If a couple bricks have crumbled and fallen loose from a retaining wall that surrounds your property, clean the damaged area and replace the bricks by completing the following steps. After the new bricks are installed, the wall will be stable and will have an attractive appearance.

Gather These Materials

  • tarp
  • wire brush
  • chisel
  • hammer
  • bucket of soapy water
  • scrub brush
  • water hose
  • mortar mix
  • measuring cup
  • mixing stick
  • trowel
  • damp sponge

Remove Damaged Pieces & Clean the Wall

Lay a tarp next to the damaged portion of the wall. Move a wire brush briskly back and forth over the damaged section to assist with removing loose brick pieces and old mortar. If some of the parts of the broken bricks are difficult to remove, place the tip of a chisel against them and tap the tool firmly with a hammer. Continue this process to remove all of the pieces.

Once all of the brick pieces and old mortar have been removed, clean the same area with a scrub brush and soapy water. Rinse the soapy residue from the wall with a water hose and wait for the wall to dry.

Install New Bricks

Read the instructions that are listed on the back of a bag of mortar mix to determine how much water will need to be added to it. Pour the two items into a clean bucket. Stir the mix and water until it is smooth and creamy. Place an even layer of mortar mix on the edge of a trowel. Slide the trowel across the edges of each brick that will be surrounded by other bricks in the wall.

Insert the bricks in the wall, one at a time, and push them firmly into place until they are stable. Use the flat part of a trowel to smooth out the mortar that is in each joint so that it is level with the mortar in the rest of the wall's surface. If any mortar gets onto the front of one of the bricks, wipe it away with a wet sponge. The mortar will need a day or two to dry. The amount of time depends upon the thickness of the product that was added to each brick. While you are waiting for the mortar to dry, prevent the wall from being exposed to moisture.

The retaining wall will add beauty to your property. For more information, contact companies like Mara Restoration, Inc.
