Protective Waterproof Coatings & Membranes
University of Queensland Rain Water Tank
The University of Queensland’s main campus at St Lucia is set on a 114-hectare site bounded on all sides by the Brisbane River, seven kilometres from the Brisbane CBD.
With approximately 40,000 students and 7,000 staff the University is one of Australia’s finest and most prestigious universities.
Christopher Contracting Pty Ltd were engaged by Watpac to apply specified VersEseal Liquid Rubber coating to a rain water tank on level 7 in UQ’s St Lucia campus totalling 100sqm in surface area. The concrete floor and walls of the tank consisted of many penetrations, z-bolts hole and construction joints.
Christopher Contracting engaged VersEseal Liquid Rubber contractors to undertake all supply and application work for the coating of the tank. This involved using VersEseal Liquid Rubber Quickset and Rapid Build products to waterproof the tank against leaks. VersEseal Liquid Rubber Rapid Build was used in conjunction with geotextile fabric to repair and seal the tank’s construction joints as well as floor to wall joints. VersEseal Liquid Rubber Quickset was then progressively applied, using an airless spray pump, to coat parts of the concrete floor and all the tank walls to provide a final waterproof seal.
The final product provided the client with a completely waterproof, durable and highly flexible membrane that is far superior in comparison to competing products due to its excellent adhesion and elastomeric properties for the concrete floor and walls.
VersEseal Liquid Rubber Quickset and Rapid Build offered Christopher Contracting and UQ the following distinct advantages over competing products:
- Excellent adhesion to dated concrete surfaces
- Excellent resistance to temperature variations
- Excellent sealing properties (leak proof)
- Efficient and short application time (per m2) and short curing time
- Reduction in tank downtime (during and post application)
- Environmentally friendly, non toxic with no VOC’s
- Certified to AS/NZS 4020:2005 for Potable Water
- Excellent elongation and recovery properties (over 850%)
