3D Drainage Geomat

3D Drainage Geomat is a three dimensional synthetic erosion control mat. It prevents the erosion caused by rain, wind, hydraulic action or revegetation of soil slopes.

It can replace the slope materials such as concrete, bitumen and stone. Its 90% voids can be filled with soil or plant roots, combining soil and geomat firmly together to protect the slope.

Erosion Control

The three dimensional entangled mesh of the 3D geomat is made up of heat-tangled and fused polyethylene filaments. The strands are loosely spaced, which allows plants to grow through the geomat, and they also imitate the role of plant roots to bind soil particles together. This prevents the loosened soil from being washed away by rain or running water.

This drainage mat is also a good choice for protecting slopes, especially those that will be exposed to sunlight and wind. It can be used as an alternative to more expensive materials, such as block stone or concrete. Its high tensile and shear strength make it able to withstand strong pressure. This helps prevent the erosion of topsoil or vegetation during construction and long-term use.

In addition to its excellent drainage capacity, this geomat has the function of promoting seed germination and helping to maintain soil stability. Its black PE material also has the effect of absorbing sunlight and preserving warmth, which is helpful for grass growth.

3D Drainage Geomat is often used in landscaping, linear protection and in construction projects. It can help reduce the cost of materials by replacing more expensive material like concrete, asphalt and block stone. It is especially popular in highway, railway, airport and river slope protection projects because it can withstand heavy loads without tearing or breaking.

Slope Stabilization

Slope stabilization is the most important purpose of 3D Drainage Geomat, it’s a three dimension erosion controlling carpet which strengthens the soil slope’s endurability and prevents landslide and etiolation. It is also a cost effective substitute for concrete, asphalt and block stone in repairing the tilted terrains.

Compared with other conventional materials, Geomat’s drainage capacity is much higher. It can withstand long term high pressure and has shear and tensile strength. It 3D Drainage Geomat is mainly used for the slope protection of roads, railways, rivers and dams to replace the old concrete, asphalt and block stone.

Geomat’s wavy fibers are entangled together through heat fusion and have over 90% void space, which means that it can hold a lot of plant roots. This allows plants to grow naturally in the slopes, protecting the soil and preventing water from flowing out of the slopes.

There are five types of main membranes to choose from: coconut, HATE, FORTRAC, Fortrac 3D and Megamat. They differ from each other in color, shape and size of reticle. The more resistant the membrane, the more expensive it is. The best choice is to select the one which has a lower visual impact and can camouflage with the soil or vegetation. Besides, choosing a biodegradable backed 3D geomat will save the installation cost as well as reduce the environmental damage risks.

Water Filtration

The open structure of 3D Drainage Geomat allows for a high rate of water permeability allowing water to flow through without being clogged. It also prevents soil from being washed out by heavy water, reducing the risk of foundation dampness and erosion.

It is ideal for use in slopes as it can provide drainage and soil stabilization, avoiding the formation of slumps or mud lands. It can also serve as a filter layer around water bodies like rivers, embankments, ponds and lakes, protecting the soil from silt erosion and increasing water permeability.

Water filtration also helps to reduce the upward displacement of composite drainage material groundwater levels in areas susceptible to sinkholes. Unlike granular materials, 3D Drainage Geomat doesn’t float in water and is therefore less attractive to rodents and bacteria.

Mar-flex’s Eco-friendly Geo-Mat+ Drainage Board is designed for the next generation of waterproofing needs. It channels away below-grade moisture, protects spray-on waterproofing membranes from damage and reduces hydrostatic pressure in structures by channelling water towards footer drainage systems. This drainage mat is perfect for a range of applications including highways, tunnels and landfills where a high level of moisture protection is required.


3D Drainage Geomat is a new-type seed planting material which can prevent soil being washed away, increase the greening area and improve the environment. As a three-dimensional structural geotechnical synthetic material, it is applied to keep water and land, control erosion, linear protection, and also in construction projects’ special application.

Before grass seeds are planted, it can protect the surface of the ground firmly and evenly from wind and rain rushing in. After the seeds are sprinkled, the black geomat can absorb a large amount of heat, increase ground moisture, accelerate seed germination and prolong the plant growth period.

The open structure of the geomat makes it easy to install, and the void space of over 90% encourages plant root growth. It can be used in a wide variety of slopes, such as channel and river slopes, dam spillway slopes, rocky, soil steep slopes and other slope areas that need erosion control measures.

There are a variety of 3D geomats to choose from according to the conditions on the project site, such as the type of climate in the region, local weather conditions and exposure to wind, rain, hydraulic loadings or sun, the soil type and incline of the slope. Geomat can replace concrete, asphalt and stone slope materials. It is a cost-effective and environmentally friendly solution.
