The loss of biologically active surface in dense urban areas forces the transfer of greenery to building roofs. Ecogrid systems play a key role in creating so-called green roofs, acting as a lightweight drainage and retention layer that does not overload ceilings while supporting plant vegetation.
- Reduction of ceiling loads: Plastic is a fraction of the weight of traditional drainage layers made of gravel or expanded clay, making it easier to design the building’s load-bearing structure.
- Water micro-retention: The grid cells store moisture essential for vegetation (especially on extensive green roofs), while also delaying stormwater runoff into the sewer system.
- Substrate stabilization: The grid prevents the vegetation layer (roof substrate) from slipping, which is crucial on roofs with a slight slope.
Implementation example: An office building certified under BREEAM with a roof garden accessible to employees. The use of grids to stabilize walkways with aggregate and in areas planted with sedum made it possible to meet strict roof loading standards.
Key investment benefits:
- Improved thermal insulation of the roof, which translates into lower building air-conditioning costs in summer.
- We care about retention: solutions support water infiltration into the ground.
- Protection of roof waterproofing against UV radiation and mechanical damage.
Recommended models for this application: In this application, low weight is a priority, not extreme load capacity. The optimal choice will be models: N30, N40, and in the case of higher loads (e.g., on viewing terraces with infrastructure), the N50 model.

Absolutely not. Any mechanical fasteners (e.g., anchors) risk puncturing the waterproofing membrane. The modules are joined only by integrated clips, laid freely as a floating layer.
Yes, however, the system is always installed on a properly selected protective and drainage layer (e.g., a special absorbent protective geotextile) that separates the rigid plastic from the delicate waterproofing membrane.
