Coating Waterproofing

Liquid-applied waterproofing for walls, decks, gutters and complex shapes that sheet membranes cannot reach — seamless, flexible and fully bonded.

What it is

A seamless liquid membrane that fits any shape

Coating waterproofing is applied as a liquid that cures into a continuous, flexible film with no joints or overlaps. That makes it ideal for detailed areas — parapets, gutters, upstands, planter boxes and irregular surfaces — where sheet membranes can’t sit flat.

We select the right chemistry (polyurethane, acrylic or cementitious-hybrid) for each surface and exposure, then apply in multiple coats for a reliable, monitored film thickness.

Questions

Coating Waterproofing FAQ

How is coating different from torch-on membrane?

Torch-on is a heat-bonded sheet best for large flat roofs. Coating is a liquid film that is better for walls, detailed areas and complex shapes. We recommend the right one after inspecting your building.

Can I walk on a coated surface?

Yes, with the right system. We specify a foot-traffic-grade coating with a protective top layer where the area will be used.

Does coating handle cracks?

Flexible coatings bridge minor cracks and movement. Larger structural cracks are repaired first, then coated over.

How many coats do you apply?

Typically two to three coats to reach the specified film thickness — thickness is what makes a coating reliable, not just colour coverage.

Is the inspection free?

Yes — a free site inspection with a full photo report, no obligation.
