SPR™EX Spiral Wound Liner

150 mm – 1050 mm Pipe Lining

Close-Fit Lining

100% Trenchless

Close-Fit Liner for Small Diameters

The SPR™EX method is a statically self‐supporting spiral wound pipe system for the rehabilitation of pipes with nominal diameters of DN150 to DN1050. The SPR™EX technology has been specially developed for the rehabilitation of pipelines in earthquake zones and landfills. SPR™EX therefore has extreme properties in terms of load‐bearing capacity and tightness.

SPR™EX Trenchless Lining Process

SPR™EX Lining Process

This technology is a close‐fit process in which the winded liner fits tightly to the pipe after rehabilitation. SPR™EX is 100% trenchless (standard manholes).
