Excavating and receiving my 12'x24' this weekend. I'm Ready!... I hope

Your on your way - before you know it you will be swimming. BTW, we want PICTURES.

Day 3 UPDATE:

Looks like my optimistic schedule is officially derailed. No sand today. Heck, we haven't even opened the boxes or pre-assembled the center towers yet. What's worse is that I took a vacation day today to get everything in good shape. Looks like I'll take a couple evenings digging and preassembling towers, then this weekend

Long day digging (1:30PM-10PM=8.5hrs, 4+ with DW). We have over 3/4 of the pool area leveled by hand. So far it is really level (within 1/4 inch everywhere I check). The hardpan was really tough going in several spots. We didn't dig too deep with the excavator so we'd have a solid bottom. Good news is it's solid. Bad news is we manually dug out 2-6" of rocky packed soil from several locations. Tough going, but funny enough I found it very rewarding. I think we hauled out about 3 yards of dirt by wheelbarrel (I lost count after about 12 heavily loaded wheelbarrel

My dear wife thinks I'm crazy, but she is patient and willing to help out still. We even got the kids to help dig. I'll try to post that picture sometime (and keep it forever as proof that our kids did help out).

Turns out we dug down 14" at far side of our dig site.

QUESTION: What's the best way to finish the walls that will be 8" to 14" below ground level we have dug out?
Our wall will be 14" below ground level at one side and ~8" down for most the rest of the area. We'll have about 2-6" between wall and the dirt, so I either need to excavate more (which isn't good right next to our existing deck about 18" away) or I need to protect the pool wall from corrosion that would be caused by dirt backfilled right up against the pool wall (after water filled of course).

My current idea is to line the space between outside wall and dirt with weed barrier, then fill the insert with pea gravel to ensure moisture isn't locked against the exterior wall all the time. This will make fine drainage AND it is removable if I find out that this is not a good option. I've read somewhere that applying tar to the wall exterior is good for preventing moisture damage, but I'm not sure what kind or if this really is a good idea.

Oh yeah, did I mention that it was raining yesterday morning and this morning? I've been tarping over half the pool and keeping a 10x10 canopy over the other half. So far that has left the soil workable with only minor mud situations (mainly between pool and the dumping site). Now we just need to figure out what to do with all this extra fill dirt... after the pool is constructed. Focusing on the pool. Must construct pool...

Wups, DW just fell asleep next to me (we just finished watching "Good Eats" popcorn episode on Food Network). I should probably get some sleep too. I'm near performance reviews at work. As long as my fingers are still working tomorrow I should be OK. Most the rest of my body aches but that's fine with me .

Sorry, I have photos but I need to open an account on Flickr, SmugMug (costs money after 14days), or look up other hosting service. I may just host on my Windows Live Space tomorrow . Bed time.

Sounds like you're doing well with the progress.

The biggest screw up in any home built pool project WILL be the timeline for building the pool - I thought my pool would get set up in one weekend, weather got in the way and postponed the job for over a week, in total, I probably spent 3 days at it including levelling and compacting screenings and sand as well as the entire pool build right up to filling.
Electrical and proper plumbing was one more day, finishing the entire area around the pool for no maintenance - 3 years!

Oh I remember well! Yep, we had those kind of setbacks too but alloted enough time (you can see how long it took!) so that we could do some each day without getting too ticked off at setbacks. We even took a vacation in there at the end and when we came back we were refreshed and ready to go at it full force again.

If the pool is going to be in that location forever, then I think Dennis mentioned the tar option for backfilling protection. Who is going to see it if it never gets pulled out except to put a new one in many years down the road? The other option is to dig out further and build a retaining wall which a lot of people do.

BTW, I use Photobucket too. Easy to use, free.

Day 3.5 UPDATE: We are 100% LEVEL!

6/20 7PM-10PM finished off leveling (3hrs)
Hour tally:
~4hrs sod cutting (including rental pickup and dropoff)
~2hrs sod rolling and stacking near pool site
~10hrs excavator + pickup roughing out the hole
~13hrs hand leveling
--------------
~30hrs total excavation
Most work completed within 4 day period!

I have verified all locations around edges and middle are within 1/4" using laser level and tripod.

HAND-LEVELING TECHNIQUE: During leveling I'd confirm level and depth (with laser) for two rows about 10' apart, then lay 2"x2" straight boards in the level rows. Then drag a 10' long 2"x6" board that I made notches in to accomodate the 2"x2" boards. See picture of me digging for a visual example of how this works. High spots raise the leveling board, low spots show a gap.
TIP: Grab some extra dirt and throw it into the low spots, then drag back over with board. Compact the filler you just added. (I wasn't more than about 1" off for my worst fill-in spots. I'm not worried at all about the foundation.)

LESSON #1: Plan how to dig with heavy machinary so you spend less time with shovel and wheelbarrel.
I wish I'd thought it through more before I did the excavating. I worked back to front, but missed some spots and didn't get as close to level as I could have. Experience gained at the expense of sore arms/back and hours of extra manual labor.

We were careful not to disturb below level and we did surprisingly good at getting within ~6" of level with the excavator in many spots.


Hardest part was shaving 1" off an entire section (6'x6') of hardpan that I had leveled but was 1" too high. What a pain.

Best part was doing excavating with the kids helping with the controls. Pictures and priceless memory.


LESSON #2: spade shovel + mattox/pick axe + laser level + 3 level boards + big level are your friends.
I thought square shovel would be helpful. Spade shovel was much better even when shaving 1/2" of loose dirt or hard pan.

Here's some pictures taken during excavation (sorry for the reverse chronological order... it's almost 1AM and I must get some sleep):

Wow, that does look like hard work. You are going to appreciate your pool more than you know once it is done. We used a lot of our farm equipment to move and level - doing it by hand deserves kudos, I don't think I could have done that! How wide is the area you are digging out? Make sure you have enough around the sides cleared as well (appx 2' all around)
