How to Build a Concrete Block Wall
Step 1: Concrete Block Wall Footing
All concrete block walls—both structural and non-structural—require a solid, poured concrete footing. QUIKRETE 5000 is the recommended product for footing construction, due to its high cured strength and rapid strength gain.
Poured concrete footings should be at least twice the width of the concrete blocks used. Standard 8” x 8” x 16” blocks would require a 16” wide footing. Make sure the footing depth extends below the frost line, and check local building codes for construction requirements in your area.
Tie rods should be set a minimum of 6” into the concrete footing for load bearing concrete block walls. Rebar should be placed in every other masonry core to provide structural support.
For masonry cores over 4” wide, pour QUIKRETE Core Fill Grout Course around the rebar. Use QUIKRETE Core Fill Grout Fine for masonry cores that are less than 4” wide.
