Drainage on north side of house

Because the surface bedrock we are on is an impermeable chlorite schist, any downpour or spring thaw will run off on top the rock. This means that we should take advantages of natural cleavages and ruts in the bedrock to divert any water away form the foundation footings.

The north side of the house is naturally drained by a crevice that Normand managed to excavate with the bulldozer. I'm glad he did because it allowed us to position the house adjacent to the crevice as opposed to over it! It actually does run under the northeast corner of the house seen in the back of the image. Fortunately, it is not as deep as pictured in the foreground.

To make sure the part of the crevice under the house drains, we placed a drainage tube under the footing (pictured here at bottom). The water line from the well will run through the top tube. The backfill will will be about 3-4 feet here and be covered by a board of Styrofoam SM. That should keep the water from freezing in the wintertime. Hopefully, we'll manage to keep water from entering under the house at all by draining the water into that rut that runs behing the house.
