Installation
A vividly green, vigorously growing, well-kept lawn is a natural decoration, has a positive effect on our well-being, and also acts as a climate-creating factor.
When designing a living surface with geoSYSTEM, you should consider:
- what type of traffic will there be on the grate?
we advise against grassy surfaces with frequent traffic - will the surface be cared for?
checkered grass requires special care – frequent watering, mowing and fertilizing.
The surface of eco-grids should be laid on a water-permeable foundation.
Layer order:
– grid filled with soil with grass seeds, gr. 4 or 5 cm
– sand leveling layer th. 3 cm
– fertile layer of aggregate 0-31.5 mm with the addition of an intensive substrate (about 30%) th. 20 cm
– load-bearing layer, broken stone 30-60 mm, th. 10-40 cm
The thickness of the substructure depends on the purpose of the surface, usage and local conditions.
It guarantees stability of grid and load resistance. It also prevents surface deformation. On less permeable soils (e.g. clay), substructure should be approx. 20 cm thicker.
Recommended substructure thickness
Recommended use of substrate:
– to fill the grid – intensive lawn substrate ST – fraction 0-5 mm
– mix into the carrier layer – 30% intensive substrate SI – fraction 0-16 mm
Step-by-step assembly instruction
*If you fill the plates with stones, lay geotextile directly under the plates
**Installation of the geoSYSTEM F40 grids should start with the notches facing you
Notice
Parking spaces made of a grass grid should be used as temporary parking spaces, located far from the main entrance in the case of public facilities, so that the maximum parking time does not exceed 4 hours during the day, longer parking only at night. Thanks to this, the grass has a chance to grow, which means that the walls of the grate are completely overgrown, they do not stick out empty and are not exposed to breakage by the maneuvering wheels.
How to properly care for grass in an eco grid?
- Fill the grids with good, organic garden soil, with high humus content and pH of 5.5 to 6.5, or use standard substrate. The soil should not be too clayey, as it would form shell rapidly. It should not be to light (sandy) either, as it would quickly lose water.For improving drainage, aeration, and moisture retention, it’s worth incorporating perlite. The recommended ratio is about 10-20% by volume.
- After filling with soil, spray the grid with plenty of water to get proper compaction. The soil should reach approx. 0.5 cm below the edge of the cell wall
- Grass should be sown crosswise – with half of the seeds distributed along and half across the surface. Then, seeds must be covered with a several millimeter layer of sand (fraction 0.6 to 1.2 mm)
- During germination, it is particularly important to maintain proper soil moisture – water slightly in the morning. Grass sprouts will appear after approx. 3 weeks, if soil moisture is stable during that period
- Do not use the surface for the following 8 to 12 weeks, until grass roots become strong enough. Do not park cars on the grass surface for longer times
- First mowing is possible when grass is approx. 10 to 12 cm long. During the first year after sowing, keep the grass longer (4 to 5 cm) to let it spread over the surface quickly. When the lawn is dense enough, grass may be cut to 1 or 2 cm
We suggest choosing the geoGRASS mix, containing grass varieties particularly resistant to difficult soil and nutrition conditions, characterised by low nutrient requirements and resistance to drought
Use an appropriate type of grass. The sown seeds should be mixtures of several species and varieties of grass – this gives greater opportunities for plants to adapt to various conditions, both natural and functional.
The conditions in the lawn grids are particularly difficult. They should be filled with a suitable substrate. We recommend using an intensive ST lawn substrate with a grain size of 0-5 mm.
Important informations
- The geoSYSTEM G25 grid may be filled with recreational grass or used as lawn reinforcement against animals. In that case no substructure is required
- Cars should not be parked on the grass for more than 4 hours a day
- Eco grids are made of plastic that due to its properties stretches in high temperatures and shrinks in low temperatures – 5 cm gap should be maintained between the grid and other surfaces or objects fixed to the substructure, e.g. parking post (dimension stability +/- 3%). The gap must be filled with sand.
- Considering possible dimension instability, problems may occur while joining individual grids. To avoid it, we recommend using items from several pallets at a time. Large-size grids should be joined with medium-size grids. Medium-size grids should be joined with small grids.
- Cell walls must be completely filled with gravel or grass. Protruding grid structure could be damaged mechanically.
- While setting out surfaces with varied shape, trench banks may be reinforced with geoBORDER rims, installed with a 3 cm gap from other elements.
