Combining the active waterproofing benefits of sodium bentonite with the strength and durability of a thick geomembrane liner. Unlike other membrane systems that require precise installation, SWELLTITE’s reactive bentonite compound can expand to seal small punctures in the membrane. SWELLTITE works by forming a continuous membrane upon hydration with water or vapor. When confined under pressure, the swell is controlled, forming a dense, positive seal against the concrete.
Proven quality and ease of installation have made SWELLTITE a market leader in the New Zealand waterproofing industry. For more than 20 years SWELLTITE has been installed in New Zealand on projects such as split-slab plaza decks, backfilled foundation walls, and cut-and-cover tunnels.
APPLICATIONS: Swelltite is designed for waterproofing below-grade vertical and horizontal structural surfaces, as well as, above grade split-slab construction used with plaza areas, parking garages and sports stadiums. Swelltite is excellent for:
B2 DURABILITY: Performance B2.3.1 (a) not less than 50 years.
E2 EXTERNAL MOISTURE: Performance E2.3.3.
F2 HAZARDOUS BUILDING MATERIALS: Performance F2.3.1. The Volclay® Waterproofing System meets this requirement and will not present a health hazard to people.

The project involved a significant amount of civil works, with retention piling, soil nails and ground anchors used to allow excavation and construction of new basement levels between the heritage buildings. Because it was built into the side of a hill, high hydrostatic pressure was constantly present.READ MORE
The basement parking areas for the building were below sea level and the structure was located close to the boundaries. The site was on reclaimed land within 10m of Waitemata Harbour and the site was contaminated with various oils, petro chemicals & saline.READ MORE
