I would like to put a brick paver patio in my backyard, and I have done the research regarding the amount of aggregate and sand that needs to be placed under the pavers to keep them stable. I figure I will need to dig about 6 - 8" into the ground and begin layering my aggregate etc.
Trouble is, I have a rather large pine tree right against the side of one of the edges of the patio, and am not sure how deep I can dig before hitting the roots. My guess is about 4" before hitting them.
Can I dig down the shallow and still put the required amount of aggregate - which will bring the patio 4" above grade. I can easily put more soil around the edges to "smooth" out the difference to make it look aesthetically pleasing. But I am not sure if this will present issues with freezing during the winter.
Looking for some advice!
Thanks.
