Heritage Structural Rehabilitation — Colombo
COLOMBO MUNICIPAL COUNCIL BUILDING
Client: Colombo Municipal Council (CMC)

A sensitive and technically demanding project — structural rehabilitation and waterproofing of the iconic colonial-era Colombo Municipal Council building. The project required crystalline waterproofing applied directly to the original concrete structure with minimal surface build-up to preserve the historic facade. The self-healing property of crystalline systems is particularly valuable for heritage structures where minor cracking continues to occur due to age and structural movement.

Client: Road Development Authority (RDA), Sri Lanka

A high-profile national infrastructure project — WaterProofing.lk waterproofed the entire deck of the Kohuwala Flyover, one of Colombo's critical elevated road structures.
