Long story short - newbuild House in 2014, due to heavy clay soil, during the past 3 winters the bottom half of garden has become very very boggy, lots of moss growing and lawn is unusable.
Have tried hollow tine aeration, top dressing with sand etc, with little difference. So decided I would dig a few sumps using an 8” Petrol driven auger, with the plan being to fill them with stones, then top off with topsoil and seed.
However, I’ve drilled three holes, each about 12-18” deep. The clay was very heavy, even stopping the auger turning several times. To test what the drainage was like, I emptied a gallon of water into each hole yesterday evening, and was dismayed to see how slowly they drained (if it all).
So, filling with stones/sand is unlikely to help the waterlogging if the ground is this impermeable. So what next? Any advice appreciated.
