Alternatives to paved surfaces arecurrently being discussed on many levels. Some local authorities already require alternatives to paving while other local authorities charge fees for sealed surfaces. The ACO Self® grass grid offers the possibility of creating an occasionally trafficable, reinforced, lawn. The optimal cell size results in a high proportion of grass with good root growth, which helps to loosen the soil. This means that the percolation capacity is maintained over the long term. Easy installation is facilitated by the low weight of the ACO Self®grass panels for permanent stability of the surface, local soil conditions must be taken into account before installation.
- ACO Self® grass grid with substrate filling
- Levelling layer approx. 3 to 5 cm
- Water-permeable base layer 15 to 45 cm, depending on the load and local soil conditions
The track to be driven on is marked out. The soil is excavated to a depth of approx. 20-30 cm, depending on the subsequent load on the area, e.g. for cars. For soils that are difficult to permeate, e.g. clay, an excavation of approx. 40 cm is recommended.
Installation of the edging: A stable edging, e.g. of grass curbs (set in concrete), should always be present around an area.
After the boundary has set, the excavated base is mechanically compacted, e.g. with a compactor.
Place and compact the base course, e.g. consisting of gravel/crushed stone 2/32-2/45. The layer thickness should be approx. 15-45 cm, depending on the subsequent load and local soil conditions.
The material should not contain any fines, otherwise the infiltration of rainwater is not guaranteed.
An approx. 4 cm thick levelling layer of sand or a mixture of sieved compost with sand/lava (ratio 50/50) is applied to the sub-base and smoothed out.
The levelling layer should have humus content so that the lawn roots can take root in it and the stability of the entire surface is achieved.
Then connect the ACO Self® turf honeycombs first in the longitudinal direction. Then fasten them in the transverse direction. To do this, lift the grids slightly at the bottom of the slab and push the tabs into the recess with the point elevation. ACO Self® grass grid can be cut/sawed to any size using commercially available equipment.
The ACO grass grids are filled with a mixture of topsoil and sand/lava (ratio 70/30), for example, and sown with lawn seed.
Water in the substrate so that it is approx. 0.5 cm below the top edge (to protect the turf). After completion and sowing of the lawn seeds, water the area regularly. The lawn should have been cut approx. 3-4 times by the time it is driven over for the first time in order to achieve a continuous green surface.
Care and maintenance: fertilise regularly, water if necessary and mow.
It is advantageous to lay the flooring in a bond rather than on a cross joint and, if possible, at right angles to the direction of travel.
