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.

  • Swelltite is easy to install
  • Ready for use and requires no set-up
  • Does not require torching or priming
  • Overlapped seams and mechanical fasteners eliminates installation variables in the field
  • It can be applied in all weather conditions to green concrete 
  • Swelltite is conveniently packaged in easy to handle 1 metre wide rolls
  • The tough geomembrane liner eliminates the need for protection board in some installations
  • Applications include split-slab deck and plaza construction, backfilled concrete foundation walls, masonry block foundation walls, and tunnels
  • Swelltite contains virtually zero VOC
  • Proven effective for split-slab, plaza deck, protected membrane roof and landscaped assemblies
  • Can be installed in temperatures below freezing

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:

  • Below-grade masonry block walls
  • Split-slab Plaza Deck Construction
  • Cut & Cover Tunnels
  • Masonry Block Foundation Walls
  • Concrete Foundation Walls
  • Earth-covered Structures

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.
BRANZ and BBA Appraised

The Volclay Waterproofing System is an approved Alternative Solution in terms of New Zealand Building Code compliance.

ROLL SIZE & PACKAGING: Volclay Swelltite is supplied in 1.0 m x 10.2 m rolls for 10.2 m² per roll.

LIMITATIONS

  • Swelltite should only be installed after proper substrate preparation has been completed and is suitable to receive the waterproofing system.
  • Concrete work should use conventional cast-in-place forms that produce a smooth surface.
  • Do not use stay-in-place concrete forming; use removable forming products only.
  • Do not use product without proper backfill or topping slab confinement.
  • Swelltite is not designed for unconfined above-grade waterproofing applications or subsurface applications that do not provide full confinement coverage.
  • Do not install Swelltite on horizontal plaza deck applications that utilize pavers placed on pedestals. Swelltite is not designed to waterproof expansion joints.
  • Expansion joints require a properly engineered expansion joint sealant product manufactured by other companies (please see: Emseal).
  • Do not install Swelltite in standing water or during precipitation.
  • If ground water contains strong acids, alkalis or is of a conductivity of 2,500 µmhos or greater, submit water samples to the manufacturer for compatibility testing.
  • Consult Allco for special installation guidelines that apply to shotcrete and precast concrete construction.
  • Install Swelltite only in dry weather. Installation should not proceed when work areas are flooded or excessively wet, nor when rain can be reasonably anticipated before Swelltite can be properly covered.

 

Harewood Underpass

Another watertight underpass is completed. The brief was durability for the life of the structure with a requirement to be leak free to maintain the integrity of both the profiled panel façades and the Architectural Coating.
