High surface perforation rate, excellent water collection properties

The plastic blind channel features a unique three-dimensional mesh structure with a high surface porosity, exceeding 85%. It outperforms traditional blind channels with porous pipes and cylindrical mesh tubes in terms of surface water absorption and water collection properties.

2. High void ratio, excellent drainage properties

Plastic blind trench materials feature a three-dimensional mesh structure with a high porosity of over 85%, especially the hollow-shaped materials which have an even greater porosity. Due to the high porosity, the resistance to water flow is minimal, offering excellent drainage capabilities. Even under super-load pressures, when the porosity of the plastic blind trench is reduced to 50%, it still maintains significant drainage capacity.

High compressive strength, excellent pressure resistance properties.

Traditional blind channel materials often have low compressive strength, easily damaged under high pressure, leading to the interruption of drainage pathways and drainage failure. Plastic blind channel materials have high compressive strength and good resilience. Under a pressure of 250kPa, the void ratio of the cross-section remains above 60%, and it can return to its original state after the pressure is released, eliminating issues of drainage failure due to overloading or other causes.

4 High flexibility, adaptable to soil deformation

Plastic blind trench materials not only offer excellent pressure resistance but also possess flexibility, allowing them to accommodate the deformation of surrounding soil mass. This prevents the blind trench from being severed due to factors like excessive ground deformation or uneven settlement. As a result, they can avoid the failure of traditional blind trench drainage systems caused by various reasons.

5. Excellent durability

The plastic blind trench materials are formulated with anti-aging properties, ensuring stable performance and features such as UV resistance, high-temperature tolerance, and corrosion resistance. Consequently, these materials can maintain structural stability and drainage capabilities even underwater and in soil for decades.

6. Lightweight and easy to construct

The main material of plastic blind trench materials is plastic, which has a low density (approximately 0.91 ~ 0.93), high porosity, light weight, and is very convenient for on-site construction and installation. This significantly reduces the labor intensity of workers and improves construction efficiency.

7. Diverse Shapes

Traditional blind channel materials are typically circular, but plastic blind channel materials can be customized into various shapes according to engineering drainage and construction installation requirements. They can be made into circular, rectangular, trapezoidal, horseshoe, and other shapes, which is something that other blind channel materials cannot easily achieve.
