Permeable car park construction
Create durable and aesthetic permeable car parks with natural infiltration
Designing a high-performance permeable car park requires products matched to traffic load, infill type and regulatory requirements.
Nidagravel NG040, Nidagrass and Ocity grids enable the construction of permeable car parks combining mechanical strength, natural drainage and landscape integration.
Their honeycomb structure stabilises gravel, turf or pavers supporting light to heavy vehicles while promoting the natural infiltration of rainwater directly into the ground.
Available in several formats and thicknesses (40 mm to 65 mm), these solutions suit all project types: residential car parks, public parking areas, driveway access, fire lanes and service areas.
They contribute to soil de-sealing and comply with current sustainable stormwater management requirements.
Choosing the right grid for your permeable car park
Slab NG040
The nidagrass NG040 grass slabs are low-density recycled polyethylene (LDPE) panels designed to be grass-filled. They were specifically developed to provide a stable and driveable grass surface, preventing the formation of ruts, depressions, or puddles.
Slab RG035
The Nidaplast RG035 slab is an ideal choice for reinforcing existing grassed surfaces. This polyethylene panel has been specifically designed for renovating trafficable areas covered with grass. It provides a practical and effective solution to improve surface stability and reduce sinking.
Slab PAV65
The Ocity PAV65 slab is specifically designed for installing 15 × 15 × 6 cm pavers. Its structure ensures perfect alignment and excellent mechanical strength. Ideal for car parks, driveways, and trafficable areas, it facilitates the creation of durable and permeable surfaces.
Slab NGR65
The Ocity slab stabilizes both gravel and grassed surfaces while preserving soil permeability. Its honeycomb structure provides excellent mechanical strength and ensures a stable, driveable surface as well as deep grass rooting. Ideal for urban landscaping, it combines functionality, drainage, and long-lasting aesthetics.

Frequently asked questions
Are permeable car parks built with these grids truly permeable?
Yes. Nidagravel, Nidagrass and Ocity grids provide full permeability thanks to their open structure.
Rainwater naturally infiltrates into the ground, reducing runoff and helping to recharge groundwater.
These systems fully align with the principles of surface de-sealing and sustainable site design.
Can the grids be installed on a slope?
Yes, the grids can be installed on slopes of up to 10%, provided that installation guidelines are followed (sub-base preparation, proper compaction and appropriate filling).
This stability allows the construction of gently sloped driveable areas or permeable parking surfaces, while maintaining the integrity of gravel, grass or pavers.
Can you assist with the layout planning of a permeable car park?
Yes. Nidaplast’s technical teams support engineering offices and contractors with layout and installation planning.
We deliver optimised installation drawings adapted to site constraints (shapes, slopes, access, driveable zones) to streamline implementation and minimise cutting on site.
How can parking spaces be marked on a permeable car park?
Parking spaces can be marked using Nidaplast Marker inserts, available for each grid type (Nidagravel, Nidagrass and Ocity).
These discreet and durable markers fit directly into the cells and provide a clear, long-lasting delineation.
