement grout or concrete. When dry, take away all traces of dust and canopy the surface with a water-based rubberised bitumen emulsion paint . Then, continue portray the bitumen about 100mm up the wall, utilizing the manufacturer’s instructions as a information to the number of coats. Finally, lay about 50mm of sand/cement screed on top of the ultimate coat, guaranteeing the bitumen is visible on the partitions.
