Sealing cord Bentonite (sqare)

Sealing cord Bentonite

Hhydrophilic bentonite WaterStop gives effective protection against water that penetrates concrete joints including high hydraulic pressure. In contrast from the PVC WaterStop which functions passively blocking the migrating water, bentonite WaterStop reacts with water and swells. The characteristics for swelling allow it to inject itself in the concrete joints, this way it eliminates the migrating water to the joints. Bentonite WaterStop tapes are easy to install and don’t need to be fixated before installment. The tapes are installed via steel nails or special glue.
