How to install the damp proof course roll

• If the application surface is not smooth, blind it with compacted soft sand for a soft bed. This ensures it does not have objects that can puncture the membrane when it’s being installed
• The damp proof course roll should be covered with a screed or protective layer as soon as it has been installed
• Be careful when applying screed or concrete on top of the damp proof course roll so it doesn’t get displaced or stretched
• If you’re joining two sheets, ensure there’s a minimum overlap of 150mm between each sheet
• If there are any punctures in the membrane, patch with sheets of identical thickness. Seal with double-sided pressure-sensitive tape and ensure they lap at least 150mm away from the perforation edge
