Installation Procedure
HYDRATECH HYDRATITE™ SYSTEM
- HydraTite Internal Joint Seal is a mechanical, trenchless remediation for repair of pipe joints.
- The HydraTite system consists of a proprietary rubber seal which spans the joint and is held in place by stainless steel retaining bands in either side of the joint.
- These retaining bands are expanded and locked in place using a wedge lock design which forms an air tight clamp around the joint eliminating all infiltration and exfiltration.
- Each HydraTite seal is designed and custom made for each application to ensure complete compliance with project specifications.
- The HydraTite System is a recognized method of joint repair by AWWA manual M28

DESIGN FLEXIBILITY
WIDTHS • The HydraTite seal is available in three widths:
| STANDARD |  |
| EXTRA-WIDE |  |
| DOUBLE-WIDE |  |
RUBBER - The Seal is supplied in either EPDM or Nitrile. The EPDM is used in applications for potable water, waste water, and sea/brackish water. The Nitrile seal provides superior resistance to gas, oil, and petroleum based reagents making it ideal for natural gas applications.
STEEL - The retaining bands are manufactured to project specifications using either carbon steel, 304 stainless steel, 316L stainless steel or AL-6XN.
RETAINING BANDS - The retaining bands can be supplied as one piece or multiple pieces to accommodate entry restrictions. Systems can also be designed that incorporated extra retaining bands to provide additional support
DIAMETERS - The HydraTite System can accommodate pipe diameters from 18 inches to 218 inches.
BACKING PLATE - A stainless steel backing plate can be incorporated behind the seal to provide support when spanning voids in the pipe wall. This design is utilized in the remediation of expansion joints, sealing off abandoned laterals, and the repair of deteriorated joints.
INTERLOCKING - The patented sleeving design allows for the interlocking of multiple seals. This design provides a means by which to line long lengths of pipe to remediate axial as well as circumferential defects.
HydraTech’s engineering staff designs each HydraTite system to ensure conformance for all project specifications. Each HydraTite seal is then custom made per the design specification. The HydraTite System offers the design flexibility needed to ensure the ideal system is utilized for each installation.
