Brick retaining walls protect your property while enhancing its appearance. When a cut is made in a hillside, escaping moisture will eventually erode it into a slope. Retaining walls prevent this erosion by holding moisture in the ground.

This is an ambitious project and calls for particularly good workmanship. Remember to comply with local building codes. This wall is to be built no more than 3 feet high. Study the diagram and refer to it frequently.

Dig excavation as indicated. Use some loose brick to lay the bottom reinforcing bars on. Wire the vertical bar to the bottom bar and prop in place. Insert remaining bars in the top of the footing as the concrete is poured.

The concrete footing should be allowed to season for at least a week. Lay up the brick, using your best workmanship and shoved joints, inserting prefabricated steel joint reinforcement where indicated. Some brick must be cut for the insertion of "weep holes" of plastic tubing 1 inch in diameter every 4 feet along the wall as shown

Before capping the wall with a solid row of brick laid on edge, pour grout in the gap between the brick to bond the reinforcing bars. Grout is mortar to which water has been added until it is thin enough to pour.

When the wall is completed, brush asphalt coating on the earth side to make it watertight. A "French drain" of gravel should be placed behind the wall down to the weep hole.
