The winners of the Liquid Roofing and Waterproofing Association (LRWA) Awards 2025 have been revealed at a gala dinner in Liverpool.
Attracting more than 400 guests, the event recognised projects across five categories, including the newly introduced Sustainability Project of the Year.
Project complexity, workmanship, problem-solving, and aesthetics were assessed across four categories while the sustainability award was judged on five key themes: Reduced Environmental Impact, Beneficial Social Impacts, Product and System Innovation, Carbon Management and Reduction, and Responsible Supply Chain Practices.
A total of 22 projects made it to the final following an independent judging process, which saw anonymous submissions assessed against strict criteria. As well as a winner of each project category, there was a highly commended accolade for those that just missed out on the top spot.
The event also celebrated the talents of individuals working in liquid roofing and waterproofing.

- Liquid Roofing Project of the Year Under 1000m2 (Sponsored by Instar):
Turner Street Residential: Sika & Permicoat
With tenants facing persistent leaks, a watertight solution was essential for this city centre residential building. The intricate standing-seam metal roof of the former Victorian warehouse features several converging pitches and complex transitions that created challenging areas to waterproof. A polyurethane liquid-applied membrane was installed over the existing substrate, seamlessly covering all angles, curves, and junctions. Adding to the installation challenges, contractors had to control noise levels, adhere to strict safety protocols and overcome logistical constraints. Scaffolding barriers, designated walkways, and restricted access to work areas ensured the safety of residents and the public.
Highly Commended awarded to The Savoy Hotel : Polyroof & Capital Roofing
- Liquid Roofing Project of the Year Over 1000m2 (Sponsored by Recticel):
Center Parcs, Whinfell Forest: Sika & Central Roofing
This complex refurbishment transformed the roof of a sub-tropical, humid indoor swimming pool, eliminating water ingress. A polyurethane liquid-applied membrane was installed over a single-ply roofing system that had reached the end of its design life. The curved roof, rising from 6m to 27m with a 24-degree incline, posed installation challenges in a live and windy environment. Safety measures included fall protection, debris sheeting, and a crash deck. Contractors installed 13 rooflights and incorporated modern corner detailing to enhance durability and energy efficiency. Adaptive problem-solving, night shifts, and rope-access technicians contributed to the project’s success.

- Liquid Roofing Project in a Buried Application (Sponsored by Quantum Insulation):
Google KGX1: Lindner Prater & Radmat
Known as a ‘landscraper’ for its unique horizontal design, this building features a cascading 300m-long roof spanning 10,000 sq. m. Extensive planting, landscaped terraces, seating areas and a 200m running track provide outdoor amenities. A hot melt waterproofing system with XPS insulation was installed across the vast roof space and to provide robust protection for slopes and staircases in a building maintenance unit zone. The green roof was also integrated into this area. Additionally, liquid waterproofing was installed in confined plenum areas, essential for ventilation. The building’s city centre location in King’s Cross required strict traffic, delivery, and safety management, adding to the project’s complexity.
Highly Commended awarded to Marylebone House: Proteus Waterproofing & Essential Building Services
- Liquid Waterproofing Project of the Year (Sponsored by Polyfoam XPS):
Swan Walk Car Park : Triflex & Rateavon
A waterproofing, surfacing and protection system was required for this 900-space car park serving a popular shopping centre 24 hours a day, seven days a week. The existing coating was removed, revealing extensive concrete screed damage and water ingress across the 4,550 sq. m external deck. A former contractor had left the substrate surface deeply scored, adding to resurfacing challenges. Extensive condition mapping enabled targeted repairs, removing the need for a full re-screed. Failed screed areas were cut out and replaced followed by the installation of a rapid-curing PMMA-based system. Emery aggregate provided a skid inhibiting finish while levelling the surface.
Highly Commended awarded to The Thistles Car Park: Triflex and McConnell
- Sustainability Project of the Year (Sponsored by Buzon):
90 Long Acre : MAC Roofing & Contracting and BMI
The redevelopment of this office building retained over 80 per cent of the original structure, reducing embodied carbon by 50 per cent compared to a new build. A green roof system features a London wildflower seed mix with 25 species that mimic the region’s natural plant life. On level nine, a blue roof was installed with a wildflower seed mix suitable for integration with solar panels. With certifications like ISO 14064-1 (Net Carbon Zero) and smart waste tracking, contractors monitored carbon emissions, waste, materials, and energy use throughout. Social impact initiatives included school visits, career fair participation, and hiring two local trainee site operatives.
Highly Commended awarded to 40 Leadenhall and 19-21 Billiter Street: Proteus Waterproofing & ARC Waterproofing
