What Is Geomat? Uses and Benefits

What Is Geomat?

What is geomat? Geomat was traditionally used in agriculture, but today geomat is more commonly used for commercial, residential and industrial purposes.

The material has a three-dimensional design and is made from water-permeable synthetic materials such as polymers and polypropylene. These two synthetics are fused together using heat technology, which improves the weather resistance and lifespan of the geomat.

Geomat (Erosion Control Mat) / HDPE geomat is a type of geosynthetic with a three-dimensional structure, thermally bonded together, made from synthetic filaments arranged into a layer.

Geomat for Slope Protection

Getting grass to grow well on a slope is not always easy, because the soil is not always fertile. Low or very heavy rainfall can also slow growth. A bare slope has a higher risk of erosion, and if that happens, many people can be affected.

The erosion control material in a geomat is made from reinforced polyester for integration with geogrid. Other materials may include high-density polyethylene, which allows stronger and deeper root development.

Geomat Product

Geomat is typically used to establish vegetation on hillsides, roadside slopes and similar areas to prevent surface erosion.

Geomat Applications:

• Hillside slope reinforcement (protection against erosion and landslides).
• Roadside slope reinforcement.
• Riverbank protection.
• Landscaping.
• Dams.
• Railways.

Geomat Advantages:

• Reduces construction costs and is cheaper than concrete slopes.
• Resistant to chemicals and does not pollute the environment.
• UV resistant.
• Flexible and lightweight.
• High chemical stability and does not contaminate the environment.

Installation

When installing geomat, the first step is to dig an anchor trench. Its purpose is to fix the geomat to the ground surface. The anchor trench should be 300 mm wide and 300 mm deep. On slopes, the anchor is made by digging a trench beyond the crest of the slope, at least 600 mm from it.

Once laid in the trench, immediately fix it to the trench bottom using ‘U’-shaped pins or staples. Pins should be at least 8 mm in diameter and 150-300 mm long, adjusted to the consistency of the sub-grade soil the geomat is placed on. Pins should be spaced no more than 1 metre apart along the trench. To keep the material from being damaged, the trench is backfilled and then properly compacted.
