The SG4 gravel grid, also known as the paddock grid, is designed for the most demanding conditions. The main applications of the SG4 gravel grid include parking lots, heavy traffic roads and horse paddocks, where the pressure is distributed more point-wise. Behind the above-average strength of the SG4 gravel grid is a slightly more closed structure and thick walls , which prevents the movement of gravel (in the case of parking lots and heavy transport roads) and sand in the case of horse paddocks. In addition, the SG4 model allows natural drainage of rainwater, creating a SUDS compliant surface.
The SG4 model, thanks to its exceptional durability, exceeding standard gravel grids, makes it an excellent replacement for paving stones, for example. SG4 gravel grids in accordance with DIN EN 1072:1985 can withstand a permissible pressure of up to 500 t/m², which makes them extremely durable and reliable even under the harshest conditions. Installation of these gravel grids is simple thanks to intuitive “click” connections.
The gravel grids are available in the following dimensions: 50×50×4 cm, 50×50×5 cm, 60×40×4 cm.
Available colors:

The gravel grids can be filled with soil with sown grass or all kinds of gravel up to 20 mm in size. The design of the gravel grid prevents the migration of aggregate and the formation of ruts or puddles. The gravel grid layer filled with gravel creates an even and comfortable surface for car and pedestrian traffic.
The material for the production of the gravel grid is regranulate (polyethylene), which was obtained in the process of recycling selected post-industrial waste. This makes the material not only durable, but clean and free of heavy metals. Durable and safe for the environment.
Installation is quick and easy. The individual panels are connected by integrated hooks at the edges of the individual gravel grids, leaving an expansion joint. The structure is strong and at the same time fully openwork. The roots of the grass can grow perfectly in the grid, creating a stable
SUDS compliant surface in every direction.
The SG4 gravel grid is a great substitute for paving stones, asphalt or openwork concrete slabs, especially where it is important to maintain a biologically active surface. The SG4 gravel grid, due to its reinforced structure, is perfect for use in parking lots, paddocks and heavy transport roads. This model has been designed for the toughest conditions on demanding terrains. It is ideal both as a product for public investments, parking areas, and as a durable alternative to stabilize horse paddocks.
Stella Green gravel grids, including the SG4 model, have passed tests carried out by the German organization TÜV SÜD, confirming compliance with the DIN EN 1072:1985 standard, which is crucial in the design and construction of fire roads. SUDS compliant.
The Stella Green gravel grid (Model SG4) is used, m.in, for:

The installation of the gravel grid should not take place at a temperature below 2 degrees Celsius.
The installation of the gravel grid itself is quick and uncomplicated. Thanks to the integrated hooks on the edges of the gravel grids, the individual elements are very easy to connect to each other.
The most important factor influencing the longevity of a gravel grid structure is a properly made substructure. We have also prepared special instructions on how to make one to enjoy a properly laid grate for many years. Gravel grid installation step by step
In order to properly prepare the substructure for the laying of gravel grids, it is necessary:

Gravel grids are special openwork panels made of durable materials such as polyethylene. They are used to stabilize the soil, allowing the load to be evenly distributed on the surface, which prevents rutting and damage. Thanks to the grid structure, rainwater can seep freely, which contributes to maintaining the biologically active surface. This product is available in brown, thanks to which it looks very natural and fits into any surface. If you are interested in the green or black color of a rectangular geogrid, read about the SG6 Geogrid.
These gravel grids are characterized by high durability, resistance to weather conditions and ease of installation. They are made from recycled materials, making them an eco-friendly choice. In addition, thanks to the possibility of filling the gravel grid with grass or gravel, it is possible to create aesthetic and functional surfaces that are environmentally friendly, allow for greater loads. In addition, compared to paving stones, the lawn trellis has a much better price-quality ratio, and its installation is really simple.
No, laying the substructure is necessary. In the place of pedestrian traffic, the substructure should be 20 cm, and in the place of road traffic – 40 cm. The substructure consists of a substructure, a levelling course and two layers of geotextile separating the substructure from the other layers.
Yes, depending on the model and pallet height, there are from 176 to 336 pieces of gravel grids per pallet. The Stella Green gravel grid is available in small quantities as well as in pallet quantities.
Square grass grids by Stella Green – SG1 and SG3 need exactly 4.56 pcs. per 1m2 . Rectangular gravel grids, on the other hand, SG4 and SG6 you need exactly 4.57 pcs. per m2 .
The Stella Green gravel grid (or parking parking) is ideal for the garden and horse paddocks and applications in parking lots, driveways, fire roads and green areas and other surfaces. Thanks to their design, they are suitable for soil reinforcement in places exposed to heavy loads, such as car parks. These gravel grids can also be used to create garden paths and reinforce slopes.
Yes, Stella Green gravel grids are tested for load resistance and meet the requirements of DIN EN 1072:1985. This means that they are strong enough to support the weight of vehicles, including cars, motorhomes or vans. Tests carried out by the German TÜV SÜD confirm their durability and reliability up to 500 tons/m2. In addition, the grating is resistant to acids, compression and damage.
Installation of Stella Green gravel grids is simple and quick. The substrate should be prepared, i.e. remove the soil layer, to a level that will allow all layers of the substructure to fit (it is worth keeping a 1-2% slope in the best direction for water runoff). Then the area should be covered with geotextile (100-300 g/m2). The next step is to cover the area with the load-bearing layer (details on the composition of the load-bearing layer can be found in the link below). Then, the geotextile should be laid again, and the levelling layer should be poured on it and the mixture should be compacted with a compactor. In the final step, the gravel grids are laid on a prepared surface and filled with material such as aggregate, gravel or sown with grass (see link below for details). The gravel grids can be easily cut to fit any shape and size of surface. Click on the link, select the language and learn how to install the gravel grid step by step: https://installation.info.pl/.
Gravel grids for soil reinforcement are available in DIY stores and on Allegro or Erli under the slogan “Stella Green parking grid”.
Wholesale quantities (1 pallet and up) can be purchased from our distributors or by contacting our advisors.
The nomenclature is used interchangeably due to its wide range of applications. In the case of Stella Green gravel grids, there are 4 models of this product: SG1, SG3, SG4 and SG6, all of which are used in parking lots, driveways, bicycle paths, allotments and in the garden. The models differ from each other in dimensions, colors and typical use (for example, the SG4 model is an alternative to concrete slabs – it is a grid that is characterized by very high durability, which is why it is also used on roads for heavy transport and horse paddocks, where the pressure is distributed more pointically). The product is available immediately.
