Thanh trương nở bentonite swelling waterstop 20 x 10 mm

HYPERSWELL is high performance bentonite swelling waterstop. The swelling action is the result between water and hydrophilic groups which are part of the HYPERSWELL molecular structure. Expansion of the waterstop creates a positive seal against the face of the concrete joint and prevents the water entry into the structure through the protected joint.

HYPERSWELL is used primarily for foundation walls slabs, slabs-on-grade, precast wall panels, manholes, pipe connections, box culverts, utility and burial vaults, wet wells, and potable water tank.

Product Benefits

• Swelling properties unaffected by long term wet/dry cycling.
• Conforms easily to irregular surface.
