Question:

The difference between the overlap length and the overlapping width of the geotextile in reinforced embankment

The difference between the overlap length and the overlapping width of the geotextile in reinforced embankment

Answer:

The installation of geotextiles is usually done by means of overlapping, stitching and welding. The width of the stitching and welding is generally 0.1M or more, and the overlap width is generally more than 0.2M.
Overlap length is two piece of geotextile overlapping length. The width of the lap joint is generally used for the lap joint. But sometimes the words on the books are not rigorous, and they may not be able to distinguish between the length and the width.
The geotextile, which may be exposed for a long time, should be welded or stitched. All stitches must be carried out continuously (for example, point seams are not allowed). Before stitching, geotextile must overlap at least 150mm. The minimum distance of needle selvage (material exposed edge) is at least 25mm.
