System for Horizontal Drainage Beneath Paved or Green Areas
Geocell is a drainage cell structure made from regenerated polypropylene, designed to create horizontal drainage layers beneath paved areas or landscaped surfaces.
Its high void ratio improves stormwater runoff, preventing water stagnation and issues typical of poorly permeable subgrades.
Thanks to its functional geometry, Geocell prevents saturation of the bedding sand, which is the primary cause of degradation and uplift in interlocking pavements, particularly under vehicular traffic.
The system accelerates water evacuation and allows for a reduction in the thickness of the drainage package, delivering tangible benefits in efficiency, construction time, and overall project costs.
The 91% void ratio promotes rapid runoff and temporary storage of stormwater, reducing the risk of flooding.
Geocell limits water pressure beneath the pavement (pumping effect), preventing uplift and subgrade deformation.
The drainage structure speeds up water transfer toward collection systems and enhances infiltration, drastically reducing drainage times, erosion, and surface accumulation.
Prevents saturation of the bedding sand, maintaining a stable and safe surface even under heavy traffic conditions.
The cellular structure ensures robustness and durability, supporting high loads without permanent deformation.
The low-profile design and modular configuration improve transport and storage efficiency, reducing logistics costs.
Manufactured from 100% recycled plastic, Geocell helps reduce the CO₂ footprint by minimizing excavation requirements and is ideal for CAM, LEED, and BREEAM projects.
The system is EPD – Environmental Product Declaration certified and is designed to ensure a service life exceeding 50 years, making it suitable for public works and international projects.
WITHOUT GEOCELL
Gravel allows a monodirectional water movement, from upward to downwards. Once the soil saturates (especially when the permeability is very low) the movement is hampered and water remains on the surface.
WITH GEOCELL
GEOCELL, on the contrary, allows a bi-directional water movement both along the verticality and along the floor slope, channeling water to the drainage system. In this way, water can flow horizontally avoiding the system’s clogging, even in the case the underground becomes saturated and the infiltration inhibits.
