What’s A Damp Proof Membrane?

A damp proof membrane, also known as a DPM, is a barrier that prevents moisture from penetrating through it. It serves to prevent rising damp by stopping the absorption of moisture through capillary action in materials such as concrete slabs.

This type of membrane is commonly used in conjunction with damp proof course treatments. If you suspect any moisture-related issues in your home, it’s essential to conduct an inspection promptly. At Sussex Damp Treatments, we offer comprehensive services ranging from initial surveys and inspections to full treatment and repairs for all types of damp problems.

Benefits Of A DPM And A DPC To Avoid Rising Damp

Although it is technically possible to use a damp proof membrane (DPM) without completing a full damp proof course (DPC), it is highly recommended that you instal a DPC in order to effectively prevent moisture from rising through the walls and floors.

A DPC acts as a waterproof barrier, running throughout the length and breadth of your wall, preventing groundwater from creeping up through capillary action. Meanwhile, a DPM prevents moisture by attaching a waterproof silicone membrane to the structure. To regulate moisture levels, polyethene film can be placed beneath concrete sheets using this standard method of protecting structures against water damage caused by rain or other sources of moisture.

Shotcrete cement provides additional resistance against pressure and humidity. Cavity walls between interior and exterior spaces keep water out while masonry walls can be sealed with pressure grouting or chemical DPCs for permanent waterproofing solutions that prevent wetness on walls and floors within rooms.

Damp Proof Membrane Vs Other Solutions

Damp Treatment – Liquid Or Sheet Membrane?

In the realm of damp proofing, there are two options available: liquid solutions and sheet membranes. The former involves a chemical cream that is less invasive but requires significant drying time and multiple coats to achieve the desired thickness and consistency. On the other hand, sheet membranes offer simplicity in installation as they can be directly placed on sub-surfaces before flooring installation. They come in various sizes and are particularly useful for covering extensive areas with their specially designed double-sided tape overlap securing mechanism. While both methods have their advantages, it’s important to consider factors such as convenience, speed of application, and effectiveness when deciding which solution to use for your specific needs.

Other Solutions For Damp Proofing

In the past, materials such as bitumen, slates, lead, pitch, asphalt or low absorption bricks were commonly used to create damp-proof courses in buildings dating back to circa 1900. However, nowadays the most cost-effective method of preventing moisture from rising through walls and floors is by using a DPM. Sussex Damp Treatments offers expert consultation and advice on implementing this approach. Our team of professionals can provide you with a quote for our services upon request. Don’t hesitate to contact us today at 01273 257 212 for more information on how we can help protect your property from dampness and its associated problems.

When Is A Damp Proofing Membrane Necessary?

Capillary action is the culprit behind rising damp, as it draws moisture up through a building’s porous fabric. This can occur due to faults in or the absence of a damp-proof course (DPC) or damp-proof membrane (DPM), which also leads to penetrating moisture. To prevent such occurrences, an effective physical barrier like a DPM must be applied along with a DPC. A DPM is essentially a polyethene sheet that prevents capillary action from causing moisture to enter concrete slabs placed on top of it.

For waterproofing requirements, specialist recommendations suggest using dense concrete built on a hardcore bed and supplied with DPM above or below it for ground-supported floors. The same continuous barrier could be used for walls, piers and other structures too.

What Costs Are Involved In Applying A Damp Proof Membrane?

The cost of a professional DPM installation varies depending on the location and provider. However, an average charge of £70 per metre for wall treatment is a reasonable estimate, which amounts to approximately £275-£300 per wall for damp injection alone. It’s worth noting that additional cosmetic work such as re-plastering and post-treatment décor will increase the overall cost but will also enhance your structure’s appearance, providing peace of mind that your home will remain free from dampness for many years to come. Investing in these services can transform your living space into a more pleasant environment while ensuring its longevity.
