Hello
We have a new build and are struggling with waterlogging in the garden.
The soil is very clayey and contains a lot of peat.
To address the waterlogging, we want to drill drainage holes about 1.8 to 2.4 meters deep (6 to 8 feet), deep enough to break through the clay layer.
After that, we plan to fill the holes with sand to sustainably loosen the clay so that water can drain better.
The problem is that the soil contains many stones at a depth of about 40 to 80 centimeters (16 to 31 inches) before the clay layer begins.
Our 200mm (8 inch) earth auger cannot get through the stones.
What can we do to remove the stones?
How can we remove the stones without having to dig up the whole garden?
Is it possible to remove or crush the stones locally around the holes?
Thank you for your help.

(...) Is it waterlogging? Or something else? High groundwater? Layered water?
The water present underground doesn’t stop at your property boundary.
If you build infiltration there now, the water could simply flow in from neighboring properties or the entire catchment area in the worst case. Then you would invest a lot of money and effort but gain nothing. In the worst case, you would be trying to drain tens of thousands of square meters through just a few holes 😀
Can water infiltrate below the clay layer? How thick is the clay layer? What lies beneath it?
Or is there possibly standing water or groundwater as well? Then nothing will infiltrate at all.
We have a similar problem here. From mid-November, water stands up to 50 cm (20 inches) below ground level until March. That’s just how it is and nothing can be done.
