BENTO STRIP is a hydro-expansive sealant used for waterproofing horizontal and vertical casting joints below ground.
BENTO STRIP is produced with a particular type of natural sodium bentonite, polymers and additives, which make it compact and suitable to be made also in different sections.
A fundamental characteristic of the BENTO STRIP joint is the high swelling capacity in contact with water. This expansion produces a sealing and waterproofing barrier in correspondence with the sections of the concrete affected by casting construction joints.
