This unique combination of precision equipment, finely tuned procedures, highly-skilled installers and the industry’s leading geopolymer, GeoKrete®, allows for project metrics to be monitored in real time to ensure a long-term solution.

Understanding that every project presents unique challenges, the pipe relining system is fully capable of integrating advanced, third-party design and engineering modifications to meet the most stringent structural restoration specifications.

Typical Applications

QLS is typically specified for large diameter pipes, culverts, tunnels and other infrastructure suffering from corrosion, I/I and other problems that could lead to catastrophic failure.

It’s effective on

  • Corrugated metal
  • Concrete
  • Brick
  • Stone
  • Manholes
  • Wet wells
  • Junction boxes

Precision Application to Odd Shapes and Substrates

QLS is an extremely versatile sewer pipe relining system engineered to effectively apply GeoKrete onto a variety of shapes, sizes and surfaces. For angular structures, such as wet wells, junction boxes, box culverts or other infrastructure with edges, corners and obstructions, GeoKrete can be spray-applied and trowel-finished to achieve restored structural integrity, elimination of infiltration and corrosion protection.

The equipment design features advanced technology built into the sled, retrieval system, mixer and pump that allows for a controlled rate of retraction and precision spray application.

Key Features and Performance Benefits
