A Damp Proof Membrane ( ) is essential for flooring. Find out when it should be used. 👇
It acts as a barrier against moisture rising from the ground or concrete slab, preventing issues like dampness, warping, and loosening of floor coverings by protecting the flooring material from moisture damage, particularly when installed on concrete subfloors that can be prone to humidity.
Here are some Key benefits of why DPMs (such as ARDEX UK DPM 1C) should form part of your subfloor prep in areas that have rising moisture.
✅ Moisture protection:
The primary function of a DPM is to stop moisture vapour from penetrating through the concrete and reaching the flooring above, which can cause significant damage.
✅ Prevents mold growth:
By preventing moisture build-up, a DPM helps to inhibit the growth of mold and bacteria known as pink fungus (Serratia Marcescens) on the floor surface.
✅ Structural integrity:
Dampness can weaken the subfloor structure, leading to cracks and uneven surfaces, which a DPM helps to prevent.
✅ Application on concrete floors:
DPMs are particularly important when installing flooring on concrete subfloors, especially in areas with high humidity or where the ground is damp.
✅ Building Regulations:
In many regions, building regulations require the use of a DPM under flooring to ensure proper moisture protection.
