Company Overview

Underground Solutions is an infrastructure technology and pipeline rehabilitation company. UGSI has developed and continues to develop unique and proprietary technologies focused on the underground infrastructure industry. UGSI's Fusible C-900®, Fusible C-905® and FPVC® products contain a proprietary PVC formulation that, when combined with UGSI's patented fusion process, results in a monolithic, fully restrained, gasket-free, leak-free piping system. Fusible C-900®, Fusible C-905® and FPVC® are NSF-61 certified, comply with AWWA C900 and C905 standards and cover a full range of piping diameters from 4 inch to 36 inch (with larger sizes in development) and provide the only available method of installing a continuous, monolithic, gasket-free PVC pipe or conduit capable of being used in numerous trenchless or conventional "open-cut" applications including:

Fusible PVC<sup>®</sup> can be swept through curves without the need of mechanical fittings

Applications for this technology cover every aspect of piping installations including both pressure and non-pressure situations in the water, sewer, electrical, industrial and telecommunications industries. Fusible C-900®, Fusible C-905® and FPVC® pipe have been installed at over 2000 sites throughout the US, Canada, New Zealand and Mexico.

The Underground Solutions Fusion Process: Fusible C-900®, Fusible C-905® and FPVC® have distinctive properties allowing full strength butt fusion joints. While other thermoplastic materials have been fused routinely, the Underground Solutions PVC field fusion process incorporates a patented combination of heat, pressure and time while using industry standard fusion machines to create the unique high strength joint.
