Challenge

The project is the roof deck of a residential home.

The waterproofing contractor, Graybuilt prepared the concrete substrate by removing all dust, oils and other contaminants.

The area was primed with Duromix WBE Hibuild, two-part Water-Based Epoxy Primer.

Graybuilt then installed Flexible Neutral Cure Silicone Joint Sealant to all wall/floor junctions and all other joints in the substrate, to accommodate anticipated movement.

Two coats of Duroproof BLW were applied to the area. A total membrane thickness of 1.2mm was achieved throughout.

Membrane Protection was later installed prior to filling the deck with soil and plants.

Solution

Waterproofing a garden roof deck is obviously to prevent water/moisture from entering the substrate and causing leaks. On this particular project, there is the requirement for added membrane protection, being a Drainage Cell that site on the horizontal portion of the membrane and Drainage Sheet for the vertical sections. This protection is essential to protect the membrane against any loose or aggressive fill that could potentially damage and pierce the membrane
