Liquid Roofing and Waterproofing

The world’s leading cold liquid applied waterproofing system

KEMPEROL^® is a complete resin-based liquid waterproofing system. Applied wet-on-wet, KEMPEROL^® bonds directly
to virtually any substrate to provide a seamless, elastomeric, UV-stable membrane that cannot delaminate. This
offers distinct advantages over partially bonded, layered liquid, sheet membrane, or hot-applied materials.

The key to the exceptional performance of KEMPEROL^® waterproofing membranes is the technically superior resin formulation. This is the result of decades of research, chemical engineering and development by a company whose resources are 100% focused on providing liquid waterproofing and surfacing solutions.

New build, flat roof repair and refurbishment

Whether new build, full roof refurbishment or repair, we are able to offer reliable long term protection that you can specify with complete confidence - whatever the substrate or application.

The waterproofing components - one, two or three-part resins - saturate a polyester reinforcement fleece which is immensely strong yet flexible, durable and tear-resistant.

Most liquid-applied systems offer just one resin - a single solution whatever the application. At KEMPER SYSTEM we have a range of dedicated resins, each developed to optimise waterproofing performance under different conditions and specific substrate applications. And unlike multi-layer coating systems, the use of the reinforcement fleece provides a clear visual quality assurance indication that the correct membrane thickness has been achieved. Our three most popular resins are described in more detail below:

Kemperol^® V210

Kemperol V210 is a 3-component, polyester-based system that forms a permanently elastic, seamless, yet highly permeable membrane. Extremely durable and tear-resistant, it can accommodate structural details and penetrations without the need for additional mechanical fixings. Read More

Kemperol^® 2K-PUR

Kemperol 2K-PUR is solvent and odourless liquid waterproofing. It is ideal for use on sustainability based projects or sensitive occupied buildings where solvent-based products would be disruptive. Read More

Kemperol^® 1K-PUR

Kemperol 1K-PUR, ready to use straight from the can, forms a permanently elastic, 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, terraces and patios. Read More
