Frequently Asked Questions

What waterproofing systems do you use?

Adseal is a certified applicator for Sika, Viking, Nuralite, Ardex, Cohe and Equus waterproofing systems. We select the optimal system for each project based on the specific requirements — whether it's TPO membranes for roofing, liquid-applied membranes for decks and balconies, cementitious tanking for basements, or polyurethane coatings for industrial floors.

Yes, absolutely. As certified applicators for all our manufacturer partners, every installation comes with the full manufacturer's warranty. This provides you with comprehensive protection and complete peace of mind. We also stand behind our workmanship with our own quality guarantee.

We handle projects of all sizes across commercial, residential and industrial sectors — from small residential deck waterproofing to large-scale commercial roofing, basement tanking for multi-storey developments, concrete repair for infrastructure projects, and protective coatings for industrial facilities. No project is too big or too small.

Project timelines vary depending on the scope, scale and complexity of the works. A small residential deck waterproofing can be completed in 2-3 days, while a large commercial roofing or basement tanking project may take several weeks. We provide detailed timelines during the quotation phase and keep you informed throughout the project.
