My new house has a big empty area on the side. I planned to extend the backyard to fill the rear and the rest for the garden (posted a couple of days ago).
Yesterday, a truck came by to drop off the material for the extended backyard. Obviously, it was too heavy for the uncompacted sand/soil. It sunk.
Luckily, no serious harm has been done. Just some crack concrete which can be easily fixed.
Still a long way to go.
