In this reference, the soil was first backfilled with gravel and vibrated firmly with a vibrating machine. Then the gravel honeycombs were laid. They were fixed in the ground with BA230 ground anchors. This gives the honeycomb mats even more hold and prevents them from slipping.
As a last step, the honeycombs must be filled with gravel, here we recommend crushed material. Round gravel is very unsuitable for this project. Finally, the honeycombs or gravel should be fixed with a vibrating machine.
