APPLICATIONS:

OGMT DPM 250μm is suitable for use below concrete floor slabs in most domestic or low-rise buildings site conditions, not subject to hydrostatic pressure.  If hydrostatic pressure exists please contact technical support for advice. For jointing adjacent sheets, double sided (10m x 50mm) and single sided (33m x 50mm) jointing tape should be used.

IMPORTANT:

When a Vapour Con  trol Layer is required please consult OGMT Technical. We do not recommend OGMT DPM 250μm for this purpose.

INSTALLATION:

OGMT Damp Proof Membranes form an effective barrier to the passage of moisture from the ground. The DPM must be continuous and the membrane should be installed on a compacted sand blinding layer or smooth concrete float finish.  Care should be taken to ensure that the membrane is not stretched or displaced when placing sand, concrete or screed over the membrane.
