Construction can compact soil, remove or bury topsoil, bring subsoil or fill to the surface, and leave debris or abrupt layers in the root zone.
Inspect before buying
Dig several holes and determine usable soil depth, compaction, abrupt layers, standing water, debris, and grade.
Then choose the remedy
The project may require amendment, complete soil, compaction remediation, drainage or grading work, or a combination.
Surface appearance is not enough
A thin attractive layer can hide a poor root zone. Determine the depth and continuity of usable soil.
Diagnose first, then choose the remedy
A wet, compacted or disturbed site may need investigation before it needs material.
