CrescoŽ expanding waterstops

Waterstops to seal construction joints

The Cresco® range of expanding waterstops is used to seal construction joints, especially those with complicated geometrical joint shapes. Cresco® waterstops are fixed in position using nails or glue. All waterstops have excellent resistance to chemicals. A watertight seal is achieved when the waterstop swells after water ingress into the joint.

 Cresco BT

  • Cresco® BT is a sodium bentonite based expanding waterstop that expands in a controlled manner by up to approximately 350 % whilst maintaining its shape.
  •  Cresco® BT is suited for use in areas with wet and dry cycles and can be used under adverse weather conditions.

Cresco® PU expanding waterstop

  • Cresco® PU is a polyurethane based expanding waterstop that expands in a controlled manner. Due to its specific material properties, 
  • Cresco® PU is also suited for use in areas with wet and dry cycles.

Cresco® AC expanding waterstop

  • Cresco® AC is an acrylatepolymer based expanding waterstop that expands in a controlled manner to ensure a tightly sealed concrete construction joint. 
  • Due to its low profile with a 6 mm thickness, unintended spalling of the concrete surface due swelling pressure is avoided.

Intec® Combi

  • Intec® Combi is a combination of an expanding waterstop with an injection hose and has been developed for simple and secure sealing of construction joints. 
  • This combination between expanding waterstop (primary seal) and injection hose (secondary seal) ensures excellent watertight joints under all conditions. 
  • Subsequent injection of the hose is only necessary if leakage occurs.
  • Metal mesh not standard
