Geosynthetic materials have long proved their effectiveness and become indispensable in the construction of a variety of sites: from road junctions to agricultural complexes.
Depending on the initial data, purpose and design decision, a different type of geocell can be used to implement the project. This time we will share the secrets of applying three-dimensional geocells in road construction.
Here are the most common problems encountered during the operation of roads:
Cracks (longitudinal, transverse, mesh cracks)
Suffusion and erosion processes
We have collected the most frequently asked questions:
1. How to choose a suitable geocell?
To strengthen the roadway, we recommend the reinforced geocell GEOCORD®, a geocell material of a new generation. Its key feature is the reinforcement by polyethylene tapes with high-strength synthetic threads. The threads increase the strength of the structure and contribute to the preservation of stable geometric characteristics for a maximum period. The principle of operation of GEOCORD® is to redistribute the vertical load on adjacent cells (the FLEXIBLE PLATE effect), which allows reducing the voltage on the underlying base. You should also pay attention to the height of the geocell: it depends on the current loads and traffic flow.
2. What tools will be needed?
To install the geocells, you will need accessories for fastening the sections. The traditional way is using a stapler and staples, but you can use a more modern alternative, the FAST-LOCK® fastening key.
In addition, the structure must be fixed to the surface: anchors (plastic PRUTTEX®, composite GEOFORCE®, or metal fittings) or a polyamide cord will help with this.
3. What needs to be done before starting work?
Before starting work, make sure that all excavation work has been completed, and also check the foundation parameters (degree of compaction, length, width, longitudinal and transverse slopes) for compliance with the design.
4. Which aggregate material to choose?
This is really a very important issue since the wrong choice of aggregate material can cause the deformation of the structure and significantly reduce the life of the object.
Depending on the application, the following materials are used: mixtures, plant-soil / mineral material - for strengthening (reinforcing) special landscaped sections of parks for walking along them and parking cars and sand, gravel, gravel - for any road surfaces.
It is necessary to pay attention to the composition and size of the filler fraction, this can contribute to a more correct distribution of the upper load.
In addition, it is often advantageous to use local materials as a filler: this will help save on logistics, and it is more environmentally friendly.
