I put together a list of projects which I hope to complete before summer. One of those is to bury the gutter drain line which lays across our walkway around the house and across our yard to the hill in front. This is not as simple as grabbing a shovel, since the gutter downspout is above our concrete walkway and I have to get beneath a 6 foot stretch of concrete walkway.
So below shows the story in pictures. Using a concrete blade on the ciruclar saw, I cut the one large concrete piece in half (so each was light enough to move...with help... barely). Then cut a notch for the drain pipe. Then dig, dig, dig. Oh, since I was under there I also dug out an extension of the French drain I ran up to the concrete walk.
Once done digging, I laid new drain pipe out the the edge of the hill. Backfill with gravel and move the ungodly heavy concrete back into place and done!
