Thermoform Pipe Lining is an advanced trenchless rehabilitation method used to restore damaged, aging, or failing underground pipelines without the need for excavation. Using a heat-activated, fold-and-form thermoplastic liner, this process creates a brand-new, structurally sound pipe inside the existing host pipe.

The Thermoform liner is pulled into the pipeline in a compact, folded shape. Once positioned, controlled steam or hot water is used to expand the liner to its full round profile, pressing it tightly against the interior walls of the old pipe. As the material cools, it hardens into a seamless, corrosion-resistant pipe with excellent flow efficiency and long-term durability.

Key Benefits:

• No digging required – minimal disruption to property, roads, or utilities

• Seamless, jointless pipe – eliminates leaks and infiltration

• High structural strength comparable to brand-new pipe replacement

• Resistant to corrosion, chemicals, and root intrusion

• Suitable for a wide range of pipe materials including clay, cast iron, concrete, and PVC

• Fast installation reduces downtime and project costs

Ideal Applications:

• Municipal sewer systems

• Stormwater lines

• Industrial pipelines

• Residential or commercial drain systems

• Culverts and infrastructure rehabilitation

Thermoform pipe lining offers a modern, efficient, and long-lasting solution for extending the life of underground piping systems—without the mess and cost of traditional excavation.
