Damp Proof Membrane DPM 1200 gauge (100m²) is a black membrane material used within solid concrete floors to prevent the rise of moisture or damp through structure flooring and for most construction damp proofing requirements.

The DPM can be used as either below the slab application, directly below the flooring surface or in a sandwich construction, between base concrete and the screed.

Damp Proof Membrane 300 micron (25m x 4m) is a high puncture resistant material manufactured from recycled polythene to meet PIFA and BBA standards.

Not recommended for use as a general gas proof barrier system on Brownfield sites or in applications where gases such as radon are present.


Damp Proof Membrane (DPM) Installation:

 · Unless the application surface is smooth it should be blinded with compacted soft sand to guarantee a soft bed, free from any objects that may puncture the membrane during installation or when concrete is applied.

 · It is recommended that the DPM should be covered with a protective layer or screed as soon as possible after the membrane has been installed.

 · Care should be taken when applying concrete or screed on top of the DPM to avoid stretching or the DPM being displaced.

 · When joining two sheets a minimum overlap of 150mm should be provided between each of the sheets.

 · For the best waterproof protection when making a join a double welted fold should be formed between the joining sheets.

 · This should be formed by an overlap of 300mm from both sheets.

 · Alternatively the 150mm overlap can be sealed with 100mm wide jointing tape.

 · Any Punctures in the membrane should be patched with sheets of identical thickness lapped at least 150mm away from the perforation edge and sealed with double sided pressure sensitive tape.

 · When installed within structures Damp Proof Membrane should be linked to the Damp Proof Course within the structure walls to form a continuous damp proof barrier throughout the structure.

We can help to calculate price per m2 or linear meter (one meter in length) cost, please just contact us via phone 02081910776, email or live chat. Alternatively, you can work it out yourself quickly and easily: to get cost per meter square please divide price shown in orange area by ''Required area (m2)'' Example price of £28.80 divided by board coverage 2.88m2 = cost of £10.00 per m2.


No matter whether you choose a local installer or a national company, there’s a few tips to help you find the right installer for your home insulation improvements, such as asking for recommendations and making sure that they’re part of a certification scheme. This makes sure that they have the right skills and standards of workmanship to carry out the installation, and you can be sure that they know exactly what they are doing.


1. Thermal inspection picture in portfolio

It’s worth seeing a installer’s previous work. There’s no harm asking if you can see any properties nearby that they’ve installed insulation in. Best way would be to see Infrared Thermal Imaging Inspections. Thermal cameras spot small, but key changes in temperature in different areas of a house, identifying problematic areas that the human eye never could and some that a visual inspection could only hypothesize.

2. Reviews

Along with checking recommendations and previous work, finding reviews online can often be a great way to find out if they provide a good service or not. However, it’s best not to solely rely on reviews you may find or review websites, as there’s no controlling who writes them.

3. Compare prices

Comparing prices will also ensure companies can’t take advantage of you and give you a fair price. 

4. Word of Mouth

The best way to find a great insulation installer is through recommendations. Make sure you ask friends and family. They will most likely give you their honest opinion and can tell you from first hand experience.


Whether you require a wall, cladding, external wall, loft or floor insulation fitted, you can find and hire your local insulation installers from popular UK web pages. A simple internet search will return thousands of potential installers near your area.
