A damp proof membrane (DPM), or otherwise known as damp proofing membrane, serves the purpose of preventing moisture from permeating it. It also has an additional benefit, that of protecting against penetrating damp. For example, a polyethene sheeting placed beneath a concrete slab hinders the concrete from absorbing moisture via capillary action, often referred to as rising damp. This is frequently used in conjunction with damp proof course (DPC) treatments.
A survey is the initial step in resolving any moisture issues in your home. London Damp Treatments offer services for all damp-related requirements in both East and West London, from inspection to full treatment, repairs and improvements to your property.

It is possible to use a damp-proof membrane (DPM) without taking a damp-proof course, however it is recommended to install a damp-proof course (DPC) to effectively prevent moisture from rising through the walls and/or floors. A DPC is a waterproof barrier that runs the length and breadth of a wall, and capillary action prevents groundwater from seeping up. A DPM, on the other hand, attaches a waterproof silicone membrane to the structure and places a polyethene film underneath a sheet of concrete to regulate moisture. This is a common method of protecting structures from moisture and water, such as rain, and includes pressure-resistant cement, like shotcrete. Cavity walls are also used to keep water out, and pressure grouting seals masonry walls. The chemical DPC is used to stop wet walls and floors by preventing water from entering and permanently waterproofing the walls and floors of a room.
When considering damp proofing, you have the choice of a liquid solution (cream) or a sheet membrane. Liquid chemical damp proofing is less invasive, however, it is more time-consuming as multiple coats may be needed and a considerable period of drying is required. It could also be difficult to achieve the right depth of coverage and a consistent finish over the entire area.
Sheet membranes are a breeze to install, coming in various sizes and able to be laid directly on the sub-surface before the flooring is installed. DPM sheets are quite fast and easy when covering large regions, and the overlap can be fastened with double-sided tape designed for the purpose.
Bitumen, slate, lead, pitch, asphalt, and low-absorption bricks were formerly employed to construct damp-proof courses. During the Victorian era, these materials gained much popularity and can be seen in buildings from around 1900.
Nowadays, the most cost-efficient way of preventing moisture from ascending walls and floors is to utilise a DPM.

Capillary action draws moisture up through a building’s porous material, resulting in rising damp. Deficiencies in, or the lack of, a damp-proof course (DPC) or damp-proof membrane (DPM) can cause rising damp and some penetrating dampness.
A DPM (Damp Proof Membrane) is necessary when installing a DPC (Damp Proof Course) to create an effective physical obstacle to stop rising damp due to capillary action.
A Damp Proof Membrane (DPM) is an effective way to stop moisture from penetrating the concrete slab. Specialist recommendations suggest that for a ground-supported floor to meet waterproofing requirements, the ground should be covered with dense concrete and a DPM should be placed on top of the hardcore bed. The DPM can be located either above or below the concrete, and should be continuous with the Damp Proof Course (DPC) found in walls, piers, and other structures. If you need advice on the best rising damp solutions, please contact our damp treatments team to book a damp and timber survey.
The cost of a professional DPM installation may differ depending on location and provider. On average, £70 per metre of wall treatment is a fair price – approximately £275-£300 per wall.
The damp injection alone costs this amount. Enhancing your structure with re-plastering and post-treatment décor will raise the total, yet bring a far more pleasing environment and the assurance of being damp-free for the years ahead.
