Very old thread that was revived by a spammer, but a new problem has been introduced by a member, so I moved the thread to H&G instead of OT.

Say if I wanted to level an 18x18' square piece of land in order to place an above ground pool on, what would be the easiest way to go about it?

I dont know what they are called but the have a engine on them and a very heavy like metal sled. It will vibrate the piss out of you. Make you hole and you use that machine to pound the ground till it is level using just a leveler.

So you dig you hole or spot and go to town with that thing. We used it on the rail road when installing new gate houses fo rthe had to be perfectly level and of course I was the one to man handle the beast. If you a small person your in for alot of fun :D

The only problem with that is that it's 18' and I don't have a level that big. So one part might be level but the other may not be. I want to know how I can tell if the whole thing is level, not just one part of it.

Maybe if I put a board across the whole thing then level the board?

Pick and shovel, or if you're lazy a bobcat will do the job just fine. Don't take the soil of the high part and put it in the low part, it will settle over the next year or two and your pool will fail. If yout wondering how to make sure it's level, a laser is the easy way. If you don't have a laser, get twenty feet of clear tube and fill it with water, leave a couple feet of air at the end. Then just hang the ends on stakes and measure down from the water. DON'T cap either end of the tube.

Edit: You can also buy a water level at homedepot for twenty bucks. They come with 50 feet of hose.
Here is one.

do you need to raise or lower the grade to a specific elevation, or just get it all level?
If it is close, a couple of yards of sand make the best grading agent. If you don't have easy access to a grade laser or water level, a 10' 2x4 or 2x6 that appears straight will do as the grade checker.

Drive a wooden stake in the middle of the area down till the top of it is the grade you desire, set the end of the board on it with a carpenter's level on top. Adjust the other end and all along it with sand to make the bubble perfectly level. Rotate around that stake and repeat.

Just do it by sections and buy a big level. There really is no easy way about it if it has to be perfectly level. But since it is a pool dont you really just have to level out the sand?? do a 6 foot section and check if it is level and do the same. If you go to low you just throw dirt where your working. Unless you just buy a big escavator I dont knwo any other way of doing it myself. Thats just what we used but I think for a pool you get it the dirt kinda level and then put the sand down and level it. Level dirts not going to do crap for you once you put the sand down.

If you don't want to invest in a water level, just dig a small trench around the outside and fill it with water, it will be perfect.

I've put up many AG pools. The most important tool is a String level

You can pick one up at Lowes/Home Depot or a local hardware store for just a few dollars.

You drive a stake in the middle of where the pool will be and tie a string to it at 5" above the ground and attach the string level. Stretch the string out 9-10' (for an 18' round) and walk a circle around the center stake, placing stakes every 3-4'. At each stake level the string and mark each stake and measure the distance to the ground.

This will show you in which areas the ground is high or low. Depending on the topsoil and the amounts of ground that needs to be removed, you may be able to level it with a shovel and a rake. If more ground has to be removed you may need a tiller to help breakup the ground on the high side and move it to the low side. In extreme cases (on a sharp hill) you may even have to employ a tractor with a box blade, or even a bulldozer for large pools on severe grades

You can't just use a plate vibrator. I just put in a 14 x 18 above ground pool in-ground by digging a big ass hole 4' deep.

My 14 x 18 pool is roughly 7000 gallons or about 280.9 lbs sq/ft A typical playe compactor weighs about 300 lbs on a 17" x 24" plate, or roughly 106 lbs per sq/ft. The water is roughly twice as heavy as the compactor.

'Undisturbed earth' in this area (illinois) will support well over 1000 lbs sq/ft. To put in the pool, you just dig until the ground is flat. That's it. Using a plate compactor doesn't do a whole heck of a lot. All it would do is push any rocks on the surface down since the weight of the compactor will be almost entirely on the rock. But you are supposed to remove them beforehand.

Besides, you are supposed to put between 2 to 4 inches of sand down along with a 4-8" cove around the edges to prevent washout. The sand is the most impotant thing to get level.

To make sure it is level, use a waterlevel as Greenman suggested. a string level will tend to compensate and be self leveling. You could be off by an inch over 20 feet and the level would still read as being 'level'. I used a 6' level first as funboy42 said, but I still ended up with a deviation of about 1/2" depensing on which direction I leveled from. the pool had to be within 1/8" or the wall would come out of the bottom.

String level is the cheapest way to do it. I put in a slightly smaller AG pool 4 yrs ago. Set your stakes, and using the level, set your grade line, then work from that. If you have to move a LOT of dirt, then equipment is much easier on the back, even for a relatively small piece like this.

So how would ya'll go about doing this over an existing lawn? I have been putting up one of those 15' Quick Set type pools in my backyard the last 3 summers and it work OK even though the ground is probably uneven 12"-20" over that distance. I would love to level the ground out somehow and put up a bigger (18' x 48") but don't want to dig up my whole yard (sod) to do so. Any ideas?

I dealt with one of those pools for three years in a row. The last year it finally spilled over because the ground wasn't level. You're really not supposed to "build up" to make it level. What you put under might eventually work it's way out from under the pool.

I gave up and got a used above ground pool for $600 and put it myself. Much easier to take care of and tons less worry. I had to dig the yard to make a level spot, but it's always there now and if I get tired of it, away it goes.

I put in a pool last year and had to level the ground. This thing is cheap and it works well. My pool is level the whole way across by an 1/8".

I have a bunch of questions for those who have done this:

1) Did you do it over an existing grass lawn?
2) Did you dig up sod on the high sod, get rid of the sod or just use it to build up the low side?
3) Did you haul in a bunch of dirt and/or sand and just dump it down?
4) How did you transition the level spot into the remainder of your lawn, just taper it down or use some sort of retaining wall?

Anybody care to post some pics of their leveled section of yard?

Thanks!

I removed all the sod where I put the pool. It will die under there anyway. then, I leveled the piece of ground to within a 1/4" in all directions. (not bad for a string level) Where I had to build it up to get it level, I used the interlocking landscape blocks you can get at Home Depot to provide a retaing wall to contain the soil. (only about 6" higher than the surrounding area.. Once the dirt was leveled, I put down about 1" of fine sand, covered it with a heavy contractor-grade landscape cloth, then covered that with the tarp that came with the Doughboy pool...

I've installed a few, and dug for several in-ground shotcrete pools and large hot tubs.

1.) remove all the sod.
2.) See above, get rid of it.
3.) If the fill is deeper than 6", use 3/4" or 7/8" crushed rock (CSTC is one term for it), to get the grade close. Rent a plate compactor for the day and put it in in 6" lifts.
4.) If it is just a few inches of difference, you can use water to compact good clean sand.
5.) It really depends on the conditions. As somebody said above, if it is a big fill it can and will displace out from under the pool eventually, if it is not retained in some way.
