How do you repair cracks in an adobe wall?
In repairing adobe cracks, a procedure similar to repointing masonry joints may be used. It is necessary to rake out the cracks to a depth of 2 or 3 times the width of a mortal joint to obtain a good "key" (mechanical bond) of the mortar to the adobe bricks. The bricks should be sprayed lightly with water to increase the cohesive bond.

Are adobe bricks strong?

Mud bricks made from soil containing clay will have a natural waterproof quality that also controls and combats humidity.
Can adobe bricks be fired?
Lots of energy is needed to fire the bricks. The Mexican technique is to stack the adobes to be fired and then build a mortarless vault of adobe over them. A flatbed truckload of firewood is ignited at one end and a simple chimney at the other end gets the fire roaring through the adobes for perhaps three days.
Do adobe houses burn?

Because of this, most of the walls receive the brunt of the weather and are susceptible to damage by the elements; most notably, rain and wind. Compared to a concrete or slump block, adobes are soft, making them prone to deterioration. Few homes can match the beauty of a well-built adobe or rammed earth home.
