Drainage safety

The orifice is located in the trough. Due to the two-way action of the wave crest and the filter fabric, the orifice is not easily blocked, ensuring the smooth flow of the water permeable system.

Corrosion resistance

Plastics are less prone to rust than soft spring drains.

Strength and flexibility

The unique double corrugated structure effectively increases the external pressure strength of the product, and the drainage system is not affected by external pressure deformation and affects the drainage effect.

Economic type

Compared with other drains of the same diameter, the price is lower.
