Roof waterproofing

Why choose liquid applied waterproofing?

Liquid applied roofing membranes are revolutionizing the way we think about roof protection. Offering seamless, flexible, and highly resistant coatings, they ensure complete waterproofing coverage on a wide range of surfaces. The benefits of liquid roof waterproofing extend beyond the initial installation, providing long-term protection that reduces maintenance costs and prevents costly repairs.

Our range of Starflex systems, designed and developed by MPM, offer the perfect balance between innovation, resilience, and durability. With a range of high-performance liquid waterproofing solutions, you can trust that your roof will be fully protected against the harshest weather conditions, from heavy rain to intense UV exposure.

Among their key performance advantages over bituminous sheet membranes:

• Seamless coverage – no lap joints, no thermal weld failures, no seam delamination
• Crack-bridging elasticity – accommodates structural movement without breach
• All-substrate adhesion – bonds directly to concrete, bituminous membranes, metal, PVC, TPO, tiles, and fibre cement
• Fast return to service – rain-safe in as little as 1 hour, walkable in 24 hours
• Low VOC formulations – cold-applied chemistry, no open-flame torching required

Starflex liquid waterproofing systems: our flagship

Starflex Mono

A solvent-based, single-component polyurethane membrane offering superior elasticity and crack-bridging performance. Starflex Mono bonds to concrete, tiles, bituminous membranes, PVC and metal without mechanical fastening, delivering a seamless waterproof flat roof coating on both new build and refurbishment projects.

• Etag 005 / CE 1504 certified
• BBA certified
• CAM compliant
• Asbestos roof overlay approved

Starflex H-Zero

A single-component polyurethane membrane formulated without ADR/IMDG hazardous classification. Starflex H-Zero offers all the performance of a professional liquid-applied roofing system with none of the logistics constraints, making it the preferred choice for distributors and contractors operating across multiple territories.

• No ADR, No IMO classification
• CE certified, BBA approved
• Fully compatible with Starflex system components

Starflex Ultra FR

A single-component polyurea membrane for the most demanding environments. Starflex Ultra FR applies fresh-on-fresh at high film thickness in a single coat, even on vertical surfaces, and is rain-safe within 1 hour. Its exceptional elongation and tear resistance make it the reference standard for industrial roof waterproofing, heavy-traffic rooftops, and exposed flat roofs in severe climates.

• Certified B-roof T4 (fire resistance)
• ETA certified, REACH compliant, CAM criteria
• Up to 30-year proven durability
• Anti-hail tested

Starflex Hybrid

The only liquid waterproofing membrane in its class that can be applied directly onto wet and damp substrates, with no primer required. Starflex Hybrid extends the working season to year-round, eliminating weather-related project delays and reducing downtime.

• No primer on wet or damp surfaces
• Fast cure even at low temperatures
• Aliphatic formulation – UV stable, non-yellowing
• Ideal for emergency repairs in live environments

Starflex One

A water-based, single-component bituminous elastomeric membrane for roofs, terraces, and foundations. Starflex One offers outstanding UV resistance and long-term durability on a wide range of substrates, including damp surfaces, without solvents or open flame.

• Water-based, low environmental impact
• Applicable on damp substrates
• UV and weather resistant

Starflex C

A two-component elastic cementitious mortar engineered for continuous waterproofing on both new and existing substrates. Starflex C is the system of choice where a mineral-based solution is required (under-tile flat roof applications, wet areas, pools, and foundations) delivering high crack-bridging elasticity and fast cure even in cold or damp conditions.

• Bonds to concrete, screed, tiles, and masonry
• Rapid cure at low temperatures and on damp substrates
• High elasticity with crack-bridging capability
• UV and weather resistant
• Low VOC, water-based formulation
• CE certified product

Roof waterproofing for every application

Starflex systems are specified and installed across the full spectrum of roofing applications. Whatever the substrate, the exposure, or the project timeline, the range delivers the same outcome: seamless, long-lasting protection with no weak points.

Flat roofs on industrial and logistics facilities
Continuous membrane coverage under high UV, thermal cycling, and mechanical load. No seams to fail, no joints to re-weld. One system that outlasts the maintenance cycle.

Industrial roof waterproofing
Chemical exposure, foot traffic from maintenance crews, roof penetrations for ventilation and plant equipment. Starflex systems adhere to every substrate at the penetration interface, eliminating the gaps where water finds its way in.

New build flat roofs
Direct application over structural concrete deck or rigid insulation board, with no need for mechanical fastening. Fast cure, fast handover.

Refurbishment over existing membranes
Overlay directly onto bituminous membranes, TPO, PVC, metal, and fibre cement without stripping. No demolition waste, no landfill costs, significantly reduced project duration.

Wet and damp substrates
Where traditional membranes require dry conditions and delay the programme, Starflex systems keep the project moving. Application is possible even on damp surfaces and at low temperatures.

Under-tile flat roof and terrace waterproofing
A continuous waterproof layer beneath the tile bed that accommodates structural movement without delamination, on both new construction and refurbishment.
