Compression Joint SX® 1
is a combined compression & swellable waterstop for sealing prefabricated concrete joints. The compression seals located on either edge of the profile are compressed during installation giving rise to a restoring force on the joint flanks. The centrally positioned, chemically swelling waterbar functions as an additional seal.
As soon as the hydrophilic profile comes into contact with water, swelling occurs which seals the joint reliably and permanently.
