Visqueen High Performance DPM – BBA Approved – is Visqueen’s premium grade Damp Proof Membrane manufactured from prime virgin polymers for use as a Type “A” damp proof membrane as defined by BS EN 13967: 2012. In this post, we demonstrate how to form a damp proof joint using Visqueen High Performance Damp Proof Membrane. Watch the video here:

The tools of the trade required for this are a roller with a neoprene wheel and a sharp knife or pair of scissors. To complete the job, you will need Visqueen High Performance Damp Proof Membrane (HPDPM), Visqueen double sided jointing tape, and Visqueen single sided jointing tape.

High Performance DPM

Approximately 50mm from the edge of the membrane, apply the double sided jointing tape to the HPDPM.

Using the roller, press it down over the tape to ensure that it is fully bonded to the membrane. Next, peel off the release film on the tape and position the next piece of HPDPM on the exposed tape ensuring that the membrane covers the whole width of the tape.

Again, use the roller to ensure a tight seal is created by applying pressure to the newly formed joint.

Now use the single sided jointing tape and position it equidistant over the lap joint.

Applications and use

Visqueen High Performance DPM is suitable for use in concrete floors in domestic and commercial (schools, hospitals leisure, shopping centres etc.) applications, in accordance with clause 11 of CP 102:1973, where there may be capillary rise of moisture but not where it may be subject to hydrostatic pressure.

If such a circumstance arises, Visqueen Tanking Membranes should be used. Where there is a risk that the ground may be waterlogged, sub-soil drainage in accordance with CP 102 and BS 8102 should be provided.

Visqueen High Performance DPM is also suitable for applications such as heavy duty raft foundations, steel reinforced slabs etc where a durable, robust and high puncture resistant membrane is required. For jointing adjacent sheets of Visqueen DPM, DPM to DPC and DPC to DPC, Visqueen Jointing System should be used.
