Building a roadbed is like laying a foundation for a building. If the roadbed is well repaired, the road surface will not crack and settle. As the saying goes, there is a cause and effect, and a good roadbed can withstand the rolling of heavy-duty and large vehicles, and the road surface is strong and durable. So, how to choose a suitable subgrade geogrid? Today, Feicheng Tiancheng Engineering Materials Co., Ltd. will answer this question in detail for you, and teach you how to choose a suitable subgrade geogrid, so as to ensure that you will not spend any money in the procurement process!

First of all, we have to look at the construction environment, whether it is an ordinary inland road or a seaside wharf. If it is the former, we can use a cost-effective steel-plastic geogrid. This kind of roadbed geogrid can reach more than 100 kn, while The price is nearly half cheaper than the plastic two-way geogrid of the same strength. While ensuring the construction quality, it costs less. The main thing is that its ultimate strength is high, and it can better play the role of the roadbed, especially in coal mines and steel factories. In this way, it is necessary to take the road of super-heavy vehicles, and steel-plastic geogrids are used to open and strengthen the roadbed. For the coastal wharf subgrade, plastic two-way geogrid is often used, because this kind of grid is made of polypropylene or polyethylene plastic, she is not afraid of water, especially for some reclamation projects, use it to form gabion nets Full of stones thrown into the sea for reclamation, especially corrosion-resistant.

Secondly, we need to choose according to the size of the crushed stone of the construction filler. The mesh size of the steel-plastic geogrid is generally 10-14 cm square, and the plastic geogrid (two-way) is 4 cm square mesh. Stone size, if the crushed stone is large, we recommend using steel plastic, if it is small gravel with a diameter of less than 3-4 cm, it is recommended to use plastic two-way geogrid.

Well, the above are the two golden rules for choosing a suitable roadbed geogrid. If you have any questions during the procurement and construction process, please feel free to call us, and we will answer you in detail! Feicheng Tiancheng Engineering Materials Co., Ltd. looks forward to cooperating with you!

We must make it clear that the extensibility of the geomembrane is very important, and we must improve the extensibility in a timely and targeted manner, so that we can better improve ourselves reasonably.

The main function of geomembrane is to integrate anti-seepage and drainage into one

The characteristic of geomembrane is that the intersection of warp and weft is not curved, and each is in a straight state. Bind the two firmly with a binding wire, which can be more evenly synchronized, withstand external forces, and distribute stress. When the external force is applied to tear the material, the yarn will gather along the initial crack to increase the tear resistance.

Market demand for geotextiles

Now many people are paying attention to this issue, because many large enterprises and construction teams now have a great demand for this kind of material. Generally speaking, if there is demand in business, there will be supply. If people need to get involved in a professional field, So the first question that people need to figure out is whether this industry field is already in a full state, and is there a large demand for this product?

Since my country introduced geogrid products from abroad in the 1990s, geogrid manufacturers have sprung up all over the country, among which Jiangsu Province was the first, and then Shandong Province. Starting with Jiangsu Province as the birthplace of geogrid manufacturers, Shandong Province began to make efforts around 2000, and a large number of geogrid manufacturers invested and built. After 2010, other provinces such as Hebei Province, Sichuan Province, Gansu Province, Xinjiang, and the three northeastern provinces also began to invest in some low-cost geogrid equipment.
