The strong and lightweight rehabilitation solution
The SPR™ EX lining system is a unique process for restoring the hydraulic efficiency, reliability and integrity of aging sewers, storm drains and culverts.
The system consists of a single, manageable strip of PVC profile, which is progressively wound into the existing pipeline via a patented winding machine positioned in the base of an existing manhole or access chamber.
The edges of the profile are interlocked as the PVC profile is spirally wound to form a continuous watertight liner inside the host pipe. Once the PVC profile is installed, a patented process is used to radially expand it to fit tightly against the wall of the host pipe.
SPR™ EX – Easy installation with long-term benefits
SPR EX liners can structurally rehabilitate brick, concrete, glass, reinforced plastic or corrugated metal sewer and storm water pipelines with diameters from 6” to 30”.
The installation can be performed even while the pipe is in use. Additional costs such as bypass are eliminated. This optimized method can install new linings into a large number of old pipes within a single day.
SPR EX™ product and process quality is ISO 9001 certified.
