Megaswell 1020X is a hydrophilic bentonite waterstop strip designed to seal construction joints in concrete structures. Manufactured from premium sodium bentonite and polymer rubber, the strip expands upon contact with water to form an active seal that blocks water ingress through non-moving construction joints.

- Flexible and easy to cut to length
- Suitable for irregular substrates
- Durable and cost-effective
Applications
- Construction joints in concrete walls and slabs
