Soft Permeable Tube

1.High permeability 2.Big tonnage 3. flexibility

Brief Introduction

 

Soft Permeable Tubeis also calledSteel-plastic flexible permeable hose ,is a new type of pipe used for inverted filtering and drainaging.

It is made of steel wire(coated PVC)+PET non-woven cloth+PET filament fiber.

Besides,PET non-woven cloth works as a filter to prevent the sand and soil from going into the pipe,thus purifying the water.

Terylene threads on the outside surface enables the pipe to have a good sopping capacity and collect the superabundant water in the soil system.

It’s mainly used in different kinds of roadbeds,square,ditch,retaining walls,tunnels to drainage.
