A durable and fully permeable layout using OCITY PAV65 and NGR65 grids
Nidaplast supported the development of a fully permeable parking area with nearly 70 spaces for a Carrefour retail site in Touques, near Deauville.
The design combines PAV65 cellular paver grids and NGR65 grass grids to create a mixed paver/grass parking solution that is aesthetic, high-performance and fully compliant with regulatory requirements.

Project Context and Challenges
Building a durable, de-sealed parking area compliant with the ALUR regulation
During the car park renovation, the project owner aimed to:
- de-seal the surface,
- facilitate natural infiltration of rainwater,
- reduce load on the stormwater network,
- provide a driveable and aesthetic solution suitable for commercial traffic.
Engineering offices also integrated the need for PRM and family spaces and a surface suitable for light vehicle traffic.
Objectives Defined by the Project Owner
The specifications required:
- a 100% permeable parking solution,
- a combined paver/grass system ensuring both strength and landscape integration,
- solutions compliant with ALUR requirements,
- a stable, durable structure resistant to compaction and climatic cycles,
- fast installation to limit disruption for customers.
Solution Implemented with Nidaplast
OCITY PAV65 and NGR65 cellular grids
The design relies on two complementary OCITY grids:
PAV65 – grid for driveable pavers
- Pocket for 9 concrete pavers (6 cm thick)
- High mechanical resistance
- Ensures perfect alignment and stability
- Suitable for regular light-vehicle traffic
NGR65 – grid for natural grass (or gravel)
- Deep cells promoting vertical and lateral root growth
- Excellent air, water and nutrient circulation
- Allows direct infiltration of rainwater
- Can also be filled with gravel if required
The two grids are fully compatible thanks to a clipping system ensuring continuity between paved and grassed areas.
Technical Characteristics of the Installed Product
Panel size:
500 x 500 mm.
Grid height:
65 mm.
Permeability:
Aligned with sustainable urban drainage guidelines (SuDS)
Material:
100% recycled and recyclable polyethylene
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.
View product sheetInstallation Process
1. Preparation
Earthworks, sub-base levelling and installation of a draining bedding layer.
2. Laying OCITY grids
Installation of PAV65 and NGR65 grids, clipping paved/grass areas together for structural continuity.
3. Filling and finishing
Filling PAV65 with 9 driveable pavers per grid.
Installing substrate and sowing/laying grass in NGR65 zones.
Adequate irrigation is required for proper rooting.
Grass becomes driveable after full rooting (a few weeks).
Results and Benefits Observed
- 100% permeable parking, direct infiltration of rainwater
- Reduced runoff and decreased load on networks
- Aesthetic paver/grass mix, fully integrated into the site
- Compliance with local stormwater management requirements
- Durable, stable solution requiring simple maintenance
- Optimised accessibility: 11 PRM & family spaces
