{"product_id":"gcp-bentorub-waterstop","title":"GCP Bentorub Waterstop","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eGCP Bentorub+ is a permanently active hydrophilic waterstop system for construction joints in concrete sub-structures. The sodium bentonite clay component swells when in contact with water, filling hairline cracks and voids that develop through concrete shrinkage, maintaining a watertight seal throughout the life of the structure. The highly elastic and plastic properties of Bentorub+ also counterbalance initial concrete shrinkage and can fill small honeycombs.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe built-in delayed expansion prevents the strip from reacting prematurely with rainwater before or during installation, giving contractors confidence in wet working conditions. For high-risk situations, Bentorub+ can be used in combination with Infiltra Stop injection grout for added security.
