A solid base is the foundation of any durable and safe ecological surface. Without it, even the best materials won’t do their job, and the investment will quickly require repairs.
Learn how to professionally prepare the ground for Ecogrid road grids so your surface is stable, fully permeable, and ready for the heaviest loads for many years.
Proper installation begins with excavation, i.e., removing the top layer of soil and accurately leveling the area. The depth of the excavation depends on the planned load – for passenger cars it is usually 30-40 cm. Next, a load-bearing layer is laid, most often made of road aggregate, which must be precisely compacted with a vibrating plate. At this stage, it is crucial to maintain proper slopes (approx. 1-2%) to help drain excess water during extremely heavy downpours. Another absolutely essential step is laying a separating geotextile. It prevents the coarse load-bearing layer from mixing with the top leveling layer (sand or fine gravel bedding). Such a properly prepared and compacted substrate ensures that geokraty have a perfectly even base, perfectly transmit vehicle loads, and the risk of unsightly ruts or subsidence of the surface drops to virtually zero.

Yes, its use is crucial. The geotextile separates the sub-base layers, preventing the aggregate from sinking into the ground while maintaining full water permeability.
Usually a layer of 3 to 5 cm is recommended. A too thick layer can cause instability of the grids.
For residential work, a plate compactor weighing 100-150 kg is sufficient. It is important to compact the load-bearing layers in stages (every dozen or so centimeters).
Why is it worth investing in a solid sub-base?
Although ground preparation takes the most time and materials, it is an investment that pays off in the form of absolute peace of mind for years. A well-made sub-base guarantees that Ecogrid will not crack, the surface will remain level, and rainwater will freely soak into the ground, preventing mud from forming.
n- Ensures many years of trouble-free life for a parking lot or driveway.
- Effectively eliminates the formation of ruts from car wheels.
- Maximizes the drainage properties of the entire system.
