Damp Proof Membranes

Specialists Across Southern England & Wales

Servicing homes throughout Dorset and Hampshire, Bath, Bristol and South Wales —  we specialise in installing and repairing damp proof membranes (DPMs) as part of our comprehensive damp-proofing services. Our fully-trained surveyors diagnose moisture risk and apply membrane systems designed to protect walls, floors and sub-floors from persistent water ingress and damp damage.

What Is a Damp Proof Membrane & Why It Matters

A damp proof membrane (DPM) is a durable sheet or coating material installed to prevent moisture from passing into your building fabric through floors, walls or slabs.

These membranes are typically made of polyethene or specialist materials and are used in situations where traditional damp-proof courses may not suffice — for example, in conversions, basements, floors above ground, or when moisture paths are lateral rather than rising.

Correct membrane installation offers a reliable barrier and helps avoid problems like damp patches, salt contamination, mould growth and structural deterioration.

If you’re seeing damp patches, cold slabs, salt blooms on floors, or you’re planning a conversion and want to prevent future moisture issues, this could be the ideal moment to act. Book your damp proof membrane assessment with us today and let us protect your property’s fabric and value.

Our Damp Proof Membrane Services

Full Diagnostic Survey

We assess the specific moisture ingress path (wall, floor or ground) and determine if a DPM is the correct solution.

Floor Slab Membrane Installation

For new build or existing floors above ground we install heavy-duty sheet membranes under or over slabs to block moisture transmission.

Internal Wall Membrane Systems

When moisture is penetrating through walls, we apply studded sheet membranes with integrated ventilation to create a drying cavity and protect internal finishes.

Liquid Applied Membrane Solutions

For complex or retrofit situations we can apply liquid membranes that cure in situ to form a seamless barrier against damp transmission.

Connection with Other Treatments

We integrate membrane installation with other damp solutions (e.g., DPC installation, timber treatment, moisture surveys) where necessary for full-scope protection.

South Coast Coverage & Guarantees

We provide locally responsive service with long-term guarantees and follow-up inspections.
