Material: Rubber, Absorbent resin.
Swelling ratio: 250%-600%
Elongation: 400%
Color: Red, black
Hydrophilic rubber waterstop is an absorbent strip used to seal and waterproof concrete joints. It is made of polymer expansion rubber. The synthetic rubber/polymer expansion rubber expands in the joint when exposed to moisture.
It is a new type of waterproof material, water stop, waterproof effect is more reliable than ordinary rubber. In contact with water the waterstop strip will swell approximately 250% -600% of its original dry volume, the expansive clay mass will seal the cracks and small voids in the joint.
◆ Sealing construction joints
◆ Cold joints and working joints in concrete
◆ Around pipe penetrations
◆ Sewer joints
◆ Against slurry walls
◆ Sheet piling
◆ It is designed to seal the opening gap of joints by water absorbing and volumetric swelling.
◆ Good swelling properties even when in contact with sea and cement water.
◆ Excellent physical properties and compression set.
◆ It is flexible enough to follow any corners.
◆ It can swell repeated without losing its properties.
