This picture shows just how deep we dig, to put in a proper base. We had run in to problems here and needed to put a geo-tech cloth down to help stabilize the soft clay base and now we are covering it with recycled B gravel.
Here is another picture of the geo-tech cloth
job covered with recycled B gravel, as you can see it is a lot deeper than your average depth of 12" and shows the extent we go to for our customers to prepare for an adequate base.
When we do the job right it reflex's on all of us!
