I happened to be ready to tally forth this morning when the workmen for the cement pouring of my new sidewalk square showed up, shovels and big squeegee-like concrete smoothers in hand. So, I hung out and watched the project. First, the cement truck backed up, and one of the men took hold of the cement shute and positioned it over the dirt, 4′ x 4′ square. Then, it happened fast.
The cement rolled down the shute and the workmen smoothed it out, while I got to visit with a representative from Ventura County. He told me that rebar would actually be a bad thing for sidewalk support, because, if tree roots started raising the sidewalk, the rebar wouldn’t stop that from happening, and would actually help raise more of the walk. He recommended buying a metal root barrier of approximately 3′ high that one can insert into the dirt between a tree and a sidewalk. Think I will check it out.
Oh, and of course, the mail person came by delivering mail at the same time!
