Short Fiber Needle Punched Polyester Geotextile/SNG350

Property:

1. Good air and water permeability-interspace in the fibers made it favorable water permeability.

2. Corrosion resistant-geotextile is made from polyester,featuring resistance to acid and alkali ,non-corroding,no worm-eaten,anti-oxidation.

3. Good water transmissibility and filtration- it can form drainage channels inside soil mass to drain redundant water and air out of the soil mass.

4. High intensity-geotextile can keep sufficient strength and elongation in dry and wet condition due to the use of plastic fiber.

5. Easy construction,low weight,easy operation,simple construction

Function

1. Isolation

Short fiber needle punched geotextile can prevent the mixture of construction

materials featuring different physical properties (such as soil mass and sandstone,soil mass and concrete)

2. Filtration

Its good water and air permeability let water flow through it so as to effectively control

sandrock running down.

3. Reinforcement

Geotextile helps to enhance the soil mass tensile strength and non-deformability and structural stability so as to improve soil mass quality.

4. Protection

It can effectively make the concentrated stress diffuse,transfer or decompound,and guard the soil mass against the destruction of external force.

5. Anti-puncture

Combine with geomembrane and form compound waterproofing material to act a part of anti-puncture.
