APM

Waterline Renewal Technologies (WRT) supplies and manufactures products and systems for trenchless rehabilitation of sewer networks and potable water pipelines. Its technologies are designed to address degraded infrastructure, help prevent water inflow and infiltration, and restore pipes from within while reducing the need for excavation. WRT serves residential, commercial, and municipal markets, supporting projects ranging from small-diameter drains to mainlines, lateral connections, manholes, and lift stations.

The company brings together four specialist brands: APM, focused on sewer-line repair and manhole and concrete-pipe restoration; LMK Technologies, known for CIPP lateral renewal and connection-lining systems; LightRay, which offers ultraviolet-cured CIPP lining and spot-repair solutions; and Perma-Liner, a manufacturer and supplier of trenchless rehabilitation equipment and materials. Products include liners, resins, repair systems, coatings, mortars, waterproofing products, and installation equipment. WRT also offers turn-key trailers and box trucks, distributes selected equipment, and provides training, certification, technical support, and access to certified installers. Its solutions are used by contractors, property owners, and infrastructure operators seeking to rehabilitate underground pipelines.
