Product Description

 

Railway Geotextile Drainage Fabric High Strength / Filter Geotextile

 

 

Quick detail:

 

Material: PP or HIPS

Applications:highway and railway

According to customer requirement

 

 

Description:

 

Drainage plate is made of polystyrene (HIPS) or polyethylene plastic. to prevent the soil particles through, it cement filter geotextile on top surface, so as to avoid blocking and make the hole channel smooth. Traditional drainage uses brick tile, more pebbles and gravel as a filter layer, which drains away water to

designated spots. Drainage plate will save time, energy, investment, and also can reduce the load of the building.

 

 

Features:

 

1. Vertical and horizontal reinforcing ribs are provided to significantly improve the strength of wall support of water-pervious pipe.

2. A frame with vertical and horizontal reinforcing ribs is provided outside the wall support. Polyester Filament yarns are wound in this frame and form a complete unit so that the water pervious layer has better strength and is not easily deformed or crumpled.

3. The water-previous pipe with reinforcing ribs may effectively block bulky soil lumps or gravels from breaking though the coating to ensure both filtration and water permeation. It can also effectively prevent damage to the thrust from working equipment. Meanwhile, it has excellent filreation and water permeation to ensure more reliable water discharge.
