3D Drainage Geomat

3D Drainage Geomat represents a paradigm shift in drainage technology, reducing the ecological footprint of infrastructure projects and preserving natural landscapes. Compared to traditional drainage methods like perforated pipes or gravel-filled trenches, it provides greater versatility and adaptability across different soil types, terrain configurations, and hydraulic conditions.

The innovative triplanar netting structure allows plant roots to effortlessly penetrate into the mat, forming a green composite layer that guards against erosion.

Efficient Water Drainage

Drainage geomats are an excellent alternative to traditional drainage systems, such as perforated pipes and gravel-filled trenches. They efficiently channel water through a unique matrix structure, minimizing water saturation and sedimentation in soils and preventing erosion in sensitive areas.

Depending on the project’s needs, there are several types of drainage geomats 3D Drainage Geomat available. Each one is designed to serve a specific purpose. For example, fireproof geomats are used in projects requiring fire risk protection, while permeable drainage geomats are ideal for sustainable drainage.

The efficacy of a drainage system is highly dependent on the site’s soil type, slope gradient, and hydraulic conditions. 3D drainage geomats are designed to work well with a variety of soil types, reducing construction-related disturbance and allowing natural vegetation to grow in the vicinity of the installation. This is in accordance with environmental sustainability goals, ensuring that projects do not adversely affect local ecosystems. Additionally, the material helps to stabilize soil particles and promotes plant establishment, preventing soil erosion and land degradation in vulnerable areas. This prevents landslides and reduces the need for costly rehabilitation or reconstruction.


It can prevent soil erosion caused by wind and rain, preventing damage or pollution to natural landscapes. Moreover, it can offer long-term and full-scale reliability in various applications.

3D drainage geomat has an advantage over traditional drainage systems that use perforated pipes or gravel-filled trenches in preventing erosion of the soil. The geomat’s three-dimensional structure enables vertical and horizontal water drainage, thereby minimizing the need for extensive excavation and construction-related disturbance of the surrounding natural landscape.

This innovative material is used in landfills to collect and channel leachate away from waste, reducing the risk of contamination of the surrounding soil and groundwater. It is also employed in environmental remediation efforts to improve soil aeration, prevent waterlogging, and promote plant growth.

It is a kind of black, three-dimensional net like, towel gourd-shaped, waterproof, polymer geosynthetic material. The core is made of compact 3D PP or PA mat and compounded with non-woven fabric on one side or both sides, which ensures gas venting, separates the fill from the core, increases its tensile strength and protects it from being washed out by heavy water. It can be reinforced with hexagonal wire mesh or geogrid to increase the integral stability.

Stabilizes Soil

Erosion of soil from slopes or embankments easily results in damage or pollution. The erosion force is caused by wind, rain or hydraulic loadings. Although naturally growing vegetation can help reduce the erosion force, it cannot offer long-term and full-scale reliability due to its limited retention qualities. 3D geomat erosion control mat protects the soil from erosion and is able to provide long-term stability.

Hexagonal wire mesh and geogrid reinforced 3D PP geomat improves shear resistance and stabilizes the soil. It can be used as a reinforcement layer for road, railway, tunnel and other construction projects.

3D drainage geomat can be buried along the slope, and then filled with gravels or soil. Then, compact it to ensure that it perfectly fits the slope surface. The drainage geomat will prevent the slope from collapsing or dispersing soil during heavy rainfall. It also improves the stability of the roadbed and pavement. It is also a useful construction material for linear protection and environment recovery projects. In addition, it can be used as a fire risk protection material.

Reduces Construction-Related Disturbance

Drainage Geomat helps minimize construction-related Bentonite waterproof liner disturbances by redirecting water, which reduces hydrostatic pressure that could damage below-grade waterproofing membranes. It also helps prevent erosion and sedimentation by protecting slopes.

3D drainage mat takes compact 3D PP or PE net as matrix, compounded with non-woven geotextile on one side or both sides. It can collect the rainwater or sewage discharged from the wasteyard through the soil cover layer and discharge it orderly according to the engineering requirement without silting. It can also discharge methane gas that is produced from fermentation in the soil (especially waste waste), thereby preventing the accumulation of toxic gases.

3D Drainage Geomat is an ideal solution for a wide range of applications, including slope stabilization, linear protection and environmental recovery. It can also be used to stabilize and reinforce spray-on waterproofing, thereby helping to protect it from the effects of hydrostatic pressure. Mar-flex Waterproofing & Building Products offers both Geomat and Geomat+, which is designed to offer added protection with an additional layer of geotextile fabric. This feature makes the latter a more versatile option for a wider variety of applications, including soil filtration.

Long-Term Soil Stabilization

3D Drainage Geomat is a three-dimensional network like towel gourd net mat for grass planting and soil consolidation. It has loose and flexible texture with 90% space for filling earth, gravel and fine stone so that plant roots can go through it easily and grow orderly. After grass grows, the mat, soil surface and turf can be combined firmly. This can form a solid green composite protecting layer that can stand the erosion of heavy rain.

The HDPE geomat fabric absorbs a lot of heat energy and enhances ground temperature, which can promote seed germination and speed up the growth of plants. In addition, it can prevent damage and pollution caused by soil washed away from slopes, embankments or channels.

Once vegetation covers the slope, it can withstand water flows(up to 4m/sec) which is twice that of ordinary turf. It can also improve the slope shear strength and reduce pore water pressure and self-gravity to make the soil more stable. Moreover, the geomat increases the shear strength and cohesion increments caused by root-geomat mutual interlocking.
