1200 Gauge DPM Handy Pack 4m x 5m

Black DPM for Concrete Floors

A 1200 gauge DPM available as a single 4m x 5m sheet for smaller job convenience. The single DPM sheet helps protect buildings from moisture in the ground. As a DPM for concrete floors, it is designed for use with solid ground floors that are not subject to hydrostatic pressure.

The 1200 Gauge DPM provides a barrier that prevents ground water transmitting to the final floor finish whether that’s timber, laminate, carpet or tiles. High quality DPMs like this provide long term protection to the upper surface of the floor. You should always consider a DPM before installing any flooring at ground level.

Under normal conditions, the polythene DPM will act as an effective barrier to moisture for the lifetime of the concrete slab.

The 1200 gauge membrane has a DPM thickness of 300μm, making it highly puncture resistant. On smooth or blinded surfaces, the 1200 gauge membrane will not be damaged by normal foot or site traffic such as wheelbarrows. However, care must be taken to avoid damage during installation, particularly when handling building materials and equipment over the surface and when laying concrete or screeds.

For larger damp proofing jobs, you should opt for our DPM Rolls, 4m x 25m.

Uses

Our black DPM handy pack can be installed in the following ways:

• As an oversite membrane, between a blinded hardcore bed and the base concrete slab
• As a sandwich membrane in a base concrete slab
• Between the base concrete slab and the screed

Installing a 1200 Gauge DPM

1200 gauge DPMs are laid either under a new concrete slab or on top of it to prevent moisture transmission. To install a DPM under a slab in construction, the hardcore bed must have a blinded surface.

Where there are adjacent DPM sheets, they must be overlapped by at least 150mm, sealed with double-sided DPM tape and further sealed over the face of the joint with 75mm wide jointing tape.

In the rare event of punctures or perforations in a DPM, you need to patch them with a DPM sheet of identical thickness. Overlap the membranes at least 150mm beyond the limits of the puncture and seal with double-sided DPM tape.

Note: The floor DPMs must be continuous with the damp proof course (DPC) in the surrounding walls.
