A 90lbs bag of Sakrete is 2/3 of a cubic foot so 10 yrds(270 cu ft) about
408 bags// 28 days 4200 psi
I had a concrete guy pour 3 yrds for a base of my 50ft universal tower. I
had the hole dug all he did was order the concrete and wheel it to the hole
$400 best money spent, I lost track of how many trips at 40. Its funny at
the start he ask the driver to fill up the wheelbarrow by the end it was
half full.
My other tower(Aluma 75HD) 75ft crankup tilt over, installation was even
less, $100 for a 12inch dia hole 6ft deep. no concrete. It has survived 2
hurricanes major ice storm and an earth quake.
