72 | SECTION Allco Waterproofing Solutions: 50th Anniversary T T Karen Phelps Waterproofing partner marks 50th year Environmental sustainability features prominently in Allco’s offerings. New Zealand-owned Allco Waterproofing Solutions is celebrating its 50th anniversary in 2025, marking five decades of providing comprehensive waterproofing solutions both above and below ground for the country’s construction industry. Allco has built its reputation on delivering complete waterproofing systems that protect buildings from foundations to roof. The company’s expertise spans from below-ground elements, through to advanced roofing solutions. “We’ve been successful for so long, due to quality product, personal service, exemplary support and our ability to be agile and adapt to market needs,” says Cristine Evans, Allco’s marketing manager. “Our robust team and extensive internal knowledge, combined with our large range of products, has resulted in a reputation for truly helping customers.” The company’s comprehensive approach to waterproofing, from early design through to installation, helps it deliver the best outcomes for the built environment. Its below-ground solutions utilise proven systems, including bentonite-based Volclay membranes, bituminous solutions, and specialised damp-proof systems, each selected and tested to suit New Zealand’s unique climate, soil, and seismic challenges. Above ground, Allco’s roofing solutions go well beyond traditional membrane supply. The company brings together certified products, resilient design thinking, and technical partnership to deliver outcomes that meet contemporary architectural demands. Allco’s roofing portfolio includes warm roof systems that integrate membrane, insulation and accessories into high-performing, code-compliant solutions. The company’s ALLTHERM Warm Roofing System places insulation outside the building envelope, eliminating condensation risks whilst meeting H1 requirements across all six New Zealand climate zones. Environmental sustainability features prominently in Allco’s offerings. Its JM TPO membranes are CodeMark certified and tested suitable for potable water collection, supporting environmentally conscious clients that want their buildings to serve multiple functions. Whether it’s a rainwater harvesting system or a remote home relying solely on roof-collected drinking water, Allco’s solutions are trusted to deliver. The company also supports green roof systems that improve stormwater management, biodiversity, and thermal regulation. These living roofs can retain up to the first 20 millimetres of rainfall, reducing runoff by nearly two-thirds, whilst extending a roof lifespan to 40 years compared to 17 years for conventional roofs. Innovation continues to drive the company forward. Allco’s unique hot melt monolithic membrane, Hydrotech, provides seamless waterproofing, ideal for zero fall applications, offering compliant waterproofing performance even on completely flat roofs, while its ALLRITE Recover Roof System enables existing metal tray roofs to be retained and reused as structural platforms for re-roofing systems. Allco’s experience also extends to complex flat areas like terraces and balconies, which Cristine says often suffer from detailing mistakes that compromise performance. Allco continues to expand its CodeMark certifications, currently processing applications for its Casali bitumen membrane range to complement existing certifications for Hydrotech and TPO systems. Cristine says this certification provides building consent authorities with confidence that products meet New Zealand Building Code requirements. Another very important aspect is the support Allco offers, which Cristine says is above and beyond anything else seen in the market. “The Allco technical advisory team provides expert guidance, support and on-site assistance to our approved applicators and main Canterbury’s Commercial Roofing Specialists T: (03) 335 0077 E: office@newfieldroofing.nz Allco Waterproofing Solutions Proud to be associated with QUALITY ROOFING AND WATERPROOFING SOLUTIONS Specialist Roofing | Membrane, Metal, Tile & Shingle Tanking & Underground Systems | Decks & Balconies High Performance Warm & Green Roof Systems Since 2006 021 761 642 | admin@watertightsystems.co.nz | www.watertightsystems.co.nz
