HydraTite® Internal Pipe Joint Seal

HydraTite® is a mechanical repair that is installed inside a pipe to seal leaks and rehabilitate aging underground infrastructure without excavation. The system is as simple as it is customizable. The two main components are the rubber sleeve that is pressed against the interior surface of the pipe, and the stainless steel retaining bands that lock the rubber in place, providing a lifetime repair. The rubber and steel are manufactured by HydraTech to meet the specifications of each unique job. The pipe’s size, shape, and material can be accommodated by HydraTite’s incredible flexibility. Below are some project examples of the diversity of applications.

    Who Uses HydraTite?

    Our internal pipe joint seals have been used successfully for over 20 years in pipe joint repairs, pressure pipe repairs, and joint infiltration in drinking water, storm drain sewers, gas pipelines, storage pipelines, distribution pipelines, and power generation pipelines. HydraTite is great for emergency repairs.

      What Can The Seal Do?

      HydraTite® is generally applied in man-entree pipes at joints or points that need repair but is structurally sound. However, the seal has proven itself a reliable solution acting as a replacement for failing expansion joints and as an end seal, terminating liners. In circumstances where a large portion of the pipe is compromised, the HydraTite® seal can be interlocked to stretch beyond the damage. Seals can be manufactured with retaining bands that ship in multiple pieces which can make getting the bands through tight spaces less difficult. The seal sometimes includes a backing band to remediate pressure piping and cooling water expansion joints. Below is a full list of applications.

      Round Pipe Joint Seal
      Repairs deteriorated pipe joints to prevent inflow & infiltration (I&I) and eliminate leaks in pressure applications. Requires man-entry size piping, typically 18” and greater.

      Elliptical Pipe Joint Seal
      Repairs defective joints in gravity flow application to eliminate I&I and prevent sinkhole formation. Custom-manufactured to accommodate man-entry elliptical pipe sizes.

      Box Joint Seal
      Custom-manufactured seal to repair defective joints in box culverts, tunnels, and conduits with rectangular or non-circular cross-sections. Suitable for gravity and pressure applications.

      Liner End Seal
      Designed to span the termination of internal pipe linings and provide water tight seal to prevent backflow between lines and host pipe. Applications in sizes 12” and greater are possible provided access to install does not require man entry.

      Expansion Joint Seal
      Designed to replace defective expansion joints. This design allows for the necessary movement that expansion joints require while maintaining a water or air-tight seal. Designed to be installed without the need to remove the existing expansion joint.
