Sof’Bounce Conversion Chart

To Calculate the material requirements for your site, please follow the conversion steps below:

STEP 1

Playground Area

(LENGTH) X (WIDTH) = (SQUARE FOOTAGE)

STEP 2

Cubic Feet

(SQUARE FOOTAGE) X (DEPTH) = (CUBIC FEET)

STEP 3

Number of Super Sacks Needed

(CUBIC FEET) / 80 = (NUMBER OF SUPER SACKS)

STEP 4

CALCULATION EXAMPLE

Your playground dimensions are 30 ft. long by 30 ft. wide which equates to 900 total square feet. Your critical fall height is 12 feet. Identify material depth for 12 ft. fall height on the critical fall height chart and add 2 inches for compaction, equaling 8″ of material required. To calculate cubic feet, multiply 900 sq. ft. by the depth conversion for 8″ of material or .666. Depending on how you would like your Sof’Bounce delivered, divide the cubic feet by the super sack formula. In this example, the playground area requires 8 super sacks (2000 lb).
