Protect floors, concrete slabs and building structures against ground moisture and rising damp with this Heavy Duty Plus Damp Proof Membrane (DPM).
Manufactured from tough 300 micron / 1200 gauge polythene, this heavy duty waterproof membrane provides a strong moisture barrier for use beneath concrete floors, screeds, slabs and other building applications.
Supplied as a convenient 4m x 5m Handy Pack, it provides approximately 20m² of coverage before allowing for overlaps, making it ideal for smaller building projects, extensions, garages, sheds and repair work where a full-size roll of DPM is not required.
At 1200 gauge / 300 micron / 0.30mm thick, this membrane is considerably more substantial than lightweight polythene sheeting.
Its heavy duty construction provides excellent strength and durability while remaining flexible enough to position around floor areas, corners and construction details.
For customers searching for heavy duty damp proof membrane, 1200 gauge DPM, 300 micron DPM or polythene damp proof membrane, this Handy Pack provides a practical solution without the need to purchase a larger roll.
A damp proof membrane, commonly known as a DPM, is a waterproof barrier installed within a building construction to help prevent moisture passing from the ground into the floor and building above.
When correctly installed, the membrane creates a continuous moisture-resistant layer beneath the floor construction.
This can help protect:
against problems associated with excessive ground moisture.
Moisture entering a building from the ground can lead to a range of problems if adequate damp protection is not installed.
This 300 micron heavy duty DPM helps create a waterproof barrier that prevents ground moisture from passing upwards through the floor construction.
Correct use of a DPM can help reduce the risk of:
This Heavy Duty Plus DPM Handy Pack is suitable for a wide range of domestic and construction applications, including:
One of the biggest benefits of this product is the convenient 4m x 5m pack size.
A standard full roll of damp proof membrane can provide far more material than is required for smaller projects. This Handy Pack gives you approximately 20 square metres of DPM, making it particularly useful for smaller floor areas.
It is an ideal option for:
This can reduce unnecessary waste and means you don’t need to purchase a large 100m² roll for a relatively small project.
Damp proof membrane thickness is commonly expressed in either gauge or microns.
For this product:
1200 Gauge = 300 Micron = approximately 0.30mm
The higher the gauge and micron measurement, the thicker the polythene membrane.
At 300 microns, this product provides a substantial heavy duty sheet suitable for demanding building applications where greater strength is required.
The membrane is manufactured from durable polythene, one of the most commonly used materials for damp proof membranes.
Its flexible construction makes it easier to position over prepared surfaces and form around corners, edges and construction details.
At the same time, the heavy duty 300 micron thickness provides increased resistance to accidental damage compared with thinner lightweight polythene sheeting.
