Stable ground, effective drainage and load resistance — these are the three key criteria that well installed lawn grids. Whether used on driveways or car parks, as well as in domestic gardens, they are an attractive alternative to classic concrete paving. Their correct installation is not only a question of aesthetics, but above all of durability and proper functioning of the surface.
How to lay lawn gridsHow do you ensure that they fulfil their role for many years? This is a multi-stage endeavour — from the preparation of the substrate, to the installation itself, to the correct filling. In this guide, we discuss the entire procedure step by step.
The first stage before the actual laying lawn grids is to remove the turf and any debris such as stones or root debris. The trench should then be excavated to a depth appropriate to the anticipated load — approximately 10 cm is sufficient for pedestrian traffic, while a minimum of 30 cm will be necessary for areas used by vehicles.
The next stage is to stabilise the subsoil. For this, a base layer of crushed aggregate such as basalt or granite grit is used. The aggregate fraction should be between 5 and 32 mm, depending on the intended use of the surface. To prevent mixing of the layers, the use of a separation geotextile is recommended.
The final step is to level and compact the substrate. For this purpose, it is advisable to use a plate compactor, which will allow you to achieve the right bearing capacity and avoid unevenness during the installation of the gratings. The base thus prepared provides a solid support for the pavement.
Once the substrate has been properly prepared, the actual installation can begin. How do I lay lawn grids? The most important thing is to maintain an even distribution of the modules and to ensure their full stability. This process consists of several steps:
Precision during laying lawn grids influences the final stability of the ground, which is important especially for surfaces used by vehicles.
Upon completion laying lawn grids should be filled with a suitable material, adapted to the intended use of the surface. In the case of green areas, fertile soil is best for rapid grass growth. It is a good idea to roll the seeds gently to increase their contact with the soil and speed up rooting. For car parks and driveways, use aggregate with a grain size that matches the design of the grids to ensure better pressure distribution and reduce the risk of settlement. Once filled, the surface should be levelled and, in the case of lawn, watered regularly to accelerate establishment.
Correct laid lawn grids is an investment in pavement stability and efficient water drainage. The correct preparation of the substrate, the precise joining of the modules and the right choice of infill guarantee a long service life and load resistance — even for many years to come. By adhering to the principles described above, you will create a durable cut-out that will stand up to the demands of pedestrian and vehicle traffic.
