Rents composite mat systems and provides site construction, logistics, and restoration services for infrastructure and energy work. Product sales extend the DURA-BASE mat platform to customers worldwide, while the company now reports one segment after exiting Fluids Systems.
Rents, sells, and services recyclable composite mat systems used to create temporary access roads, work pads, and grounded work zones. The DURA-BASE platform includes standard mats, the lighter 800 Series, and EPZ Grounding System, backed by planning, logistics, installation, and site restoration.
Revenue is concentrated in the United States and United Kingdom for rentals and services, with product sales reaching customers worldwide. End markets include power transmission, oil and gas, pipeline, renewable energy, petrochemical, construction, and other industrial work.
Execution depends on rental fleet scale, manufacturing capacity, service reliability, and the durability and reuse profile of composite mats. After the Fluids Systems sale, the company reports a single continuing segment shaped by worksite-access demand and alternatives from wood mats and competing composite systems.
