Waterproof Membrane Systems & Applications

We install professional waterproof membranes for basements, roofs, wet areas, and below-ground structures using liquid-applied and sheet membrane systems.

Liquid-Applied Membranes

Cold-applied liquid waterproofing that cures to form seamless, flexible membranes. Ideal for complex details, irregular surfaces, and areas requiring perfect continuity without joints.

HDPE Sheet Membranes

High-density polyethylene sheet membranes for basement tanking and below-ground waterproofing, providing robust protection against hydrostatic water pressure with long-term durability.

Bituminous Torch-On Membranes

Multi-layer torch-applied bituminous membranes for flat roofs, podium decks, and external waterproofing, creating durable barriers resistant to UV, root penetration, and mechanical damage.

GRP Fibreglass Systems

Glass-reinforced plastic (GRP) resin systems for balconies, walkways, and wet areas, providing monolithic waterproof surfaces with excellent durability and aesthetic finishes.

Single-Ply Roof Membranes

EPDM, PVC, and TPO single-ply membranes for flat roof waterproofing, offering lightweight, long-life solutions with heat-welded seams and excellent weather resistance.

Tanking Membranes

Type A barrier protection membranes for basement waterproofing to BS 8102, including gas-resistant membranes for contaminated land and radon protection applications.

Membrane Installation Process

01

Surface Preparation

Substrates are cleaned, repaired, and prepared to receive waterproof membranes. This includes crack filling, levelling, priming, and ensuring surfaces are dry and free from contamination.

02

Detail Treatment

Critical details like upstands, penetrations, corners, and joints receive specialist treatment with reinforcement strips, flashings, and primers to ensure waterproof integrity at vulnerable points.

03

Membrane Application

Waterproof membranes are applied according to manufacturer specifications - liquid systems by roller/spray, sheet membranes by torch-on or adhesive bonding, with proper overlaps and sealed joints.

04

Testing & Protection

Completed membranes are flood-tested or electronically tested for continuity, protected with screed, insulation, or protective layers, and certified with manufacturer-backed guarantees.

Frequently Asked Questions

How much does waterproof membrane installation cost?

Membrane costs vary significantly by type, area size, and application. Liquid-applied membranes typically range from £25-£60/m², sheet membranes £30-£80/m², and GRP systems £80-£120/m² including preparation and detailing. Complex areas with multiple penetrations cost more than simple flat surfaces.

Which waterproof membrane is best for my application?

The optimal membrane depends on substrate type, exposure conditions, accessibility, and performance requirements. Basements typically use HDPE or liquid membranes, flat roofs use torch-on or single-ply systems, balconies use GRP or liquid membranes, and wet rooms use tanking membranes. We assess your specific situation and recommend the most suitable system.

How long do waterproof membranes last?

Properly installed membranes have long service lives: liquid-applied systems 15-25 years, HDPE sheet membranes 25-50 years, GRP fibreglass 20-30 years, and single-ply roof membranes 20-40 years. Many systems come with manufacturer guarantees of 10-25 years when installed by approved contractors.

Can waterproof membranes be installed over existing surfaces?

Yes, many membrane systems can be applied over existing substrates if properly prepared. Old failed membranes may need removal, but sound concrete, screed, or existing waterproofing can often be overcoated with appropriate primers and preparation. We assess substrate condition and recommend the best approach.

Do waterproof membranes need maintenance?

Most membranes are low-maintenance once installed. We recommend bi-annual inspections of exposed membranes (roofs, balconies) to check drainage outlets remain clear, no mechanical damage has occurred, and flashings remain watertight. Below-ground membranes require minimal maintenance once protected and covered.
