It is recommended that a barrier such as Filter Fabric be placed on the ground before laying the gravel. This will not only help to keep the Glacier Boulders from being pushed into the soil, it will make it much easier to remove the Glacier Boulders should you want to do so.

- Large River Rock is not recommended for construction purposes due to its round shape.
