Insulation Non-Woven Filter Polyster Non Woven Nonwoven Geotextile Fabric with High Quality

 

POLYPROPYLENE SHORT FIBER NEEDLE PUNCHED GEOTEXTILE

• Product Introduction:

Using ultra-high-strength polypropylene staple fiber or ES fiber as the main raw material, it is produced by non-woven technology and has the functions of isolation, reinforcement, protection, filtration, drainage, and buffering.
Product specifications: PP100~PP1200, width 2m~6m., length according to user requirements.

• Features:

The physical and mechanical properties are 2 to 3 times higher than that of conventional products. The proportion of products with the same gram weight is low; the acid and alkali resistance is excellent, the hot melt adhesion is good, and the wear resistance is strong. It is more suitable for CRTS/ slab ballastless track sliding layer system, which can reduce the interaction between the track system and the bridge surface.

• Applications:

Polypropylene needle-punched non-woven geotextile is mainly used for the sliding layer between CRTS slab ballastless track and beam surface of passenger dedicated railway, and the isolation layer between CRTS slab ballastless track and friction. It can also be widely used Hydropower, highways, railways, ports, airports, sports venues, tunnels, beaches, reclamation, environmental protection and other fields play the role of isolation, filtration, drainage, reinforcement, protection, etc.

Geotextile Application

How to install  geotextile fabric

Let us show you how easy the installation is and provide a few useful tips along the way. In our example,

Step 1 - Prep the road surface

First, you will need to excavate the roadway to the desired elevation. Then fully compact your subgrade, making sure you have removed all air and tightened the soil completely.

Step 2 - Unroll the reinforcement geotextile fabric

Roll the geotextile fabric on the compacted subgrade, making sure it's free of wrinkles and folds. Overlap your fabric as directed by the engineer. Cherokee can pre-sew the fabric for you if a stitch seam is required. Contact your Cherokee representative to get pricing on factory seamed rolls in a wider widths.

Step 3 - Sew the geotextile fabric

This job required the fabric to be stitched on the job site. The fabric needs to be seamed with a dual thread lock stitch to prevent it from unthreading. We have equipment available for purchase or rental to do the stitching on the job. At the engineers discretion you can choose a prayer seam, j-seam, or butterfly seam. In this example we will be using a j-seam. We recommend doing two stitches on each seam to prevent any failure during installation.

Step 4 - Apply Aggregate

Place your aggregate to the specified thickness, ensuring that no equipment drives directly on the engineered fill. Make sure the fill has reached full compaction before the final step.

Step 5 - Lay Asphalt

Now that you have placed your subbase you are ready for your pavement layer (or layers depending on the project type).
