Laying a block pave driveway, when sub base dug out we discovered soft spots which we dug out and thought we stabalised with extra 6 inches of crusher run compacted, this was solid and we then laid a geotextile on top before laying subbase (5 inches). All ok until heavy rain, these soft spots are just like sponge again, have been advised they will firm up, is this the case?? We were considering digging out again an pouring concrete in to stabalise, any thoughts?
