Fosroc Supercast SWX

Adam Lowe

Supercast SWX is a grey, elastomeric water-swellable paste which is applied like a sealant. The hydrophilic properties of Supercast SWX display good consistency in swell rate during repeated wet/dry cycling. Expansion of the product on contact with water creates a positive pressure against the faces of the concrete joint, thus preventing the passage of water.
