You should be able to put a tape measure down the piles and confirm they all go to the correct depth - what depth is natural ground?

Which Slab is Better? Waffle Pod or Raft Concrete Slab???

When I first started out in Perth and we got clay the consutling engineer I worked for would recommend removing 600mm and replace it with sand. We would specify that…
