The HydraTite system from HydraTech Engineered Products is a mechanical, trenchless remediation for leaking pipe joints consisting of a rubber seal that spans the joint and is held in place by stainless steel bands on either side of the joint. The retaining bands are hydraulically expanded and locked in place, eliminating all possibilities of infiltration or exfiltration. 513/827-9169; www.hydratechllc.com.
