What Allco Waterproofing Solutions Ltd does

Allco Waterproofing Solutions Ltd is a New Zealand-based private limited company headquartered in Auckland that supplies specialised waterproofing membrane systems and technical advisory services to the New Zealand construction industry. Its product portfolio spans below-ground tanking membranes (Volclay Voltex, Voltex DS and SWR, Swelltite, Coreflex, Preprufe 300R Plus), damp-proof membranes, roofing membranes (Casali bitumen, JM TPO, mastic asphalt / ShieldFLEX), and integrated roofing systems (Warm Roof, Cool Roof, Green Roof, ALLRITE Recover Roof), together with accessories such as Waterstop RX, Bentoseal, Aquadrain, and Centrament Proof 10 concrete admixture. The company holds exclusive New Zealand distribution rights for proprietary global technologies from CETCO/LOREX (Volclay range, Coreflex), Casali of Italy (bitumen membranes), and Carlisle Companies International (JM TPO), and operates an embedded Technical Advisory (TA) team that conducts pre-installation meetings, site inspections and specification writing. As of the latest disclosed data, Allco has accumulated 2,514,073 m² of installed membrane across 6,714 completed projects, 4,817 TA site visits and 11,202 specifications written.

Allco's go-to-market is built on a specification-led, channel-mediated motion rather than direct end-customer sales. The company engages architects, consulting engineers, and main contractors through CPD-accredited presentations, a CAD and document library, presence on the Masterspec and EBOSS specification platforms, and Allco Road Show events; product sales and installations are executed through a nationwide network of 124+ trained and accredited approved applicators, with Allco issuing warranties backed by TA-team oversight. Revenue is generated primarily through one-time sales of membrane products and accessories to applicators and main contractors, supplemented by technical-advisory services, pre-installation meetings, ILD EFVM integrity testing, and warranty programmes. End-customer segmentation spans commercial construction, residential construction, education, healthcare and aged care, and civil infrastructure — evidenced by named projects with Auckland Hospital (ADHB), KiwiRail Hillside Workshops, the University of Auckland's Hiwa Recreation and Wellness Centre, MacMurray Medical Centre (2021 NZ DINZ Best Awards Gold Pin), Antipodean and Marina Terrace apartments, and Aria Bay Retirement Village.

The business is privately held with no disclosed parent company, ownership structure, headcount, or financials. Recent strategic emphasis has been on regulatory positioning (CodeMark certification across the membrane range), sustainability alignment (NZGBC membership, full product EPD coverage), and ecosystem integration (Masterspec, EBOSS, Teulo specification platforms, Teulo partnership), supported by an ongoing investment in the TA team and approved applicator network.
