Xypex Kuniseal Waterstop C-31 DS
Kuniseal C‑31 DS is a self‑adhesive bentonite clay swelling waterstop engineered for effortless installation in cast‑in‑situ concrete joints. Once in place, it expands to seal both vertical and horizontal construction joints, foundation connections, and penetrations—effectively blocking moisture ingress even under marine conditions. Its delayed-swell technology and high-durability formula ensure consistent, long-lasting performance without stressing the surrounding concrete.
