How We Work

The formula for lasting waterproofing: four stages

When the right survey, the right system and the right application come together, waterproofing lasts. We run every project with the same discipline, in four stages.

  1. Survey

    We inspect the building on site and identify the water source, pressure direction and substrate condition with measurements and tests.

  2. Design

    We define the system, layer details and schedule for the conditions of use and prepare an itemised written quotation.

  3. Application

    Our experienced crews install everything from surface preparation to the final coat to manufacturer specifications, fully documented.

  4. Inspection

    We check every seam and detail, flood-test suitable surfaces and hand over with an application report.

Membrane, liquid, cementitious or geomembrane — we choose what suits the substrate and water pressure.

One team, one contact

The same team from survey to inspection — responsibility never changes hands.

Inspection and reporting

Every stage is photo-documented, tested and handed over with a report.
