Understanding Type A and Type B Waterproofing — and Why It Matters

Below-ground waterproofing is one of the most critical elements of a building’s long-term performance. That’s why understanding strategies - particularly Type A and Type B protection - is increasingly important for designers, engineers, and builders across New Zealand.

A complete below-ground system: Allco adds new type A and type B waterproofing solutions

We’re excited to share two major developments that strengthen our below-ground waterproofing offer: the addition of two well-known membranes in New Zealand—Bituthene® and Preprufe® from GCP. We’re also expanding into a new product category with Centrament Proof 10 (CP 10) from MC-Bauchemie, our first concrete admixture solution.
