KEMPEROL Liquid Roofing and Waterproofing
KEMPEROL® The world’s leading cold liquid applied flat roof and 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 flat roof refurbishment or repair, in cold, warm or inverted roof applications, 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 or two 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.

Which is the right liquid roofing and waterproofing system for your project?
A 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. Ideal for new build and roof refurbishment projects.
Beware of imitations – KEMPEROL® V210 was the very first fleece reinforced liquid waterproofing system in Europe and has over 50 years proven effectiveness globally.
KEMPER SYSTEM continues to lead the market with innovative new products and the development of complete solvent-free liquid waterproofing and surfacing systems.
KEMPEROL® 2K-PUR is the first solvent-free, completely odourless, liquid applied, wet-on-wet waterproofing system available in the UK. It is sustainably sourced and ideal for construction projects where environmental considerations are important or where buildings are occupied and work needs to continue without the disruption caused by the fumes from solvent based products.
Do you need to fully waterproof a balcony, walkway or terrace in just one day?
Fast application and rapid curing KEMPEROL® AC Speed is a PMMA resin that can be used for both new build and refurbishment projects over concrete, screed and asphalt substrates.
The new waterproofing system: solvent-free and single-component with very low odour: KEMPEROL® LF is ideal for waterproofing complex details, rooflights, drains and gutters and refurbishing small roof projects and balconies.
This single-component system is based on a silane terminated polymer, is solvent free and virtually odourless - can be used without disruption on occupied buildings.
It has a high humnidity tolerance and can be used on slightly damp substrates. It is also cost effective in that it can be used on most substrates without a primer.
Ready to use straight from the can, this polyurethane resin, when combined with our reinforcement fleece, 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.
Applied underneath tiles to wet room walls and floors with direct or indirect loads. It is ideal for bathrooms as well as for sanitary facilities in hotels, shower installations, utility rooms and washrooms. Solvent-free liquid waterproofing KEMPEROL® 022 has been specially developed for use according to ETAG 022.
A quick emergency solution for repairing leaks. The ready-to-use KEMPEROL® Roofpatch may be applied directly to leaking and damaged areas to effect reliable repairs. Rapid sealing in tried-and-tested KEMPEROL® quality for cracks in bitumen sheets, PVC roofing sheets, concrete, wood, screed and metal.
The main characteristic of REFLECT, the new white coating from KEMPER SYSTEM, is that it utilizes liquid synthetic materials with particular properties to effectively reflect UV and infra-red radiation away from the roof, ensuring the surface temperature remains cooler than when using traditional roofing materials.
KEMPERDUR® REFLECT is a solvent-free reflective coating for roofs. It can be installed quickly and easily to existing KEMPEROL® roofs, and is suitable for overlaying bitumen roofs where the solar reflectance needs to be increased.
So many uses and applications...
Ideal for refurbishment, repair and new build, KEMPEROL® forms a totally seamless, reinforced, UV stable, elastomeric membrane that is ideal for flat and pitched roofs, balconies, terraces, podiums and walkways. Warm roofs, inverted roofs, cold roofs, green roofs and living walls, fountains and water features; and the most complex detailing.
In fact, just about anything you need to waterproof, we have the liquid solution:
Tough, durable and self-flashing, KEMPEROL® fully bonds to virually any building substrate and is flexible enough to accommodate the thermal movement of today’s commonly used materials. Applied direct to the substrate it provides the ideal base layer waterproofing for inverted roof systems.
Terraces and Podiums
KEMPEROL® materials are widely used
to waterproof and surface podium
decks, terraces, walkways and car
parks - demonstrating their exceptional
versatility, durability and reliability.
STRATEX is our integrated warm
roof system. Comprising a vapour barrier, insulation and KEMPEROL®
waterproofing. It will accommodate
maintenance foot traffic and can be
finished with KEMPERDUR® surfacing or decorative landscaping materials where more frequent foot traffic is expected.
Easily applied, KEMPEROL® is a reliable,
long term solution to failed roofs. And
because it bonds directly to existing
materials, costly removal and disposal to landfill is avoided. The option of solventfree, odourless KEMPEROL® 2K-PUR ensures minimal disruption to building occupants.
Pitched and Metal Roofs
KEMPEROL® can be used on profiled
metal, including standing seam roofs.
A reliable and cost effective repair for
metal, copper or lead, it forms a fully
bonded waterproofing membrane that
cures leaks, seals laps and fixings and
rejuvenates the appearance.
KEMPERGRO® brings together a unique combination of recycled, renewable and sustainable components to provide a complete waterproof roofing and green roof system with a single source specification in which KEMPEROL® provides the root resistant waterproofing element.
Penetrations and upstands are easily
waterproofed in situ, becoming an
integral part of the roof membrane
without the need for any additional
mechanical or adhesive fixings.
Valley and Finlock Gutters
KEMPEROL® is ideal for repairing leaking valley and finlock gutters, forming a seamless membrane along the entire length of the channel that seals joints, fixings and penetrations. Outlets are easily waterproofed and incorporated into the seamless membrane. And being flexible it will also accommodate thermal or structural movement.
Parking and Stairways
For trafficked applications, including
both parking areas and stairways,
KEMPERDUR® surfacing can be applied
either direct to the substrate or onto a
KEMPEROL® waterproof membrane; and supplied in a range of anti-slip finishes. KEMPEROL® can also be overlayed by Bitmac and poured asphalt up to +250oC.
KEMPERDUR® surfacing can be applied
onto a KEMPEROL® waterproofing
membrane, giving a highly durable,
slip-resistant finish for balconies and
walkways. Hard landscaping materials
can also be applied, including bedded
tile, paving slabs and decking.
Internal wet rooms, saunas, plant
rooms or bunded areas can be fully
waterproofed with KEMPEROL® and
can be surfaced in a range of finishes or materials. KEMPEROL® 2K-PUR and KEMPEROL® 022 are solvent-free and odourless, so can be applied without disruption to occupants or other trades working on-site.
The integrity and performance of
KEMPEROL® waterproofing materials,
even in permanently immersed
conditions, is highlighted by its suitability for lining water features and fountains.
