Liquid Applied Systems (PMMA)

Different systems explained

PMMA - Poly (methyl methacrylate) - is a fast curing seamless acrylic resin with crack-bridging and joint-bridging characteristics that is able to withstand mechanical stresses, making it one of the best waterproofing systems the market has to offer.

  • WESTWOODS (PU & PMMA)
  • WIDOPAN (PU & PMMA)

PU – Poly (urethane) - single component moisture and air cured polyurethane liquid membrane that is easy to apply over existing roofing systems to create a durable and seamless waterproof layer. Its formulation allows a, fast curing, bubble free, single coat application, seamless, roofing system to be created.

  • MARIS-POLYMERS
  • ICOPAL - ELASTOFLEX

Roof surfaces are subject to continual attack from the weather and from environmental pollution. During the lifespan of a roof the surface is subjected to continual movement and degradation, which if left unchecked, will lead to premature roof failure.

PMMA and PU manufacturers produce a range of seamless liquid applied waterproofing systems which have been proven in virtually every possible roofing situation. They provide excellent durability and are used throughout the world for full roof coverage on all types of roof, designed for use on both new build and refurbishment projects. Due to the ease of application, particularly around difficult details like penetrations, it certainly makes it the system of choice for complex waterproofing projects.
