The Enviro HP Series

High Performance Sprayed Elastomers

The practice of ensuring that a structure is waterproof is a fundamental element to the success of any project. Envirosystems offers a complete range of high performing liquid waterproofing membranes that have been used on a variety of major tier one construction projects globally.

The Enviro HP Series consists of a range of premium spray applied polyurethane and polyurea elastomers that offer ultra-fast curing and superior waterproofing properties backed by extended warranties when applied by accredited applicators.

What are elastomeric polymers?

An elastomer is a polymer with a high viscoelasticity that is often interchangeably used with the term ‘rubber’. Thermosetting sprayed elastomers are extremely fast setting and curing (gels in 5-8 seconds), tack free in 30-60 seconds and foot trafficable within minutes.


  • Elastomeric polymer coatings are seamless & provide a robust barrier to water/vapour & physical/chemical attack
  • These coatings are extremely fast track applications
  • Can be applied to a wide variety of substrates
  • High range of service temperatures from -30ºC to +150ºC
  • Good abrasion and impact resistance, yet remains fully flexible
  • Environmentally friendly, 100% solids with a low VOC content
  • Virtually maintenance free
  • Long life expectancy and proven track record
