Need help estimating concrete

[woodguy]

I want to pour a 2' x 3' slab of concrete to hold the pump, filter,etc for an in ground pool that is being installed in my back yard. How thick do I need it to be and how many bags of 80 lb concrete do you think I will need. My dad has a small motorized mixer, would that be the way to go?

Thanks Woodguy

Sorry, that's all the help I can offer.

4" thick would be sufficient for what you want to do. Calculate the sq/ft and use the calculator listed above to determine the bags required.

Aren't you paying the pool contractor to do this for you?

Yeah, if they're still onsite, and assuming they are gonna pour a concrete apron around the pool, I'd be asking the contractor to take care of it. A 2x3x4" pad isnot going to take much material.

I did about the same size for my pump and filter, can't remember how many bags I used, but I generally throw in some rocks that happen to be laying around to reduce the amount of concrete I have to mix.

I mix 2 80lb bags at a time in my wheelbarrow..... something that small I wouldn't bother with a mixer IMO.

I haven't done the calculations recently but seem to remember an 80# bag makes up about 2/3 cu. ft. of concrete. Figure your cu ft and then you can calculate how many bags. Or use the calculator referenced above as you should be able to pour it 4" thick with no problems.

A pad 2'X3'X4" is .07 cu/yd. It will take 4 80# bags of quickcrete. Personally I'd use the mixer if you have it. It's no harder to wash it out than a wheelbarrow. Hope this is the info you needed.

I guess I would probably go for more of an over kill. I'd dig it out a bit like 4" down, toss in a tad bit of stone and form it up for 4" above ground. This would make it 8 inches thick and maybe less prone to settle and sink to one side.
