Installation tips

1. The soil is excavated. Depth depending on the requested load capacity. For passenger cars: 20-30 cm deep. For soils with poor water permeability, we recommend to excavate 40 cm.

5. Next, lay out the ground plates in rows.

6. Compact the soil by vibration

2. Create a boundary on the edges (or check any existing boundaries).

7. Ground plates can be filled with a mixture of compost and lava rock or humus. Sow with grass seed and cover with a thin layer of sand (to prevent it from blowing away). Use grass seed suitable for dry soil.

3. Fill it equally with broken debris (10 to 20 cm). Then apply a layer of approximately 4 cm of sand with compost mixed soil and level it out.

8. Spray the surface in such a way that the filling reaches approx. 1 cm below the rim of the grass tile. Finally, keep the surface moist until the grass begins to grow.

4. Level out the surface and compact the soil by vibration.

Use grass seed suitable for dry soil. Ground plate filling: use humus with compost or sand. The fill layer to equalize the soil can be filled with sand to approx. 4 cm. Broken debris 15 to 55 cm (depending on the load).

Example of layer thicknesses
– driveways 20-25 cm
– parking spaces 25-30 cm
– heavy trucks 45-55 cm

Advice for pavements using plastic grass tiles

A.1 Foundation

A. 1.1 Foundation for heavy loads (road verges) – user class A

  • Excavated and leveled area with 1 to 3% inclination.
  • Geotextile according to the provisions of PTV 829 – table 2: geotextile used in road construction, application ‘roads (layering)’.
  • Layer of compacted stone chippings 10/32 with a thickness of 0.30 m to 0.50 m (possibly with 10% to 20% of soil).
  • The layer thickness should be in relation to the load capacity of the surface.

  • Geotextile according to the provisions of PTV 829 – table 5: Geotextile for use in drainage systems, with a thickness of at least 1.5 mm (at 2kPa).
  • Paving layer from 3 to 5 cm porphyry stone chippings 2/7 (possibly with 30% sand).
  • Plastic grass tiles with filling according to A.3.

Note 1:
The hardening should always be permeable, meaning that limestone, dolomite or broken debris cannot be used. The use of a discontinuous grain prevents water puddles.

Note 2:
The foundation must comply with a load capacity of 110 MPa (plate test).

A.1.2 Foundation for regular loads (parking) – user class B

  • Excavated and leveled area with 1 to 3% inclination.
  • Geotextile according to the provisions of PTV 829 – table 2: geotextile used in road construction, application ‘roads (layering)’.
  • Layer of compacted stone chippings 10/32 with a thickness of 0.20 m to 0.30 m (possibly with 10% to 20% of soil). The layer thickness should be in relation to the load capacity of the surface.
  • Geotextile according to the provisions of PTV 829 – table 5: Geotextile for use in drainage systems, with a thickness of at least 1.5 mm (at 2kPa).
  • Paving layer from 3 to 5 cm porphyry stone chippings 2/7 (possibly with 30% sand).
  • Plastic grass tiles with filling according to A.3.

Note 1:
The hardening should always be permeable, meaning that limestone, dolomite or broken debris cannot be used. The use of a discontinuous grain prevents water puddles.

Note 2:
The foundation must comply with a load capacity of 110 MPa (plate test).

A.1.3 Foundation for light loads (pedestrians) – user class C

  • Excavated and leveled area with 1 to 3% inclination.
  • Geotextile according to the provisions of PTV 829 – table 5: Geotextile for use in drainage systems, with a thickness of at least 1.5 mm (at 2kPa).
  • Paving layer from 3 to 5 cm porphyry stone chippings 2/7 (possibly with 30% sand).
  • Plastic grass tiles with filling according to A.3.

A.2 Anchoring

The use of anchoring pins prevents any friction between the tiles and the foundation and is necessary when:
– the product is applied on inclined surfaces (embankments, steep driveways, etc.);
– the product is applied with loose connections for user class B.

A.3 Filling

A.3.1 Grass filling

  • Filling of the chambers is done with a rich mixture.
  • An homogeneous mixture of broken and expanded clay grains, fine green compost, washed river sand and fertilizer is an example of a rich mixture.

Composition of this homogeneous mixture:

  • broken and expanded clay grains 4/8: 30 vol. %;
  • fine green compost: 40 vol. %;
  • washed river sand: 30 vol. %;
  • fertilizer: 1 kg/m³ mixture.
  • Fill the plastic grass tiles and remove the excess material (dragging).
  • Prevent the mixture from compacting at all times. Spray with water (or allow for rain water) until the filling material drops to 0.5 to 1 cm below the top of the plastic grass tiles.

  • Sow the plastic grass tiles with a suitable grass mixture that will withstand thaw salt, 50 g/m². An example of a suitable grass seed mixture: 4 selected varieties of rye grass and fescue grass (60% Festuca Commutata (2 varieties) – 30% rye grass – 10% Festuca Rubra Rubra.

Note 1:
After finishing, the plastic grass tiles should be walked or driven on as little as possible until a sturdy grass turf is obtained.

Note 2:
The filling should be permeable at all times. The use of a discontinuous grain prevents water puddles.

A.3.2 Stone chippings filling

  • Fill with fine stone chippings (e.g. porphyry 2/5 or porphyry 2/7).
  • Remove any excess material.

Note:
The filling should always be permeable, meaning that limestone, dolomite or broken debris cannot be used. The use of a discontinuous grain prevents water puddles.
