COIR LOG
Coir log (water log, coco log) is made with a coir netted bag filled with coir fiber. Coir netted bag could be either a diamond netting or geotextile netting.
In general, the diameter is 30cm and 3m or 4m long. The weight is about 10kg/m.
The coir log is placed in river banks to prevent the river bank erosion from the wave created in the river. The pre-vegetated logs are also available.
By selecting the correct vegetation, water can be cleared instead of using chemicals.
