Lowering area with clay soil
Just looking for advice on a bright idea I had to lower an area 9ft by 9ft and 1 ft deep at the end of our garden which was previously under a concrete slab.
Since digging the 'hole' average rainfall has took about three days to drain away but the nonstop rain we've had lately won't budge and i've been having to bail it out.
I was planning to put a couple of drain pipes under there to route the rainwater away before topsoiling and turfing, but not sure if this is necessary or worthwhile?
The claysoil is very swampy now and like quicksand! I'm hoping it will dry out one day but no doubt it will throw it down again soon and I'll be back to square one. Any tips on speeding up the drying out process or should i just write it off as a stupid idea?
Any advice appreciated!
