High Performance Hydrophilic Swellable Waterstop

SUPERSTOP SW is made of high performance hydrophilic rubber strips. The swelling action is the result of contact with water. Expansion of the waterstop creates a positive compression seal against the face of the concrete joint and prevents water entry into the structure through the protected joint.

Basic Uses

SUPERSTOP SW can be applied against existing concrete and simply installed by nailing or using a hydrophilic adhesive. In contact with water, hydrophilic polymers react and swell by up to 450 – 600% of the original dimensions to form and excellent compression seal.

  • SUPERSTOP SW strips are suitable for installation in low movement construction joints.
  • SUPERSTOP SW is used primarily for tunnels, foundation wall slabs, slabs-on-grade, precast wall panels, manholes, pipe connections, box culverts, utility and wet walls, between old & new concrete and potable water tanks.
