Sydney Water

Sydney Water is the largest water utility & provides four million people in Sydney, the Illawarra and Blue Mountain regions with storm water, drinking water, recycled water and waste water services.

As an approved VersEseal Liquid Rubber applicator, RMP Abrasive Blasting (RMP) were engaged by Sydney Water to apply specified VersEseal Liquid Rubber Quick Set specification coating to an assortment of reservoirs and tanks totalling 6200sqm in surface area. The reservoirs especially, had severe cracks in both the floors and walls which necessitated repair using a highly adhesive and elastomeric coating.

RMP used VersEseal Liquid Rubber Rapid Build specification in conjunction with polypropylene geo fabric to reinforce all evident cracks in the floors and walls as well as the construction joints. VersEseal Liquid Rubber Quick Set was then applied progressively (using an airless spray pump) to all internal areas of the reservoirs and tanks to a final dry film thickness of 2mm. The final product provided the client with a completely waterproof, durable and highly flexible membrane strong enough to prevent any future leakage.

VersEseal Liquid Rubber membrane is far superior in comparison to competing products, especially for Sydney Water as they were seeking a product that had excellent adhesion and elastomeric properties for varying surface types (steel, concrete and polymer reservoirs/tanks).

VersEseal Liquid Rubber Quick Set and Rapid Build specifications offered Sydney Water and RMP the following distinct advantages over competing products:

  • Excellent adhesion to dated concrete surfaces
  • Excellent resistance to temperature variations
  • Excellent sealing properties (leak proof)
  • Efficent and short application time (per m2) and short curing time
    Reduction in reservoir downtime (during and post application)
  • Environmentally friendly, non toxic with no VOC’s
  • Certified to AS/NZS 4020:2005 for Potable Water
  • Excellent resistance to ultraviolet light
  • Excellent elongation and recovery properties (over 850%)
