Waterproofing remediation

Duraseal can repair everything from leaking basements, podium decks, tennis courts, balconies, car park roofs, plant rooms, planter boxes, building facades, fire tanks, wine cellars and even chimneys.

Contaminated site remediation

With today’s technology we are able to build on contaminated sites which would not of been possible previously without major earthworks. Gasses can be caught rising from the ground and vented above the roof line so they do not enter a habitable space.
