System Components




Storage and Handling


Visqueen Zedex High Bond Damp Proof Course should be stored vertically, under cover in its original packaging.

Care should be taken when handling the product in line with current manual handling regulations.



Preparation


Visqueen Zedex High Bond Damp Proof Course can be cut with a sharp retractable safety knife.

Where the DPC is being fully bonded to the substrate, the surface should be primed with Visqueen HP Tanking Primer and allowed to dry thoroughly.

Material must be warmed above 5°C prior to unrolling.



Installation


DPCs and DPC cavity trays systems to be designed and installed in accordance with the relevant sections of BS 8215:1991, PD 6697:2019 and BS 8000-3:2020.

When built into a masonry wall construction Visqueen Zedex High Bond Damp Proof Course should be installed on an even bed of wet mortar, and any perforations in adjacent courses of masonry should be completely filled with mortar. To ensure mortar adhesion, as soon as possible after laying the DPC, lay at least one further course of masonry including a bed of mortar. Where the specification requires, the DPC can be fully heat bonded to the primed substrate. The DPC must extend through the full thickness of the masonry wall, including pointing, applied rendering or other facing materials.

When used as a site formed cavity tray, the DPC can be either built-in to the inner leaf or surface fixed to the cavity face of the inner leaf.

When surface fixing the cavity tray, the substrate should be primed with Visqueen HP Tanking Primer and allowed to dry. The DPC should be bonded to the inner leaf using Visqueen Zedex Jointing Tape and permanently secured using Visqueen Fixing Strip and fixing suitable for the substrate. Visqueen Fixing Pins for masonry substrates are available.

Complex or awkward junctions e.g. corners, changes of level etc can be effectively sealed on site with the DPC when the lap joints are heat bonded.

All laps should be a minimum of 100mm and either bonded with Visqueen Zedex Jointing Tape or heat bonded with appropriate equipment e.g. propane gas torch.
