Our Solutions
What it is:
A non-destructive inspection method that captures temperature variations on surfaces.
It helps identify hidden moisture, leakage paths, and root causes before treatment.
This enables precise treatment planning and avoids unnecessary dismantling.
What it is:
Chemical grout is injected under pressure into cracks and voids.
It seals leakage paths internally without dismantling existing finishes.
The method is effective for both active and concealed leakages.
Used at:
Washrooms, terrace tile joints, basements, ceilings
What it is:
Polyurethane grout is injected into water-bearing cracks and joints.
It expands on contact with water and blocks active leakage effectively.
The system performs even under continuous water pressure.
Used at:
Basements, underground structures, lift pits, construction joints

What it is:
A reinforced waterproofing system with fabric embedded between coating layers.
It enhances strength, flexibility, and crack resistance. This makes it suitable
for large and movement-prone surfaces.
Used at:
Terraces, balconies, podiums, large open slabs.
What it is:
A traditional waterproofing system that creates proper slope using brick bat coba.
It offers long-term durability for flat roof surfaces and ensures effective drainage
and water management.
Used at:
Old terraces, flat roofs with slope issues, heavy water exposure areas.
What it is:
Flexible sealing systems are applied to expansion joints. They allow structural
movement while preventing water ingress, protecting adjacent waterproofing systems.
Used at:
Expansion joints, basements, podiums, large structural slabs.
