Swellable strips

Bekina® BeSealed has been producing Bentobar+ for 25 years, a swellable strip based on bentonite clay and butyl rubber for sealing construction joints. Based on this knowledge and expertise in the construction sector, we also developed a water-swellable compound based on synthetic rubber, which forms the basis of our revolutionary Polybar+ swellable strip. We also have the Sealing Inserts from Bekina BeSealed. These special swellable strips are designed for waterproofing prefabricated segments and tunnels.
