Product catalog summary
Introduction to Flat Roof Systems
Flat roofs, characterized by a pitch of less than 10°, require effective waterproofing due to exposure to environmental elements. They are commonly used in commercial and industrial buildings due to their economic benefits and additional utility space.

Waterproofing Challenges and Solutions
Flat roofs face challenges such as wind exposure and temperature fluctuations, necessitating reliable waterproofing systems. KEMPER SYSTEM offers liquid resin-based solutions like KEMPEROL®, which provide durable protection even under demanding conditions. These systems are recognized in current standards alongside bitumen and plastic sheeting.

Applications in New Builds and Repairs
Liquid waterproofing solutions are increasingly preferred for new constructions and repairs. They offer long-lasting protection with a certified working life of 25 years. KEMPEROL® systems are lightweight, often eliminating the need to remove old roofing materials, and can be applied without a primer on non-absorbent substrates.

Solvent-Free Systems
KEMPEROL® 2K-PUR is a solvent-free, odorless system that can be applied cold, making it suitable for sensitive environments. It bonds seamlessly with various substrates, providing a permanent, elastic bond.

System Build-Up and Application
The classic KEMPEROL® V 210 system uses a three-step application process: apply the first coat, lay reinforcement fleece, and saturate with a second coat. This method ensures a seamless, durable bond.

Waterproofing Details
Effective waterproofing around roof details is crucial to prevent failures. Liquid applied systems like KEMPEROL® ensure seamless coverage of complex details, reducing weak spots and costs.

Sustainability and Environmental Responsibility
KEMPER SYSTEM emphasizes sustainability, using renewable materials and producing solvent-free systems. Their operations comply with modern environmental standards.

Advantages of Liquid Waterproofing
Liquid systems offer benefits such as no seams, cold application, and resistance to wind suction. They are certified for a 25-year lifespan, UV resistance, and root resistance.

Technical Support and Services
KEMPER SYSTEM provides expert advice, project specifications, and training for contractors, ensuring comprehensive support for their waterproofing solutions.

Flat roofs – a waterproofing challenge A flat roof is not only defined as a roof with no pitch or a pitch of less than 10°: all roofs that require waterproofing are classified as flat roofs. These include domed roofs, sawtooth roofs, VT gabled roofs, “butterfly roofs”, HP shell roofs. Flat roofs unite effectiveness with a wide range of advantages. The fact that they are economic, can be used for additional purposes and provide space for superstructures has made the flat roof the de facto standard for commercial and industrial buildings. Flat roofs are exposed to wind and the elements, making...

New builds As well as being the solution of choice for repairs, experts are increasingly choosing durable, liquid waterproofing solutions from the word go. Longer intervals between inspections, maintenance contracts and an expected working life of 25 years certified according to ETAG 005 provide peace of mind for many years. The permanently elastic membrane selfbonds with most substrates, bridges small cracks and dependably compensates for different material expansion coefficients. Repairs Tackling water damage, repairing substandard refurbishment work, production downtimes or idle periods all...

Combined roofs Modern roofs are increasingly complex, making them difficult to waterproof securely using traditional materials. The advantages of a liquid waterproofing system are unsurpassed, particularly around awkward details and penetrations: longer durability, fewer weak spots, reduced costs and simple, easy to use technology. KEMPEROL® can be combined with almost all standard roofing materials. Watertight details The functionality and working life of any waterproofing system depends to a large extent on the quality of the application around the roof details. Alongside the use of unsuitable...
