Geomat - Three Dimensional Erosion Control Mat
Geomat
Geomat is a high strength mat material produced from polyamide or polypropylene raw material with an open, three dimensional structure. It prevents erosion on embankments, slopes, stream and river banks, canals and reservoirs. Geomat provides erosion protection by working together with vegetation. The open, three dimensional structure of the mat laid on the surface creates a volume that is more than ninety percent void; these voids hold seed and soil in place, preventing them from being washed or blown away. Over time, plant roots grow through the mat structure and form a continuous root network that interlocks the mat with the soil. As a result, protection becomes permanent once the vegetation cover has established, and the surface is stabilised both mechanically and biologically.
Geomat Functions
Thanks to its open, three dimensional structure, Geomat delivers erosion control by working together with vegetation. Laid on the surface, it holds seed and soil in place, and as plant roots grow through the mat structure, the mat and the ground interlock. In this way the surface is protected both during installation and over the long term.
Erosion Control
The mat laid on the surface prevents raindrops from striking the soil directly and reduces the velocity of surface runoff. This prevents soil particles from detaching and being carried away, preserving surface integrity even during periods of heavy rainfall.
Vegetation Support
The void structure of the mat holds seed and topsoil in place, providing the conditions required for germination. Plant roots grow between the mat filaments, and over time a continuous root network forms that interlocks the mat with the soil.
Surface Stabilisation
It limits the sliding and surface movement of soil on slope and embankment faces. During the critical period until vegetation establishes, it holds the surface mechanically stable, and afterwards it forms a permanent stabilisation layer together with the root network.
Drainage
Its open structure allows surface water to flow freely through the mat. Instead of pooling on the surface, water is discharged in a controlled manner, which reduces the risk of scouring and channel formation.
High Capacity Soil Retention
Geomat acts as a protective and integrated intermediate layer between the natural vegetation cover and the soil. By providing protection both above and below the water line, it creates a permanent solution. Seeded, topsoil filled or mulched Geomat holds fertile soil in place and prevents the embankment from being washed out.
Geomat Features
- With a void ratio of more than ninety percent, it provides water and air permeability, supporting root development and erosion control

- Plant roots grow through the mat structure, forming a continuous root network that interlocks the mat with the soil
- The strong bond at the filament junctions ensures the durability and dimensional stability of the mat
- It is lightweight and flexible, easily conforming to the geometry of the surface on which it is applied
- Thanks to its non absorbent polymer raw material, it does not rot or gain weight over time
- High UV resistance ensures long-lasting durability
- Requires no maintenance after installation
- Combines with the vegetation cover to create a permanent, natural looking solution
Frequently Asked Questions
1. What Is Geomat?
Geomat is a high strength erosion control mat produced from polyamide or polypropylene raw material, with an open, three dimensional structure. Thanks to its void ratio of more than ninety percent, it holds seed and soil in place while allowing plant roots to grow through the mat.
2. How Does Geomat Prevent Erosion?
The mat laid on the surface prevents raindrops from striking the soil directly and reduces the velocity of surface runoff. Its void structure holds seed and topsoil in place, and as plant roots develop, the mat and the ground interlock, making the protection permanent.
3. Is Geomat Used Together With Vegetation?
Yes, Geomat delivers its highest performance when working together with vegetation. The mat can be seeded, filled with topsoil or mulched; once the vegetation cover establishes, a permanent stabilisation layer forms together with the root network.
4. Where Is Geomat Used?
It is used for erosion control on highway and railway slopes, embankment surfaces, stream and river banks, canals, reservoir slopes and spillway areas. It provides protection both above and below the water line.
5. How Durable Is Geomat?
Thanks to its high UV resistance, it maintains its performance outdoors over a long period. As its polymer raw material does not absorb water, it neither rots nor gains weight over time, and it requires no maintenance after installation.
6. Does Geomat Allow Water to Pass Through?
Its open structure gives it high water and air permeability. Surface water flows freely through the mat and is discharged in a controlled manner, reducing the risk of pooling and scouring on the surface.
