The more preparation you can do preceding concrete placement pays huge dividends in job efficiency, accuracy, and profitability. We highly recommend the following items be completed before placing concrete:
- Horizontal wood strapping is required on both the inside and outside of the wall when
- The offset between joints is less than 8 inches between rows.
- There is more than 8” between webs.
- Vertical joints are directly on top of each other.
- Window or door openings occur less than 4’ (1.220 m) from a corner. (Run strapping across opening to corner).
- Temporary wood straps are required around window and door openings to maintain straightness.
- Cross bracing with 2x4 supports is required inside window and door bucks to hold bucks in place and prevent sagging or bowing from concrete pressure.
- Foam adhesive can be used on wood and plastic bucks to provide additional buck support.
- All outside corners should be reinforced with tape or wood strapping, and zip ties.
- The top course should be secured with adhesive foam, zip ties, and/or horizontal and vertical hooks. Sloped walls should be properly foamed and braced.
- Radius walls should be secured with foam adhesive and flexible strapping material.
- Forms in all lintels should be secured end-to-end with zip ties.
- The middle of large openings should be vertically braced to prevent tipping.
- All forms should be firmly seated to prevent settling.
