Volclay Waterstop RX
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.
- Waterstop-RX 101 is the largest profile with a rectangular cross section of 25 x 19 mm. Requiring only 75 mm of concrete coverage. Roll length 5Lm per roll.
- Waterstop-RX 101T is a 31 x 12 mm trapezoidal shape profile. The patented trapezoidal shape of RX-101T distributes the expansion pressures over a greater area and the reinforcing scrim provides additional product stability when concrete is placed. Requiring only 75 mm of concrete coverage. Roll length 6.10Lm per roll.
- Waterstop-RX 102 is a half-round profile measuring 19 x 9 mm. Requiring only 50 mm of concrete coverage. Roll length 10.2Lm per roll.
- Easy to Install – Waterstop-RX can be installed by one person
- Positive Seal – Waterstop-RX swells and forms a positive seal.
- No Special Transition Parts – Waterstop-RX does not require special cross, corner, or “L” parts to transition from horizontal to vertical.
- Safe – Waterstop-RX is non-toxic and requires no special handling.
- Flexible – Waterstop-RX has excellent flexibility so it can be installed around irregular penetrations like steel H-Piles.
- New-to-existing Concrete – Installs without chipping or saw-cutting existing concrete
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.

LIMITATIONS
- Waterstop-RX is not a self-adhering product. CETSEAL or Masonry Nails are required to secure Waterstop-RX to concrete, metal, or PVC (Pipe) surfaces (fasteners can be used in conjunction with CETSEAL).
- Waterstop-RX is not designed, nor intended to function as an expansion joint sealant. For precast concrete applications, contact manufacturer for product suitability and for any special installation requirements. Waterstop-RX products are designed for structural concrete with a minimum of 20N/mm2 3,000 psi compressive strength.
- Waterstop-RX 101 and RX-101T require a minimum of 75 mm (3”) of concrete coverage.
- Waterstop-RX 102 requires a minimum concrete coverage of 50 mm (2”).
- Waterstop-RX should not be pre-hydrated by being subjected to submersion or remain in extended contact with water prior to encapsulation in concrete.
- In conditions where severe ground water chemical contamination exists, or is expected, consult Allco for product chemical compatibility information

WQIP Building
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.

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.

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.
