compacted base

A compacted base is a layer of soil or crushed stone that has been pressed down so it is firm and stable. It sits under a container to carry the weight and resist settling. Conexwest notes that some sites need compaction, stone, piers or professional soil review before placement.

Why it matters

Soft ground can let one corner of a container sink, which can twist the frame and make the doors hard to open. Compacting the base lowers that risk. Equipment such as a plate compactor or roller does the work, and the soil must be graded first. A common mistake is to think a lawn is firm enough. Grass over soft soil often is not, and wet weather makes it worse. Operators may refuse a drop if the ground looks unsafe for the truck. Customers should ask what base the provider expects for their unit and their soil.
