Ditch Lining Material
1.Rapid Solidification and Early Strength
Starts solidifying within 2 hours after water contact, achieves C15 concrete standard (compressive strength ≥15MPa) within 24 hours, and reaches C30 (≥30MPa) at 7 days, suitable for emergency repair projects.
2.Excellent Waterproof and Anti-seepage Performance
The composite structure of high-density fibers and cement forms a seamless anti-seepage layer with a permeability coefficient ≤10⁻⁷ cm/s. It can replace geomembranes for anti-seepage in canals and ponds while providing load-bearing capacity.
3.Crack Resistance and Durability
High-strength fibers enhance toughness, with a flexural strength of 5MPa, enabling adaptation to slight foundation settlement without cracking. It has strong weather resistance, suitable for extremely cold or high-temperature regions.
Product Introduction:
Ditch Lining Material is a flexible roll material composed of high-strength fibers (such as polypropylene or fiberglass) and special cement/additives through a needle-punching process. Its core structure consists of cementitious powder sandwiched between two layers of high-strength fiber mesh fabric. Upon hydration, the cement hardens to form a solid yet flexible matrix that combines the performance of concrete with the pliability of textiles—enabling rapid installation without traditional formwork or pouring methods.

Application Areas
Product Advantages
The durability of the canvas of concrete performs well in medium - load, non - extreme environments (with a normal service life of 10 - 20 years), and it is especially suitable for short - term emergency projects, water conservancy seepage prevention, and building waterproofing scenarios. However, in long - term open - air, high - load, or highly corrosive environments, its durability is weaker than that of traditional concrete. Therefore, it is necessary to improve the service life through material modification and construction protection. When making a choice, a comprehensive assessment should be carried out according to the project cycle and environmental conditions, and if necessary, it should be used in combination with traditional materials.
