Waterstop-RX is an active bentonite/butyl-rubber based waterstop designed to stop water infiltration through cast-in-place concrete construction joints by expanding upon contact with water to form a positive seal against the concrete.
The key to the effectiveness of Waterstop-RX is it’s 75% sodium bentonite content which provides superior expansion to seal cracks and fill small voids. Waterstop-RX is a reliable and cost-effective solution to preventing water infiltration through concrete joints.
Waterstop-RX offers a low cost opportunity to enhance the performance of a sound external waterproofing system, by sealing the areas of highest probability of water infiltration through the concrete, and should therefore be implemented as part of the waterproofing design.
Waterstop-RX can also be refereed to as a swellable water bar when being used in projects involving new to old slabs joins.
Three different sizes and profiles are available to match to your specific project needs: RX-101, RX-101T, and RX-102.
APPLICATIONS: Applications include both vertical and horizontal non-moving concrete construction joints, new to existing concrete construction, irregular surfaces, and around through-wall penetrations, such as plumbing and utility pipes. Additionally Waterstop-RX can seal around concrete pilings and steel H-piles passing through the slab. Waterstop-RX works in both continuous hydro-static and intermittent hydro-static conditions
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.

Due to the location of the building in the Wynyard Quarter there is a high concentration of contaminants, high water table and saline. A waterproofing membrane was required not only to handle hydrostatic pressure but also to act as a vapour barrier protecting indoor air from potential ingress of hydrocarbon vapours.READ MORE
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.READ MORE
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 self-sealing properties of the Volclay Swelltite Sodium Bentonite Membrane made an ideal choice for this & other high profile earth covered structures. With the minimum confinement criteria of 300mm earth cover (over the Swelltite) achieved; this application was very straight forward and has gone on to showcase in several...READ MORE
The rear Southern courtyard, built in 1960, provided the space for six new floors. The courtyard was excavated to a depth of 12 metres to allow two basement levels. Above ground, four new levels were contained in a ‘bowl’ structure and topped by a copper and glass dome.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
Tanking to footings and precast panel retaining walls, lift pit and storage areas, plaza deck, roof and guttersREAD MORE
The building of the three level basements required excavation down to 11 metres below street level and eight metres below sea level. The site is on reclaimed land. Ground contamination from its former use as a petrol station was mitigated with the introduction of sediment control and filter pumping systems...READ MORE
As the plaza deck waterproofing was to be staged over a number of months with tight construction deadlines a membrane that was able to placed and detailed in virtually any weather was a must. The membrane was also required to be tough and self healing if damaged by construction site...READ MORE
