Liquid Waterproofing Systems

Liquifex-Pro

Liquiflex-Pro is a high performance, wet-on-wet, cold applied liquid waterproofing system that is fully reinforced with a polyester fabric. It has significant advantages over conventional liquid roofing systems because it can be applied wet-on-wet, is a single liquid product, fume free and virtually odourless.

Liquiflex-Pro

Liquiflex-Pro has many advantages over traditional types of waterproofing, particularly within the refurbishment sector. As well as being cold applied, Liquiflex-Pro offers a seamless membrane and is ideal for long term waterproofing of awkward roof details such as pipe penetrations, upstands and gutters. These characteristics also make the system a perfect choice for the long-term protection of balconies and terraces and patios.

Liquiflex-Pro will bond to most substrates, allowing its use in many situations without having to remove and dispose of the existing roof covering. This saves time and avoids the cost of removal and environmental issues associated with disposal.

  • Forms a waterproof, seamless membrane
  • Instantly rain resistant after application
  • Cold liquid applied, straight out of the tin

Liquifex-Pro

Installers prefer Liquiflex-Pro because it is extremely convenient. It is a single liquid product keeping waste at a minimum. The benefits of wet on wet mean no need to hang around waiting for it to dry or come back to site several times. With no fumes, it is also safer and more pleasant to work with.

Liquiflex-Pro is a wet-on-wet system, meaning the basic 15 year system can be installed without waiting on build up layers curing.

The main system has a fast fume dissipation rate, but we also offer a low-odour eco version of the system, making it even safe to work with on occupied buildings.
