Wall Masonry Repair Help Wall Masonry Repair Help

Masonry repair is required on any crack in a brick wall, as a crack will weaken the structure. Generally, they are sturdy structures than can last for a very long time, a prime example being the Great Wall of China. Here are some things to keep in mind when conducting masonry repair.

Crack Stitching Technique

This technique of masonry repair is for any cracks that are 1/2-inch to 1-inch wide. This involves mechanically raking out the first 3 or 4 inches of mortar at the bottom and top of the crack and cleaning it with water to ensure there are no lose bits of mortar. Next, a proprietary non-shrink cement-bonding agent is pumped into the back 2 to 3 inches of the hole. A highly deformed stainless steel crack repair rod is pushed in and mortar fills up the end of the hole so that it matches the rest of the wall.

Mortar Filling

If a crack is less than 1/2-inch in width it can just be filled with mortar. Before filling the crack with mortar it is usually cleaned out, because small bugs and debris can collect in the cracks.

Plaster Repair

Many masonry walls have been covered in plaster to give them a sleeker finish in the modern age. If this begins to crack it needs to be removed and plastered again. When removing it, make sure there is no damage to the masonry wall that needs to be repaired first.
