At Bituminous Membrane Waterproofing, we specialise in protecting structural surfaces with high-performance bitumen-based systems. These membranes, applied by torch or cold adhesion, form continuous, durable barriers that defend against moisture intrusion.

Whether applied to flat roofs, podiums, balconies, or below-grade foundations, our installations across the UK provide robust, certified waterproofing ideal for both residential and commercial settings.

What Are The Benefits Of Bituminous Membrane Waterproofing?

Bituminous membrane waterproofing systems offer long-lasting protection by forming impermeable layers that resist rain, groundwater, and snow. These membranes help prevent water ingress that could lead to corrosion, mould, or structural decay.

Their durability under UV exposure and resistance to mechanical wear make them ideal for high-exposure areas like terraces and low-slope roofs. With strong adhesion to concrete, timber, or metal, they are also suited for complex detailing around flashings, upstands, and drainage points.

How Is Bituminous Membrane Waterproofing Applied?

Bituminous membrane waterproofing is applied through several methods depending on the site and surface:

• Torch-on membranes – Heated and bonded onto the substrate, creating a welded, watertight finish ideal for flat roofs and decks.
• Self-adhesive membranes – Cold-applied peel-and-stick sheets used where torching is impractical, such as near flammable materials or confined areas.
• Primer application – Applied beforehand to ensure proper adhesion across the entire substrate.
• Detailing and protection – Flashings, outlets, and terminations are sealed with precision, and finishes like screed, ballast, or paving may be applied.

How Much Does Bituminous Membrane Waterproofing Cost?

Bituminous waterproofing costs between £20 and £40 per m², depending on whether the membrane is torch-applied or self-adhesive.

Complex detailing—such as pipe penetrations, corners, and upstands—may raise costs to £40–£60 per m². Final pricing depends on surface condition, accessibility, membrane type, and required finishes.

What Materials Are Used For Bituminous Membrane Waterproofing?

These systems use bitumen-based membrane waterproofing with reinforcements and surface treatments designed for strength and environmental resistance, including:

• SBS- or APP-modified bitumen sheets – Flexible and durable materials ideal for varied climates and structural movements.
• Polyester or fibreglass reinforcement – Enhances tensile strength and puncture resistance.
• Mineral or reflective surface finishes – Provide UV protection and reduce heat absorption.
• Primers and sealants – Ensure full bonding and watertight seams, especially at joints and critical transitions.

How Long Does Bituminous Membrane Waterproofing Last?

When correctly installed, bituminous membrane waterproofing has a service life of 20 to 30 years, especially with regular inspections and light maintenance.

Periodic debris removal, prompt repair of punctures, and re-sealing of critical areas extend system longevity. Flood testing during and after installation also helps ensure early issue detection and long-term performance.
