Frequently asked questions

We offer DPMs in various thicknesses, typically ranging from 250 microns to 1200 microns. The most suitable thickness depends on your specific project requirements and local building regulations.

The appropriate grade depends on factors such as soil type, load requirements, and drainage needs. Our knowledgeable team can help you in selecting the best grade based on your project specifications. Get in touch today for advice.

Most breather membranes are suitable for both roof and wall applications. However, we always recommend checking the product specifications to ensure compatibility with your project.

A vapour barrier typically has a higher resistance to water vapour transmission than a vapour control layer (VCL). The choice between the 2 types depends on your building's design and the desired level of vapour control.


Damp Proof Course (DPC)

damp proof course (DPC) prevents rising dampness by halting capillary action to ensure walls remain dry and free from common issues like efflorescence and internal damage.

Damp Proof Membrane (DPM)

damp proof membrane (DPM) offers essential protection against ground moisture by creating a reliable barrier against water ingress, preventing issues like concrete degradation and flooring failure.

Gas Membrane

Gas membranes block harmful ground gases, ensuring compliance with building regulations and creating safe environments.

Geotextile Membrane

Geotextile membranes excel in soil separation, filtration and reinforcement applications, improving ground stability and drainage.

Breather Membrane

Breather membranes help create high-performance building envelopes managing moisture effectively and reducing condensation risks while improving thermal efficiency.

Polythene Membrane

Polythene membranes offer a cost-effective and reliable solution for moisture control.

Vapour Barrier

This low-permeability vapour barrier membrane prevents warm, moist air from penetrating wall and roof structures, reducing the risk of interstitial condensation and mould growth.

Tanking Membrane

tanking membrane offers excellent protection against hydrostatic pressure, ensuring basements and underground structures remain water-tight.
