Damp Proof Membranes: The Ultimate Solution for Damp Walls

Damp walls can be a nightmare for homeowners and property managers alike, causing mould, musty odours, and even structural damage if left unchecked. Fortunately, advances in building materials have given rise to new solutions to address this issue, including Damp Proof Membranes.

These innovative membranes are manufactured using high-density polyethylene (HDPE) with a mesh surface on one side, providing a superior physical barrier compared to other methods.

In this blog, we will explore the details of how Damp Proof Membranes work, their benefits, and how they can be the ultimate solution for damp walls.


The Science Behind Damp Proof Membranes

Damp Proof Membranes work by providing a robust physical barrier that isolates the walls from damp substrates.

The HDPE material used to create the membrane is hydrophilic, meaning it can retain water and help to prevent water ingress. It is designed to withstand the most demanding of conditions, including high humidity, moisture and the movement of the building.

In addition to the physical barrier, the mesh surface on one side of the membrane creates a superb mechanical key for plaster, render or dot and dab plasterboard.

This feature ensures that the membrane can be plastered or rendered to provide a smooth finish with excellent adhesion. As a result, the walls are resistant to dampness and remain aesthetically pleasing.


Vapour Equalisation: The Role of the Studded Design

Another unique feature of a Damp Proof Membranes is the studded design facing the wall, creating air channels that facilitate vapour equalisation between the membrane and the wall.

Vapour equalisation enables moisture within the structure to evaporate without creating condensation problems, preventing the accumulation of condensation-related damage in the walls.

This feature ensures the longevity of the membrane by reducing the potential for failure due to the accumulation of moisture.


Superior Advantages of Damp Proof Membranes

Damp Proof Membranes offer superior advantages when compared to conventional solutions for damp walls.

Foremost amongst the advantages is the excellent physical barrier that impedes dampness from entering the walls. Unlike conventional damp proofing materials, Damp Proof Membranes provide a sturdy and durable hydrophilic layer that effectively isolates the internals from damp substrates.

Another significant advantage of Damp Proof Membranes is that they are versatile enough to work with different types of walls and building structures.

They can be applied to brick, stone and concrete walls, and they can also be used in different areas of a property, including basements, cellars, and garages. If using in a basement, it's recommended to use a membrane with at least an 8mm depth stud. This versatility makes them an ideal solution for properties of all types.

Furthermore, Damp Proof Membranes are relatively easy to install, reducing labour costs and disruption to daily operations. They do not require any specialist skills to install, and once installed, they offer quick and effective results in damp proofing walls.
