Geomembrane liners from DLM Plastics are used to control water loss and subgrade interaction in ponds, reservoirs, canals, and landscape water systems. Material formulations emphasize puncture resistance, dimensional stability, and long-term hydraulic integrity under fluctuating water levels and variable soil conditions. Available thicknesses and material types allow projects to be tailored precisely to slope geometry, loading expectations, and installation constraints. Flexible sheet formats streamline handling and seaming while maintaining consistent containment performance. For landscape architects coordinating grading, edge restraints, planting shelves, and overflow structures, these liners integrate cleanly into broader site systems. DLM Plastics’ liner solutions support durable, cost-effective water management across recreational, agricultural, and municipal landscape applications.
