I need to have a concrete slab poured to provide a place to anchor a 330 gallon propane tank so it won't float away in the next flood. I live on a barrier island (Topsail Beach, NC) and we sometimes get flooding associated with hurricanes... not from storm surge but rather from lots and lots of rain.
Anyway, I want a 4' by 10' concrete slab poured 8 inches thick for this tank to be strapped down to. The tank looks like a little submarine.
I've posted an ad on Craiglist and got three replies so far: one is for a turnkey job for $450, one is for $150 but I have to provide all materials, and the third never said but left a phone number for me to call.
Using an online concrete calculator shows this should take 1 yard of poured concrete or 45 bags of 85 lb concrete. I have no idea how much it would cost to get a yard delivered. I've had some limited experience with those bags and am confident that is not the way to go.
No matter how the concrete is mixed, it will have to be moved from the driveway to the back yard using wheelbarrows.
