CreteSafeB-250®-is a water based elastomer modified bitumen applied as a dual fluid system with an inorganic salt solution. This coating functions as a high quality, protective membrane providing exnt protection for concrete surfaces from water penetration, salt or other chemical attack. It is highly elastic and will bridge small cracks that appear in the concrete. It is seamless and fully adhered to the surface so no water can get behind the coating to attack the concrete.CreteSafe B-250® is used wherever concrete needs to be protected from the effects of water, salt or chemical damage both above and below grade. Special technological devices needed for that appliance.
