ACQUASHIELD-WS is a well-developed swellable bentonite waterstop with a patented rain protection layer which is economic and reliable. It is used for waterproofing construction joints which are permanently or only temporarily subject to ground or surface water infiltration. AQUAFIN-CJ4 will create a watertight seal in construction joints subjected to water pressure of up to 7 bars. Due to the patented rain protection, ACQUASHIELD-WS can even be installed during rain without causing construction delays.
