Bigger is not better. Diameter × length is the product. The published enquire band on coir logs is about 15–50 cm × 3–6 m. Fill is coir fibre. Outer net, dry weight, and pieces per 40’HC stay as dashes or per-lot rows until a mill sheet fills them — this note will not invent a count.
The net is a second spec. A net that fails in a UAE yard is a different failure from a log that was the wrong diameter for the channel. Geotextiles hold the face. The log takes the first energy at the toe.
Name the project type on the enquiry: slope, channel, shoreline, or landscape. Do not send a lifestyle photograph. Erosion is the floor.
