Sepatak SWS Waterstop

High swelling synthetic rubber hydrophilic waterstop

Description: Sepatak Swelling Waterstop Strip (Sepatak SWS) is a synthetic rubber waterstop specially designed for waterproofing construction joints in concrete construction. Sepatak Swelling Waterstop swells up to 1000% of its original volume to seal the construction joint and stop water. Suitable for use with regular ground water as well as salt and sulfate contaminated water, Sepatak is extremely durable and will not deteriorate over time, time, even when subjected to repeated wetting and drying cycles.
