Geocell for Strengthening the Substructure of Roads and Tracks
The GLOB-KRATA Geokrat Cellular System is a modern and cost-effective solution used in road and rail engineering. It is used to stabilize soils with low bearing capacity and to reinforce subgrades for asphalt and concrete pavements as well as rail tracks.
Thanks to its unique honeycomb structure, the geogrid traps aggregate inside the cells, forming what is known as a semi-rigid slab. This allows for the even distribution of dynamic loads, eliminates axial settlement, and reduces the thickness of the subbase layer by as much as 30–50%.
Why should you use GLOB-KRATA in the subbase?
Reduced subbase thickness: This allows for savings of up to 50% on crushed aggregate, reducing the costs of purchasing and transporting the material.
Prevention of rutting and settlement: Prevents lateral movement of aggregate caused by heavy vehicular and rail traffic.
Increasing load-bearing capacity on weak soil: Enables the construction of roads and open spaces on frost-heave, clay, and peat soils.
Durability and Resistance: The geosynthetic is 100% resistant to chemicals, fuels, freezing temperatures, and UV radiation.
Comparison of Subbase Structures: Traditional vs. Reinforced with GLOB-KRAT
| Feature / Parameter | Traditional Subbase | Subbase with GLOB-KRAT |
| Required aggregate size | Large (often 40–60 cm) | Reduction by 30–50% (e.g., to 20–25 cm) |
| Risk of Rutting | High with heavy traffic | Reduced to a minimum |
| Replacement of Poor Soil | Often necessary (costly) | Reduced or unnecessary |
| Material Transportation Costs | High (large volume of aggregate) | Significantly lower (less aggregate to haul) |
Frequently Asked Questions
How does geogrid help reduce costs in road construction?
The use of geogrids can drastically reduce the amount of aggregate needed. Less material means fewer truck trips, lower fuel costs, and a shorter project completion time.
What type of aggregate is best suited for filling geogrids in the subbase?
Crushed aggregate (e.g., unsorted 0–31.5 mm or 0–63 mm) provides the best results. For less demanding subbases, the use of recycled aggregate (e.g., concrete rubble) is acceptable.
Does a geogrid require the use of geotextile?
Yes, we always recommend laying a separating geotextile beneath the geogrid. It prevents aggregate from being pushed into soft native soil (clay, sand) and ensures proper drainage.

Do you need a stable base for roads and railways?
We are a Polish manufacturer of durable Geogrids – ideal for road and rail substructures.
Advantages of using GLOB-KRATA Geogrids in strengthening road substructures:
- Reduction of vertical stresses – the cellular geogrid acts as a semi-rigid plate, which significantly reduces the load on the ground, improving the stability of the surface.
- Increasing the load-bearing capacity of the subgrade – thanks to the use of geogrids and geocells, the geogrid effectively strengthens road subgrades, even in difficult ground conditions.
- Erosion resistance – the use of a geogrid protects the substructure against erosion, especially on surfaces with large slopes.
- Ideal for roads and rails – geogrid is perfect for reinforcing road surfaces for both road and rail vehicles, ensuring even load distribution.
- Simple installation and long-term durability – thanks to quick and easy installation and exceptional durability, the geogrid is an economical and effective solution for long-term use.
