A Tree Causing a Problem?
When a tree is making a PermaCrete project and your own life more difficult, it can definitely be a problem. But not if you're Ed Thompson, PermaCrete's Dealer Advisor, such as when Ed came face-to-face with a certain huge elm tree beside a retail driveway installation.
One of the elm tree’s roots was doing an uprooting number on the driveway and had been for years. Rather than harm the tree or reroute the driveway, Ed had a better idea. He cut a 2’ x 2’ "V" section at the edge of the main slab and installed expansion joints. This allowed the "V" section to "float" as needed without cracking whenever the roots pushed upward. Ed then used a backer rod at the base of the "V" joints and filled the expansion joints with caulk to make the joints more pliable. In the highly unlikely event that the root were to break the "V" wedge, it would only be necessary to replace the wedge itself which would be easier and quicker than replacing a large portion, if not all, of the driveway slab. This same technique can be used whenever there is an obstacle complicating the symmetry and viability of a PermaCrete installation. Next month — quicksand. Ed? Ed! Where did Ed go? |
