Introduction
Preprufe is a high-performance, pre-applied waterproofing membrane specifically designed for below-ground construction where reliability is paramount. Ideal for underslab and blindside applications, it is especially well-suited to zero-boundary sites common in high-density developments.
Unlike traditional membranes, Preprufe forms a permanent adhesive bond with freshly poured concrete, effectively eliminating water migration between the membrane and structure—even under significant hydrostatic pressure. This makes it a preferred solution in complex civil infrastructure and commercial foundations throughout New Zealand.
To perform as intended, Preprufe must be installed on a clean, properly prepared substrate and applied by trained professionals. Its proven success across New Zealand’s most challenging tanking environments makes it a trusted choice for specifiers seeking long-term protection below ground.
Considerations
It is essential to create a sound and solid substrate to eliminate movement during the concrete pour. Substrates must be regular and smooth with no gaps or voids.
Inspect the membrane before installation of reinforcement steel, formwork, and final placement of concrete. Repair any damage using approvedtechniques.
Corners, pipe penetrations, and terminations must be carefully sealed with compatible accessories or liquid membranes to ensure continuity.
May only be installed by approved Nuralite applicators
