Calculating Concrete Pressures

Concrete pressure compounds with the height of the pour.

• 150# at 1′, 300# at 2′, 450# at 3′, etc.

Formula for wall form pressure

• Sq. Ft. per tie x 150# x height of pour = pressure per tie
• example: 2’x2′ tie pattern equal 4 sq. ft. per ties
• 4sq. ft. x 150 x 6′ height of pour equals 3600#. This is the pressure of the bottom tie of a 6′ lift of concrete with the ties on 2’x2′ tie pattern.
