Strip and Replace

A soil grading technique which involves the following:
a) Remove the topsoil, stockpile it by stacking in a heap, and then replace it after levelling of the subsoil has taken place. There is always a slight assumption that the topsoil is suitable for being placed back onto the graded subsoil; or
b) Remove the top-soil and use it for other purposes, then grade the existing subsoil to the desired evenness and then import new topsoil or rootzone material.
