Ditch Lining Material
1.Quick Solidification and Molding: After the hydration reaction occurs upon watering, its size and shape can still be processed within 2 hours. It can harden to reach 80% of its strength within 24 hours. Also, special formulations can be used to achieve quick solidification or delayed solidification according to special requirements.
2.High material strength: Fibers play a role in enhancing material strength, preventing cracking, absorbing impact energy, forming a failure mode, and improving the overall strength and impact resistance of the concrete mat.
3.Long - term durability: It has good chemical resistance, resists wind and rain erosion, and does not undergo UV degradation in sunlight. It can be used outdoors for a long time.
4.Waterproof and Fireproof: The waterproof layer on the bottom makes it completely waterproof. At the same time, it has good flame retardant properties, meets the European flame retardant standards for building materials, does not assist combustion, generates very little smoke when on fire, and has a very low emission of dangerous gases.
5.Environmentally friendly: It is a low - quality and low - carbon technology. In many applications, the amount of materials used is 95% less than that of common concrete. The alkali content is limited, the scouring rate is very low, and it has little impact on the local ecology.
Product Introduction:
Ditch Lining Material-Concrete carpet, also known as cement carpet or concrete canvas, is a new type of building material.
Composition and Structure
Fiber Composite Structure: The three-dimensional fiber composite structure woven from polyethylene and polypropylene filaments serves as the base material. This structure endows the concrete blanket with good flexibility and certain tensile strength, making it less likely to be damaged during transportation and laying.
Dry Concrete Mix: It contains a dry concrete mix with a special formula. The main components include calcium aluminate cement, etc. Its main chemical components are Al₂O₃, CaO, SiO₂, and Fe₂O₃, which are the key to the formation of strength after the concrete blanket hardens.
Polyvinyl Chloride Bottom Liner: The bottom surface of the canvas is covered with a polyvinyl chloride (PVC) bottom liner, which plays the role of waterproofing and moisture-proofing. At the same time, it enhances the chemical resistance of the material and extends the service life of the concrete blanket.

Product Applications:
1.Hydraulic Engineering: It can be used for slope protection and anti-seepage projects of rivers, reservoirs, canals, etc., to prevent the scouring of the bank by water flow and water leakage. For example, laying a concrete blanket on the slope of a reservoir dam can effectively enhance the stability and waterproofness of the slope.
2.Transportation Engineering: It is applicable to the reinforcement of subgrade slopes of highways and railways, the protection of tunnel entrances, and the laying of temporary roads, etc. For instance, in the slope protection of mountain highways, the concrete blanket can be constructed quickly to prevent slope collapses.
3.Construction Engineering: It can be used for roof waterproofing, basement moisture-proofing, wall insulation and decoration of buildings. For example, in some simple or temporary buildings, concrete blankets are used for roof waterproofing treatment, which is easy to construct and has a good effect.
4.Agricultural Field: In aquaculture, it can be used for slope protection and anti-seepage of fish ponds, shrimp ponds, etc., to prevent pond wall collapse and water leakage; in agricultural irrigation, it can be used for the lining of irrigation channels, reducing water leakage and evaporation and improving irrigation efficiency.
5.Environmental Engineering: It can be used for windbreak and sand fixation. It is laid at the edge of the desert or in areas with strong wind and sand to fix sand dunes and reduce the impact of wind and sand on the surrounding environment. It can also be used in the anti-seepage projects of landfills and sewage treatment plants to prevent pollutants from seeping and polluting the soil and groundwater.
6.Emergency Engineering: Such as flood fighting and rescue, construction of temporary buildings in earthquake-stricken areas, soft foundation treatment, etc. In flood fighting and rescue, concrete blankets can be quickly laid to form a waterproof dam to block the invasion of floods. In earthquake-stricken areas, it can be used for ground hardening and simple protection of quickly built temporary shelters.
7.Offshore Engineering: It is applicable to projects such as submarine optical cable protection, bridge pier protection, and reclamation slope protection. Its waterproof and corrosion-resistant properties can play a good role in the marine environment. For example, it can wrap submarine optical cables to prevent them from being damaged by external forces.
Through material innovation (fiber composite + dry - mixed concrete) and process optimization, the concrete carpet breaks through the limitations of traditional slope - protection materials in terms of efficiency, cost, adaptability, and durability. It is particularly suitable for emergency projects, complex terrains, and ecologically sensitive areas, providing a more efficient and low - carbon solution for slope protection.
