How to Grout a Foundation

If your home has a foundation of brick or similar building material, you may notice over time that the lines between the bricks are deeper than they used to be. This is normal in the wear and tear of a house, as some of the cement between the bricks crumbles and wears out. If the bricks are moving at all, you need to have a professional look at it for structural issues. Otherwise, you can fill those lines yourself with grout, a form of cement. Using a grout bag will allow you to target the grout specifically into the lines.

  Combine grout powder and water in your bucket, in the ratio specified on the packaging of the grout. Add enough to make about half a gallon of grout. Blend it using your drill and mixing bit, to the consistency of thick mud.

  Let the mixed grout sit for 10 minutes in the bucket. Re-mix it.
- 3
  Open the grout bag and pour the grout into it. Close the bag.
- 4
  Set the tip of the grout bag at one end of the first open space in the foundation. Squeeze the bag with both your hands, expelling grout into the line.
- 5
  Pull the bag back along the line, continuing to squeeze the bag, filling the line with grout. Continue all the way to the end of the line.
- 6
  Run the curved top of a wooden spoon along the lines, smoothing and flattening the grout.
- 7
  Repeat the process for each of the lines in the foundation. Mix more grout as needed for the grout bag. Let it set for 24 hours.
