High Wear Resistance | Flexible Design

Polyurethane is a highly versatile polymer, formed by the combination of two chemicals, polyol and isocyanate. Being able to mix the ratios of these chemicals, plus the addition of catalysts, is what makes polyurethane so versatile.




Pacific Urethanes’ waterproofing is found in a multitude of applications, such as:

  • Protecting metal structures, bridges, storage tanks, pipes, and coating equipment
  • Waterproofing roofs, foundations, decks, and walkways
  • Waterproofing and protecting polyurethane and EPS foam
  • Water retention or decorative ponds water features
  • Waterproofing materials used in water parks and recreation facilities, including natural swimming ponds

Waterproofing for both domestic and commercial applications.


Polyurethane waterproofing solutions provides a flexible, tough, resilient monolithic membrane across a vast array of water, chemical and abrasive environments. Our systems provide high-performance solutions for industrial, corrosion and waterproofing applications providing long-term asset protection.


Polyurethane spray waterproof coatings are typically used as a coating or liner in

  • Slurry tanks
  • Water tanks
  • Secondary containment
  • Waste-water management applications


Pacific Urethanes formulates & supplies polyurethane waterproofing systems that are used all around Australia.

High Strength | Fast Reactivity |Impact Resistant | Waterproofing Membranes

UrePac® Spraycast elastomers are polyurea or urea/urethane hybrids that react within a few seconds once dispensed.

UrePac® Spraycast systems produce tough elastomeric waterproofing membranes/hard coats with high elasticity or rigidity, excellent abrasion resistance, high tensile strength, high resilience, excellent chemical resistance and low temperature resistance.

UrePac® Spraycast 10 95
