Building a dam always calls for an impressive feat of civil engineering. And of course, one of the most important aspects of a dam is that it is 100% watertight. To prevent water infiltration and concrete rot in dams, Bekina BeSealed has developed its own rubber compound with a very high expansion capacity. Our active sealing technology ensures that the swellable strips swell automatically when they come into contact with water, thus creating high pressure against the surrounding concrete. In this way, water infiltration is eliminated.
