The DC seal strip is a material made with PVC and a hydrophilic thermoplastic that provides a controlled expansion to the waterstop up to 400% when in contact with water. The DC seal strip produces enough swelling pressure to withstand high hydrostatic pressure, even when exposed to salt water.
- PVC support, ½ x 1 inch sealing, made of hydrophilic thermoplastic reinforced by a semi-rigid PVC extrusion.
- Easy to install
- Resists dislodgment during concrete pouring
- Allows better consolidation of the concrete around the waterstop
- High elasticity and tensile strength
- Resists corrosion
- Swellable up to 400%
- Unaffected by acids, alkali, salts and other chemicals
