How To Choose The Right DPM Thickness

Buying Damp Proof Membrane

It is critical to select the correct damp proof sheet for your job. It will have an impact not just on the building itself, but also on the prices forecasted for every project. In this post, we explain the many different thicknesses of DPM available, as well as which membrane is ideal for you.

What is damp proof membrane?

Damp proofing, also known as damp proof course or DPC, is a common form of damp prevention. DPM is generally used in floors, whereas DPC is designed to assist combat inside walls.

Damp-proof membrane is typically made of polyethylene plastic. Plastic is highly long-lasting and moisture resistant, protecting other components such as masonry.

When is damp proof membrane used?

Damp-proof membranes may (and should) be used in a number of sectors of building. They're especially useful in structures that might have problems with damp.

A damp-proof membrane will generally be erected during the construction of a new building's concrete floor to prevent rising damp from damaging it.

Requirements in the UK

The use of damp-proof membranes in construction is governed by British Standards -  they state that the DPM should be at least 1200 gauge (300 micrometres).

A thinner sheet might violate building codes and be a costly repair, so 1200 is always suggested. With a thickness of more than 1200 gauge, DPM sheets are available. The maximum width is generally determined by the width of your work piece.

Make sure to enquire about any restrictions that your architect or a structural engineer may tell you about your design. Check with the local government to see if there are any limitations.

Choosing the right thickness of membrane

Buying in bulk can save you money, but it's also important to remember that not all goods are the same. There are numerous different types of building membranes available, including DPM and DPC.

Damp Proof Membrane

Damp proofing membrane, as previously said, is classed as either DPM and DPC. They are often utilised in walls or floors to prevent dampness.

Gas Membranes

Carbon monoxide and radon, among other things, are kept out of living areas by carbon dioxide gas membranes.

Whether you need a gas membrane is determined by the building's circumstances (for example, if it's a factory) or the presence of pollutants in the neighbourhood.

Vapour Membranes

Vapour barriers and damp-proof membranes are similar in many ways. While damp proof membranes are intended to keep water from going through, vapour barriers include the function of preventing water accumulation owing to condensation.

Vapour barriers are frequently used in timber construction and may be utilised in the floor, wall, and roof systems.

Tanking Membranes

The tanking membrane is comparable to a damp proof membrane in that it is porous. Tanking is meant to provide unrivalled, heavy-duty water protection in particularly vulnerable areas such as basements. The tanking membrane is typically thicker and more costly than DPM or DPC.
