DL stands for Direct Lay. The first Permadeck, ever, was laid directly onto asphalt in 1986. Twenty one years later, to renew its guarantee, the surface was re-coated with Permadeck thus extending the roof’s life another 20 to 30 years. Permadeck cannot be laid on uneven, rough, friable or bitumen surfaces that would dissolve on contact with the liquid resin. Please contact us regarding the suitability of your surface.
Suitable surfaces are brushed and cleaned and a ‘seal’ layer of a fully reinforced Permadeck base coat is overlaid. This layer takes the place of the more familiar DryPly used on most conventional roofs. The Permadeck is then laid up in the usual way with reinforced base and coloured top layers.
Known movement joints should have ‘movement joint’ trims overlaid or other precautions taken.
PermadeckDL is completely seamless and highly resistant to the effects of the weather & lying water. It can mould around existing details and even up behind parapets, rooflights and down into outlets. It can take any amount of ‘service’ foot traffic.
