HDPE geomat fabric is a new type of geosynthetic material with three-dimensional structure suitable for soil and water conservation, which can effectively prevent soil and water loss, increase green area, and improve the ecological environment.
1. What Is HDPE Geomat Fabric?
HDPE Geomat fabric is versatile materials used in civil engineering and environmental applications. Made from High-Density Polyethylene (HDPE), these three-dimensional structures provide stability, reinforcement, and erosion control in various soil and water management scenarios.
Characterized by high strength, durability, and resistance to chemicals and UV radiation, HDPE Geomat form stable and permeable matrices through weaving or knitting. Their open void structure enhances soil retention, drainage, and erosion resistance.
These fabric are commonly employed in erosion control, stabilizing slopes, riverbanks, and erosion-prone areas to prevent sediment loss. They also reinforce soil in geotechnical projects, improving load-bearing capacity and stability.
HDPE Geomat fabric are suitable for hydraulic applications like protecting channels and riverbanks, allowing water passage while preventing soil erosion. They also support vegetation growth by providing a stable substrate, promoting environmental sustainability.
In landfill construction, Geomat fabric act as liners, containing waste materials and preventing harmful substance leaching. They are also used in pond and reservoir linings to prevent water seepage and soil erosion.
BPM brand HDPE Geomat fabric, composed of synthetic filament materials, offer high deformability and porosity. Widely used for road, railway, river, dam, and hillside protection, they work with geotextiles or geomembranes to convey drainage. These fabrics shield land from wind and rain before vegetation growth, and the resulting protective layer withstands high water levels and flow velocities. Additionally, they exhibit superior chemical stability and do not pollute the environment due to their polymer composition and UV anti-ultraviolet stabilizers.
BPM HDPE Geomat fabric play an essential role in geotechnical and environmental engineering projects, providing effective solutions for soil stabilization, erosion control, and sustainable land use practices.
2. Why Chose HDPE Geomat Fabric Thailand for Highway Slope Project
Selecting BPM HDPE Geomat Fabrics Thailand for the Highway Slope Project on the Pingguo to Nanning section of the Tian’e-North Highway holds paramount significance. This stretch is a vital component of the “Ten Vertical Lines” framework within the “Guangxi Expressway Planning Network (2018-2030).” Originating in Sitang Town, Baise Pingguo City, the project encompasses Tian’e Pingguo-Jingxiang, Long’an Bubei County North Pier North Pier Road, and Nanning Urban Shibu Interchange, culminating in the realization of the Ben-Kun Expressway.
The establishment of the Shibu North Interchange further facilitates the connection between the Nanning Ring Expressway and the traffic flow to 4 districts, counties, and 8 townships. Spanning a total length of 84.965 kilometers, the designed speed of the road reaches approximately 120 kilometers per hour. The roadbed width extends to 34 hours and 17 kilometers, while the road length measures 23.0 meters (calculated as 2 × 15.0 meters). The comprehensive infrastructure includes 1.8 meters/57 seats, 3472.9m/6 tunnels, 5 interchanges, and 2 service areas. Opting for BPM HDPE Geomat Fabrics Thailand aligns with the project’s demands for robust and reliable materials in the execution of this critical highway initiative.

At the beginning the CCCC company visit BPM Geomat company ,BPM 16000 square meter factory and advanced production line of geomat and geotextile gave them professional impression . before we sign agreement they need we offer product brochure , ISO Certificate , SIRIM Certificate ,Test Certificate ,Project References and material safety date sheet , all they requirement BPM can offer to them.
3. How to use geomat fabric in highway slope protection project
To use geomat fabric in a highway slope protection project, follow these steps:
(1) Slope Preparation: Begin by cleaning the slope of any debris and leveling any low-lying areas by backfilling and compacting the soil. This ensures a smooth and stable slope surface.
(2) Geomat Fabric Installation:
(a) Lay the 3D Mesh: Start by laying the three-dimensional geomat fabric from the top of the slope to the bottom, ensuring a smooth connection between the fabric and the slope.
(b) Pre-Embedment: Extend the fabric by 40-80cm at the top of the slope and bury it in the soil, compacting it to provide a secure anchor for the fabric.
(c) Anchoring: Fix the geomat fabric in place by using U-shaped steel bars with a diameter of approximately 6mm. Install the steel bars from the bottom to the top of the slope, spacing them approximately 1.5-2.5m apart. In the middle, use 8# U-shaped steel bars. Additional fixation can be achieved using iron nails or bamboo nails.
⑷Covering soil After the three-dimensional vegetation net is laid, evenly cover the soil on the three-dimensional vegetation net, cover the net bag until there is no empty bag, and ensure that the thickness of the soil on the three-dimensional vegetation net is not less than 12mm. Then the fertilizer, auxin and cement are mixed evenly in a certain proportion and applied to the surface layer. The fertilizer is nitrogen:phosphorus:potassium=15:15:15 or nitrogen:phosphorus:potassium=10:8:7 compound fertilizer and organic matter containing N, and the fertilizer amount is about 30-50g/㎡.
3. Spraying. After the backfill is completed, hydraulic spraying is carried out, that is, grass seeds (sprayed at about 25 grams per square) and the adhesion agent, wood fiber, fertilizer, auxin, humectant and water that promote their growth are mixed and stirred in a certain proportion to form a uniform The mixed liquid is evenly sprayed on the slope surface by the hydraulic sprayer. settlement.
4. Overlay. After the spraying and planting is completed, the surface of the slope is covered with non-woven fabrics to maintain the moisture on the slope and reduce the scouring of the seeds by rainfall, so as to promote the growth of the seeds. If the temperature is too high, there is no need to cover it to avoid the occurrence of pests and diseases.
5. Maintenance management. After the spraying construction is completed, it must be maintained regularly until the lawn is flat. When the lawn grows to about 5cm, the non-woven fabric can be uncovered.
BPM Geomat is a new type of geosynthetic material for soil conservation which has good function on erosion control , increase of greening , and improvement of ecological environment , Its mainly used on slope protection of road , railway , river ,dam ,before the turf grow out , protect soil from heavy rain , after the plant grow a mixed protection layer , it can stand the erosion of storm , as a material with high polymer and UV stabilizer , geomat has good chemical resistance .The three-dimensional plant net building technology combines the advantages of HDPE geomat fabric and plant protection slopes, which can effectively solve the problems of rock slope and high land side technology protection. Application examples show that three-dimensional vegetation network slope protection is extremely beneficial to the stability of the slope and protects it. The effect is very good. The HDPE geomat fabric is mainly used for slope protection of highways, railways, rivers, dams, etc.
