BPM is the one of the largest geogrid suppliers in China. Our biaxial geogrid is made of high molecular polymer through extrusion lamination stamping into a regular mesh and then stretched longitudinally. The material has great tensile strength in the longitudinal and transverse directions. This structure can also provide an ideal interlocking system for more effective force bearing and diffusion in the soil, and is suitable for large-area permanent load-bearing foundation repairs. powerful.
Since the polymer polymers of the bidirectional plastic geogrid will rearrange their orientation during the heating and elongation process, the bonding force between the molecular chains will be strengthened to achieve the purpose of improving its strength. We add anti-aging materials such as carbon black to the geogrid, which can make it have better durability such as acid resistance, alkali resistance, corrosion resistance and aging resistance.

Issue
Thailand is a dynamic Southeast Asian country that has been investing heavily in infrastructure, especially the highway network. The country’s diverse geography, combined with changing weather patterns, presents unique challenges for highway construction and maintenance. Therefore, geotechnical materials such as bidirectional geogrids are becoming more and more important. The widespread use of geogrids in highway construction in Thailand is mainly due to the country’s need for a durable, sustainable and cost-effective road network. This, coupled with Thailand’s climatic conditions characterized by strong monsoon seasons, often leads to soil instability, frequent landslides and highway erosion. These conditions pose a significant threat not only to the structural integrity of the highway, but also to the safety of road users.
In addition, the geographical diversity of northern Thailand’s mountains, river valleys, and coastal plains results in different soil types and conditions. This diversity compounds the challenges of highway construction and maintenance. It is critical to mitigate these issues and extend the life of highways. As the best geogrid suppliers, we at BPM have received the above feedback from Thai customers on the current status of Thailand’s roads and made an inquiry for the geogrid produced by BPM.
Solution
During the research process of geogrid production, our BPM considers how to improve the stability of the roadbed and prevent settlement when building highways on soft soil foundations. As a new construction material, geogrids can provide soil stabilization, where their interlocking design enhances load distribution over a wider area and can reduce the pressure exerted on the underlying soil layer. We at BPM take into account that landslides often occur due to the influence of Thailand’s monsoon climate. And the geogrids produced by BPM are exactly that to mitigate landslides, in hilly or mountainous areas, geogrids are used to stabilize slopes and prevent landslides, which is a common problem during the monsoon season. They provide additional reinforcement and help maintain the structural integrity of the highway. After we recommended plastic two-way gratings to Thai customers that could solve the problem of road subsidence. The customer sent us photos of the project site, and based on our export experience, we recommended the BPM 35-35 specification geogrid to the customer. Clearly understand customer needs and propose perfect solutions. Arrange samples, testing and production for customers at the first time and put forward our installation guidance. We as the geogrid suppliers have won the trust and support of customers with our professional customized services.

Benefits
Plastic Biaxial Geogrid has the following advantages:
It has the advantages of high strength, good toughness, light weight and long life. Geogrids are generally considered to be stretched mesh materials with a tensile strength greater than 12kN/M. It is made of hot plastic after strict proportioning, extruded or stamped into a net, then quenched, and then slowly heated and stretched to make the molecular chain highly oriented along the stretching direction. Because of its high degree of tensile orientation, the tensile strength of geogrid can be as high as 100~200MPa. The mesh elongation is small, only about 4%~10%, which is close to the level of low carbon steel. It has a strong mesh structure. It is an ideal structural mesh material. Bidirectional geogrid can distribute loads evenly. It strengthens soft soil through two important mechanisms: direct tensile stress and lateral displacement of peripheral soil. For example, the geogrid is directly installed on the soft foundation, and then supplemented with a granular base layer. This not only ensures that the granular materials and the foundation soil do not mix, but also further strengthens the interlocking effect between the mesh grid and the granular materials, and the base layer is resistant Tensile strength, thereby improving the bearing capacity of soft soil foundation.Good sub-base reinforcement.
The Plastic Biaxial Geogrid has a high friction coefficient and strong tensile capacity, which can enable the soft soil foundation to bear a large load in a short period of time, thereby greatly speeding up the filling speed and shortening the construction period of the project. The economic value of using two-way geogrid lies in: It reduces the requirements for filling materials. Reduce the cost of earth filling and rolling. After reinforcement, the thickness of paved soil can be increased, and the number of rolling times can be reduced, thereby reducing the cost of rolling.
Solving settlement problems: In areas with soft or compressible soil, geogrids help control uneven settlement, a common problem that causes road deformation and damage. Incorporating them into the construction process improves load distribution, reduces uneven settlement and extends the service life of highways.Erosion control.
Improve pavement performance: Geogrids can also improve the performance of highway pavement by reducing ruts and cracks, resulting in a smoother and safer driving experience.
In short, the use of Plastic Biaxial Geogrid on conditional soft soil foundations not only has wide adaptability in technical applications, but also has considerable economic benefits and broad application prospects.
Summary
The characteristics of Plastic Biaxial Geogrid are high strength, low elongation, and high temperature resistance. It is used at the junction of highway asphalt paving layer and roadbed. It can strengthen and reinforce the road surface, prevent road cracks and reflective cracks, and can well integrate the road surface. The load-bearing stress is dispersed and the service life of the pavement is extended. The application of bidirectional geogrids in highway construction in Thailand demonstrates the integration of geotechnical engineering and infrastructure development. The unique performance and advantages of bidirectional grilles have proven to be an effective solution to Thailand’s unique highway construction challenges, promoting a safer, more durable and cost-effective road network.
