Product Introduction
Geotextile bag is a continuous (or separate) bag-like product made of a double-layer polymeric synthetic material. The application of geosynthetics in engineering is a new technology developed in the past two decades. It was introduced into China and developed and used in the late 1970 s. Mold bag concrete is filled with concrete or cement mortar by high-pressure pump into the mold bag. The thickness of concrete or cement mortar is controlled by the length of hanger bar bag and hanger bar rope (polymer such as nylon, etc.) in the bag. After consolidation, concrete or cement mortar forms a plate structure or other structure with certain strength, which can meet the needs of engineering. As a new type of building material, geotextile bag can be widely used in river, river, lake and sea dam slope protection, bank protection, harbor, wharf and other protection projects.
Product Advantages
◎ The construction of the soil mold bag adopts a spray irrigation molding, the construction is simple and fast.
◎ Geotextile bag can adapt to all kinds of complex terrain, especially in deep water revetment, bottom protection, etc. without filling cofferdam, can be directly underwater construction, high degree of mechanization, large surface area of revetment, strong integrity, good stability and long service life.
◎ The soil mold bag has a certain degree of permeability, after the concrete or cement mortar is poured, the excess water seeps through the fabric gap, which can quickly reduce the water-cement ratio, accelerate the solidification rate of concrete, and increase the compressive strength of concrete.
Mold bags are divided into the following 5 kinds:
1. Composite mold bag 2. Hinge mold bag 3. Rectangular mold bag 4. Ring mold bag 5. Grass planting mold bag

The mass per unit area is the weight of the minimum forming thickness and increases with the increase of the forming thickness.
The thickness is generally based on 150mm, and the first 50mm is a product grade.
2. Fluctuate within the control range, but not below the minimum value.
3. The final molding of the mold bag of our company shall be made according to the engineering design requirements, and the engineering unit shall provide the design drawing or sewing drawing and relevant dimensions.
