Besaplast sealing bands are used for sealing technical day joints during concreting as well as expansion joints in concrete and reinforced concrete structures. They are a passive barrier for penetrating water. The effectiveness of Besaplast insulating bands is facilitated by their shape and length of the arms and anchors with ribbed surfaces.
The route that must be traversed by the water to pass around the concreted band arms is greatly increased, and the direction in which it exerts pressure changes often. The achieved 'labyrinth effect' forces a water pressure drop, and in the end, puts a stop to subsequent penetration at the band-concrete joint.
Appropriately selected and concreted Besaplast insulating band is an effective barrier for groundwater and water under hydrostatic pressure. The broad range of insulating bands allows them to meet all challenges from constructional and architectural solutions and the conditions at the construction site, in terms of structure tightness and planned use.
