The foundation is the strength of your home. A weak foundation will greatly shorten the life of any structure. Water is one of the greatest threats to the foundation of your home. A leak in your foundation will erode the structure, invade the interior of your home, promote mold growth and eventually destroy your home. Repairing a leaking foundation takes a lot of time, even more effort and a bit of know-how.
Mix the powdered concrete patch and water in your bucket. Combine the ingredients thoroughly with your putty knife. Mix only 2 cups of the concrete at a time with enough water to give the combination the consistency of toothpaste. Apply the concrete to any visible holes and cracks in the wall. Press the mix into the damaged areas to fill the voids completely. Scrape excess mix from the wall.
Contact your local utility location service and allow them time to do their job before continuing. Dig around the perimeter of your house with a shovel. Be wary of the marks made by the utility marking company. Do not dig with a shovel within 6 inches of a mark. Dig up to that point on both sides of the mark and dig the remainder out by hand until you locate the line. Dig down to expose the entire foundation. Continue digging 6 inches below the base of the foundation.
Shovel 2 inches of gravel into your trench. Lay the French drain with the slotted side up onto the gravel as close to the foundation as possible. Fill in around the French drain with gravel to hold the plastic in place. Cover the French drain with 2 inches of gravel.
Apply the asphalt-based foundation sealer with your paint roller. Open the bucket of sealer, dip your roller into the tar and roll a thick coat onto the entire foundation. Shovel the original dirt into the trench. Pile up all of the original dirt from the excavation on top of the trench. Walk over the dirt to compact it into the hole.
