Nano Waterproofing
Nano Waterproofing is our specialist division for roofs, wet areas, pools and basements. We find where the water gets in, then seal it with the right system, backed by 1,223 completed waterproofing jobs.
Roof & Building Waterproofing
Waterproofing protects a structure from leaks, damp, mould and deterioration of building materials. Getting it right depends on a correct diagnosis and the right system for the surface, not just another coat of paint.
Our crews apply torch-on membranes, liquid-applied systems, PU coatings and PU injection grouting on homes, condominiums, hotels, offices and factories across the Klang Valley, using systems from brands such as Sika, Polybit, Bostik and Mapei.

Systems & methods
