Water-activated sealant

Our water-activated sealants are active seals, they expand on contact with water. Other products available in the market only provide passive solutions that slow down water infiltration, but never eliminate it fully. With passive solutions, water always finds its way in somehow!

How Our Water-activated sealants work

Water comes into contact with the BeSealed® seal. The water-activated sealant expands and exerts an extremely high force on the surrounding concrete. This creates an exceptionally good seal that can withstand hydrostatic pressures of up to 6 bar. This is far higher than a regular rubber seal can achieve. The water-activated seal is also self-correcting, i.e. it compensates for any roughness or imperfections in the concrete's surface.

Twenty-Five Years of Experience in water-activated sealants

BeSealed® has been producing Bentobar+, a self-expanding, bentonite clay / butyl rubber strip for sealing construction joints, for twenty-five years. Drawing on many years of construction industry-related experience and expertise, we developed a water-swellable compound based on a synthetic rubber. This compound forms the basis for our hydrophilic waterstopsSealing Plug, Sealing UFO, Sealing Connector and Polybar+ self-expanding sealing joints.

BeSealed® – A Response to Market Demand

The BeSealed® water-activated sealants came about as a response to market demand. Previously, there had never been a reliable solution for sealing formwork spacers in concrete structures.

Spacers were sealed using mechanical systems that were often installed incorrectly. Alternatively, silicone or polymer components were used that required some form of finishing or after-treatment. Drawing on our close ties with the construction industry, we developed a quick, efficient and money-saving solution – the Sealing Plug.

Although initially only intended for the construction industry, our water-activated sealants have become indispensable for a whole range of sectors including the sanitary, tunnelling and oil & gas industries.
