I been doing my driveway last week and rain stopped play and been like it since due to soil being really wet. my question is when can i start again as it drying out most of the area can support all 20st of me without sinking its only the middle where i sink about 3-4 inch's and about 5 mins later you can see water appear. could i replace the really wet soil with dryer soil that i already dug out?
