Self Swelling Waterstops
Bentorub
Bentorub is a green, flexible hydrophilic bentonite strip for the sealing of construction joints in concrete. It is made from natural bentonite clay and synthetic rubber. Bentorub is designed for sealing construction joints, cold joints and working joints in concrete, around pipe penetrations, in sewer joints, against slurry walls and sheet piling, etc.
Bentorub has a proven track record in water treatment plants, water purification plants, underground parking lots, water reservoirs, swimming pools, water tanks, metro-works and other concrete structures subject to high water pressure up to 8 bar. The strip can be easily installed by nailing (4 to 5 nails per metre) or glued with Contact Adhesive, Swellseal Mastic or Bentoglue. It is recommended to protect the Bentorub strip using the Bentosteel fixing cage.
Profile size 25mm x 20mm. Roll size 5m. WRAS Approved.
Swellseal Joint
Swellseal Joint is a co-extruded, vulcanised hydrophilic rubber strip used primarily for sealing joints in pre cast elements. It can also be used for sealing construction joints, pipe penetrations and joints in underground pre-cast elements /structures etc. The ridged finish ensures a good adhesion to concrete. Swellseal Joint can be easily installed by nailing (4 to 5 nails per metre) or glued with Swellseal Mastic / Contact Adhesive in horizontal applications.
Profile size 25mm x 7mm. Roll size 10m.
Dual Seal Waterstop
Dual Seal Waterstop is a bentonite / HDPE based waterstop which reacts in contact with water by swelling to form a watertight seal in concrete structures. It can be installed directly onto scabbled surfaces and will swell into honeycombing of concrete or voids up to 12mm deep. Dual Seal Waterstop requires a minimum of only 25mm cover so can be place beyond the outer layer of rebar to protect this layer, rather than be placed in the centre of the construction joint in the traditional manner. Changes of direction and end joints are simply achieved by butting together, no welding or adhesives are required.
Dual Seal Waterstop has been independently tested up to 30 metre head of water, and has full WRC approval for use with potable water. Dual Seal Waterstop can be applied to green concrete and in damp conditions.
Profile size 25mm x 7mm. Roll size 8m.
