Step 1
For a hearty brick wall with trench mortar - filled articulation , the poured concrete footing should be double as broad as the plannedwall width . The thickness of the pour concrete footing should be the same as or greater than the breadth of the planned wall . When built , the wall material should be center on the footing , with an equal amount of blank between the brick and the footing bound in front of and behind the bricks
Footing Depth Considerations
terms deepness is an important consideration , especially in colder climate where the soil freezes . The footing must broaden below the freeze line , the last-place depth at which the ground freeze , so as to avoid frost heave . If the foothold does not penetrate deeply enough , the bulwark will in all likelihood break down or show damage after a few freeze - thaw cycle . In warm areas where stain does not freeze or the frost line is bare inches below the soil surface , the trench for the footing only has to be compass profoundly enough to admit the terms and 1 column inch of rampart stuff for every 8 inch of project above - level wall material .
Step 2
Reinforcement and Drainage Considerations
Taking criterion such as installing brand reinforcement in the ground and continue from the footing up into the wall stuff may increase the strength and effective lifespan of the brick wall . Solid masonry paries with poured concrete footings require that drainage requisite be taken into account . Although weep trap placed throughout the wall will accommodate drain , there must also be a waste pipe tube or drain tiles at the understructure of the footing . The perforated drain pipe or tile should be aim at a slim gradient that allows it to drain to an outlet , and it should be surround by uncouth gravel .
Footings for Dry-Stacked Wall
If the brick wall will be dry - heap rather than mortared , the wall will not want a poured concrete foothold . Without a solid ground , the wall is less vulnerable to frost gag and the ground does not necessitate to extend to the same profundity as a poured concrete footing . To construct a footing for a dry - pile continue bulwark , turn up a trench that is 5 to 7 inches deep plus 1 column inch for every 8 inch of planned wall height . Lay 4 to 6 inch of form crushed rock in the trench and tamp it down , checking for level regularly and making adjustments as needed . Top the crushed rock bed with an in of bedding moxie , and then begin to lie in the first course of bricks .
