• One-to-one labeling and installation diagrams can be provided; 

• Customized outer box and printed outer cloth service are provided (MOQ minimum order).

FAQ；

How much pressure can the drainage cage withstand? Is it easy to deform?

Answer: High-quality drainage cages use high-strength HDPE or galvanized steel wire as the skeleton material, and its compressive strength can reach 100-400kPa, which is suitable for general fill, traffic load and even the construction environment behind the tunnel. As long as the construction is reasonable, it is not easy to deform or collapse.

Can the size and shape of the drainage cage be customized?

Answer: Yes. We support customization of the following parameters:

• Length: 0.5m-3m;

• Diameter/width: 100mm-600mm;

• Structural shape: round, square, U-shaped, etc.;

• Wrapping type: non-woven fabric, woven fabric, mesh bag, etc.;

• Filling type: crushed stone, ceramsite, plastic ball, etc.

Will the wrapping layer of the drainage cage be broken by water flow or blocked by soil?

• Answer: No. The outer covering material of the drainage cage is a special geotextile or woven mesh, which has good tensile strength and durability, and has an appropriate pore size, which can effectively filter fine particles and prevent blockage and breakage.

What should be paid attention to during transportation and storage?

Answer:

• Drainage cages are light in weight and compact in structure, and can be stacked for transportation;

• PE film + strapping or pallet loading is recommended for packaging;

• Storage should be kept away from direct sunlight for a long time, and it is recommended to be placed in a cool and dry place;

• Prevent sharp objects from puncturing the outer geotextile.

Do you provide OEM service?

Answer: Of course. We can provide the following according to customer needs:

• LOGO customization;

• Packing bag printing;

• Export box labeling;

• Exclusive instruction manual or construction manual printing.
