Page "Adobe" Paragraph 16

When building an adobe structure, the ground should be compressed because the weight of adobe bricks is significantly greater than a frame house, and may cause cracking in the wall.

The footing is dug and compressed once again.

Footing depth depends on the region and its ground frost level.

The footing and stem wall are commonly 24 and 14 inches, much larger than a frame house because of the weight of the walls.

Adobe bricks are laid by course.

Each course is laid the whole length of the wall, overlapping at the corners on a layer of adobe mortar.

Adobe walls usually never rise above two stories because they are load bearing and have low structural strength.

When placing window and door openings, a lintel is placed on top of the opening to support the bricks above.

Within the last courses of brick, bond beams are laid across the top of the bricks to provide a horizontal bearing plate for the roof to distribute the weight more evenly along the wall.

To protect the interior and exterior adobe wall, finishes can be applied, such as mud plaster, whitewash or stucco.

These finishes protect the adobe wall from water damage, but need to be reapplied periodically, or the walls can be finished with other nontraditional plasters providing longer protection.
