KingSwell Seal is a grey, elastic water-swellable paste which is applied like a sealant. The hydrophilic properties of KingSwell Seal 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.
Applications
Sealing around pre-cast segments
Sealing between rough surfaces, e.g. slurry walls and concrete slabs
Sealing around H-beams and other penetration through concrete structures
Sealing around conventional rubber and plastic waterstop to provide belt and braces seal prior to concrete pour
Advantages
Fast curing – Enables early concrete pour and rapid return to service
Excellent seal on rough concrete: Gives improved water tightness
Excellent adhesion – Quick and easy to apply to a variety of damp and uneven joint surfaces remaining firmly in place during concrete pour
Water swellable – Expands by 100% producing a watertight compression seal
Durable – Excellent wet/dry cycling retaining elastic character and swelling performance due to high tolerance of the cementitious environment
