Thanh trương nở bentonite swelling waterstop 20 x 15 mm

Product Description

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

• Easy to install by bonding nailing or casting into joint face. 
• Flexible to use in horizontal and vertical joint. 
• Uses butt end joining to create continuous waterstop. 
• Swelling properties unaffected by long term wet/dry cycling.
• Conforms easily to irregular surface.
• Sustains effective seal in wet conditions.
• Non-toxic and require no special handling.

PRODUCT DESCRIPTION

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

tanks.

HYPERSWELL is high performance hydrophilic swelling waterstop. HYPERSWELL is made of high performance modified bentonite strips. 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.

USES & APPLICATIONS

KEY BENEFITS

•   Easy to install by bonding nailing or casting into joint face.

•  Flexible to use in horizontal and vertical joint.

•   Uses butt end joining to create continuous waterstop.

•   Swelling properties unaffected by long term wet/dry cycling.

•  Conforms easily to irregular surface.

•  Sustains effective seal in wet conditions.

•  Non-toxic and require no special handling.

A flexible butyl rubber and swellable clay waterproofing  compound  that  swells  upon  contact with water to form a long-lasting compression seal in non-moving concrete joints. HYPERSWELL requires a 2-inch minimum clear coverage from the face of the

concrete.

INSTALLATION

3.    To join HYPERSWELL along its length or at intersections, simply “cut & butt”, to form a continuous            network.    Do    not    overlap HYPERSWELL.

4.    Use masonry nails for vertical installed or uneven  substrate  at   approx.  300   mm. spacing.

5.    Do not allow HYPERSWELL to be exposed to rain or standing water prior to pouring of concrete.

1.   Ensure surface of construction joint is clean and free of standing water. Loose / flaking concrete or laitance should be removed by “scabbing”. Forming of a chase is not required.

2.   Uncoil length of HYPERSWELL, with release

paper intact, and apply exposed face against concrete,  pushing  firmly  against  release paper to force HYPERSWELL into concrete undulations. When sufficient HYPERSWELL

has been positioned, remove release paper.
