About the company

Dimex creates and supplies durable products made from recycled plastics for outdoor and industrial use, including EdgePro landscape edging, paver restraints, industrial matting, and marine dock edging. Its manufacturing process includes a vertical integration approach and its own compounding division, which makes recycled PVC and TPE compounds, enabling both internal production and external supply of sustainable materials. The company distinguishes itself through owning material creation (compounding) and a diversified product line built around recycled plastics, plus established distribution with major U.S. retailers, supported by strategic acquisitions over time. Dimex’s goal is to provide sustainable, recycled-material solutions for outdoor construction and industrial needs while scaling its business through expanded product development and partnerships, culminating in integration into Westlake Corporation’s building products portfolio.
