Basic Requirements for Geotextile Laying
a. The seam must intersect the slope line; where it is balanced with the foot of the slope or there may be stress, the distance of the horizontal seam must be greater than 1.5m.
b. On the slope, anchor one end of the geotextile, and then lower the coiled material slope to ensure that the high quality polypropylene nonwoven geotextile remains tight.
c. All geotextiles must be pressed with a sand bag. The sandbag will be used during the laying and will be retained until the top layer of the material is laid.
Geotextile laying process requirements
1. Grass-roots inspection: Check whether the grass-roots are flat and solid. If there is a foreign body, it should be handled properly.
2. Trial shop: According to the site conditions, determine the size of the geotextile and test the shop after cutting, the cutting size should be accurate.
3. Check whether the width of the salar is appropriate. The overlap should be flat and tight.
4. Positioning: Use a hot air gun to bond the overlapping parts of two geotextiles, and the distance between the bonding points should be appropriate.
5. The suture should be straight and the stitches should be even when suturing the overlap area.
6. After sewing, check whether the polypropylene nonwoven geotextile manufacturers are laid flat and whether there are defects.
7. If there are unsatisfactory phenomena, they should be repaired in time.
