Cresco

Cresco® GR:

A uniquely formulated synthetic rubber based water stop. 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 water stop 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.

Cresco® BT:

A bentonite type water stop, featuring a high grade of sodium bentonite that excels in terms of form stability. This general purpose water stop can be used as the primary joint seal or a redundant secondary barrier in combination with our metal water stops or the Intec Injection hose system.
