Zanth Building Waterproofing was founded on a simple belief: water damage is an engineering problem, not a cosmetic one. We diagnose the true source of leakage and dampness, then apply proven systems that last for years — whether it’s a decades-old terrace or a brand-new structure.
A proud second-generation family business, Zanth carries forward years of inherited craftsmanship — now combined with modern materials science and engineering discipline.
From building repair and terrace waterproofing to cementitious systems, gypsum plastering and premium painting, our crews bring discipline and craftsmanship to every square foot.
Prathap and Prasanth are twin brothers who own and lead Zanth Waterproofing — pairing science depth with proven on-site civil engineering execution.
