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® GR is a uniquely formulated synthetic rubber based swellable waterstop. It unites the most desirable characteristics of strip applied waterstops in one product. The initial onset of expansion is delayed for up to three days of exposure to water, after which the swelling begins. Overall expansion is restricted in order to prevent concrete spalling. The Cresco® GR waterstop will maintain its shape and will not be flushed out over time. The proprietary grooved profile improves concrete bond and enhances waterproofing performance. It can be used for waterproofing any static concrete to concrete joint.
Our time tested bentonite type waterstop, Cresco® BT, features a high grade of sodium bentonite and excels in terms of form stability. This general purpose waterstop can be used as the primary joint seal or a redundant secondary barrier in combination with our metal waterstops or the Intec Injection hose system.
