The NIDAPLAST EP range includes honeycomb modules for stormwater retention and infiltration. These lightweight, highly resistant structures are used to build underground storage basins – also known as stormwater tanks – that collect runoff from roads, car parks or industrial areas. Made of Ultra-Light Cellular Structures (SAUL), NIDAPLAST EP modules offer up to 95 % void ratio, ensuring maximum storage capacity with minimal footprint. Installed underground and covered with soil or asphalt, they can withstand heavy traffic while preserving surface land use.
