Celebrating 5 Years with BOINZ and 50 Years in Waterproofing

It’s been five years since Allco Waterproofing first partnered with BOINZ, and what a journey it has been. As proud supporters of building officials across Aotearoa, we were excited to be back at this year’s BOINZ Symposium and even more so as this year Allco completes 50 year serving the New Zealand construction industry.

As a NZ-owned and operated business, we’ve built our reputation on delivering waterproofing solutions that performs combined with unmatched support. We believe we’re more than product suppliers - we’re here to share knowledge, help solve problems, and support the industry with hands-on guidance.

Leading the Conversation at the Symposium

This year, our Product Specialist Chris Ross presented a technical paper titled “Understanding British Standard 8102 – Protection of Below Ground Structures Against Water Ingress.”

In summary, his presentation covered the British Standard 8102:2022 and how it provides essential guidance for designing waterproofing systems that protect below ground structures from water ingress, ensuring long-term durability and safety.

Chris’s talk focused on:

Key updates in BS 8102:2022, the British waterproofing standard.
How it applies in practice, particularly for below-ground construction.
Its relevance to Building Control Officers (BCOs) and Building Surveyors in New Zealand.
Common causes of waterproofing failures, especially from poor design or installation.

His session drew strong interest and positive feedback from attendees. Many appreciated the clarity and practical insights, especially around how early design-stage decisions can make or break a waterproofing system.

Supporting Building Officials Nationwide

Our mission at Allco is to help provide watertight, durable, and safe buildings. We understand the vital role building officials play in approving and inspecting waterproofing details and installations. That’s why we’re committed to being a reliable partner, not just a supplier.

We know that no two projects are the same, that’s why we support our project with technical support, both in-house and on site - from help with drawings, specs to on-site installation advice, our team is always available to ensure everything is fit for purpose and correctly applied.

Proven Systems for NZ Conditions

With 50 years under our belt, we’ve learned a thing or two on what works and what doesn’t in New Zealand’s unique environment. We supply a full range of waterproofing systems - from bentonite-based Volclay membranes to bituminous, TPO, and damp-proof solutions. Each system is selected and tested to suit our climate, soil, and seismic challenges.

A Milestone Year for Allco

This year, Allco turns 50 years old - that’s five decades of serving New Zealand’s construction industry with trusted waterproofing advice and quality systems. We’re proud to say we’ve stayed true to our values - locally owned, industry focused, and solutions driven.

Over the years, we’ve supported thousands of builds across the country, from major infrastructure to multi-res and commercial sites. And we’ve done it by staying close to the people who make things happen: architects, contractors, applicators and of course building officials.

As regulations evolve and projects grow more complex, the importance of robust, compliant waterproofing continues to rise, we believe BOINZ and its members play a key role in lifting standards across the industry, and we’re proud to stand with you in that mission.
