About This Service

Complete Waterproofing Solutions
for Every Structure

We specialize in providing high-quality waterproofing solutions in Sri Lanka, ensuring your buildings are protected from water damage. With years of expertise, our team guarantees reliable and durable services tailored to your specific needs.

Water infiltration is one of the most damaging and costly problems a building can face. Once water penetrates the structure, it leads to corrosion of reinforcement bars, concrete spalling, mold growth, and ultimately, structural failure. Our certified waterproofing systems stop water at the source — before it can cause damage.

Using exclusively Supercrete New Zealand certified products, we provide long-lasting protection proven to perform in Sri Lanka's tropical climate — high humidity, heavy monsoon rainfall, and intense UV exposure.

Common Questions

Waterproofing FAQs

How long does waterproofing last?
Our waterproofing systems are warranted for 10 years in writing. When applied by certified specialists using Supercrete NZ products, the actual lifespan is often significantly longer — especially for crystalline systems that become a permanent part of the concrete.
Do you offer a free inspection before quoting?
Yes — our certified specialist will visit your property, assess the type and extent of water intrusion, and recommend the most appropriate system. This site inspection is completely free with no obligation.
Can waterproofing be done without removing tiles?
In many cases, yes. Our crystalline injection and negative-side systems can be applied without removing existing finishes. However, for positive-side applications on new construction or major remediation, surface preparation may be required. We'll advise the least disruptive approach after the site inspection.
Do you serve areas outside Colombo?
Yes — we provide island-wide service across all 25 districts of Sri Lanka, from Jaffna to Matara and everywhere in between. Travel costs for site inspections outside the Western Province may apply for very remote locations.
