Liber Grids

LiBER GRIDS manufactures stormwater inlet grids designed for civil engineering infrastructure. The product is the result of 23 years of research and development in civil engineering projects and stormwater systems implementation.

The company offers patented stormwater grids in multiple configurations for load classes ranging from pedestrian-only (Class A 15kN) to heavy vehicle traffic (Class C, 250kN). Products are manufactured from galvanized mild steel S355JR with permeability ratios ranging from 59.4% to 96.8%. All grids feature a patented lock and key system for theft prevention and easy maintenance access.

LiBER GRIDS provides a 25-year guarantee on its products. Systems are engineered to cope with high volume thunderstorms and long periods of rain, supporting heavy traffic while ensuring surface water drains quickly and efficiently. The company supplies municipalities, civil engineers, infrastructure developers and public-sector project teams.

Products are designed for residential estates and internal road networks, retail centres and mixed-use precincts, commercial office parks, schools, hospitals and public buildings, parking bays, drop-off areas and service routes, and industrial and logistics sites. LiBER GRIDS operate as linear drainage systems placed along paved surfaces, entrances, thresholds, roadways and high-flow runoff points. Full CAD files, technical drawings and installation guides are available to assist architects, engineers and construction teams.
