Repairing Your Home’s Foundation: Loose Blocks or Bricks

The most known cause of a loose block or brick is actually a cracked mortar. This material deteriorates over time and if it’s not repaired properly, it will weaken the integrity of your foundation and the structure itself since other elements can penetrate through it.

Tools Needed for Repair of Foundation

  • Silicone or acrylic masonry sealer
  • Brush
  • Hammer
  • Chisel
  • Mortar: homemade or premixed (1 part of masonry cement to 3 parts of fine sand)

Steps of Foundation Repair

1. Use the cold chisel and the hammer and start to chip away the loose and cracked mortar. Then, you get rid of the present material to an approximately 1/2 of an inch depth.

2. Prepare the mortar by adding sufficient water to form a paste-like solution which shares the same consistency with that of an oatmeal. Then, allow it to set for about 5 minutes before you use it. It’s always best to maintain it in a dry area because if it’s too wet, it will deteriorate or weaken that particular wall – making it more difficult to use.

3. Get rid of the rest of the particles by brushing the areas or corners with fresh water. Actually, this will allow the mixture to set properly and avoids the old mortar from getting all of the moisture from your newly-repaired one.

4. You can now put the mortar with the use of your trowel. Keep in mind to force the mortar first into the vertical joints and remove the excess, as well. This will definitely create a more uniformed and smoother finish.

5. Right after the new mortar has settled, wait for 1 or 2 weeks prior to applying the coat of a high-quality silicone or acrylic masonry sealer, in order to prevent cracks or crevices from expanding during colder temperatures.


Leaks, particularly water leaks, can actually bring an unforeseen hazard which doesn’t only affect the structures of your foundation but also, to your health as well. Moisture that protrudes through the walls can also result in mildew and mold formation which, in the near future, can cause one of the most harmful skin and respiratory-related illnesses and diseases. In order to start repairing these leaks in your foundation, you need to look for crevices or cracks which are showcasing moisture.

Tools Needed

  • Wire brush
  • Plastic sheets
  • Outdoor adhesive
  • Air pump
  • Shovel
  • Epoxy resin or concrete

Using your shovel, dig 30 centimeters around your home’s foundation and shovel the soil against it to form a slope. You should not be afraid to make sharper slopes since the sharper it is, the better. Start laying plastic sheets from your home’s foundation outwards. Then, attach the sheets to your foundation with the use of an outdoor adhesive, then allow it to dry or cure. It is highly advised to put soil with a high-containing clay over the plastic sheets in order to prevent water or moisture from penetrating through your home’s foundation.
