Sika Hydrotite CJ-0725-3K-ADH – 32.8' Expandable Adhesive-Backed Waterstop
Sika Hydrotite CJ-0725-3K-ADH is a high-performance, adhesive-backed, co-extruded hydrophilic waterstop engineered to seal construction joints against water ingress. Supplied in a 32.8-foot roll, this profile expands up to eight times its original volume when exposed to moisture, forming a reliable compression seal within cast-in-place concrete joints. Constructed from modified chloroprene rubber, it features a directional expansion profile with a delayed swell coating to ensure proper concrete cure before activation. This profile offers easy "peel-and-stick" installation, excellent durability, and is NSF/ANSI 61 approved for potable water structures.
