Our Products


1: App Waterproofing Membranes

Concrete is highly porous and as such allow water and other chemicals to infiltrate it. If left unattended, this can also lead to the deterioration of a building . To prevent this , we supply and install high quality bituminous membranes on flat roofs, concrete gutters, basements, retaining walls and other concrete structures. The membranes are 4mm, mineral finish and we extend 10 years workmanship guarantee.

This is a crystalline waterproofing product composed of cement, graded aggregates and proprietary reactive agents and additives. It is used as a surface applied, permanently active waterproofing treatment for concrete.
