Swellstop  is a sealant tape which swells on exposure to water to seal gaps in concrete joints. It is a butyl polymer based waterproofing tape. Swellstop can be used for many types of poured-in-place concrete jobs and below grade precast concrete applications. Swellstop strongly adheres to clean, dry concrete. It is designed for stationary joints and can be applied in all types of weather and a wide range of temperatures. Swellstop will stay pliable in cold weather, without hardening or shrinking. In hot weather, Swellstop does not become spongy.
