over digging Excavation probelm

[scotttonofos]

We dug an inground pool. shallow end 3/ 12. Deep end 6 feet. They over dug the and made the shallow end too small.
We would like more shallow end.
What are the best options to achieve this?
what is the acceptable slope transition in a pool (30 feet by 30 feet)

Owner-build or are you using a pool builder?

 

[scotttonofos]

yes. They recommended filling in with concrete. Not sure how that will work unless there are forms and multiple layers of rebar.
Any other options like gravel?

Check this out, is has a section on over digging about 3/4 the way down the page. Basically it says:

• Properly clean out all loose or disturbed materials to competent bearing material

• Fill voids with gunite or other non-compressible material

• Not recommended to compact fill material

The best way to fix it would be to have the excavator or skid steer who dug the pool to dig it to your specifications.

I do not understand how someone overdigs + makes it too small. Did they make the shallow end too deep AND too small.

IF so they can enlarge the shallow area and use the fill to build up the area they over dug.

JUST Be sure that whatever is the base of your pool is compacted.

Most pool builders dump in 3/4 inch gravel into the pool after its dug to smooth out the area, take care of water and drainage issues. They could fill any area that needs to be built up with gravel and compact it with a vibratory compactor.

Are you getting a concrete/ gunite pool or a vinyl liner?

"I do not understand how someone overdigs + makes it too small. Did they make the shallow end too deep AND too small."

What I gather is that it's a 30 x 30 square, and due to over-digging too much of the pool is now considered to be deep, and too little is considered to be shallow. More shallow area is desired.

thank you for your helpful suggestions.
I forwarded them the link to pool engineering. The overdug area will be fill with gunite

 

[dustin2471]

you got it scotttonofos, fill the over dug area with gunite, if you fill with un-compacted dirt you can have cracking and voids, it will cost a little more for the gunite but its definitely worth the extra $$ for not having a future headache!

it will cost a little more for the gunite but its definitely worth the extra $$ for not having a future headache!

If he is using a pool builder and they or their sub over dug it, they should pick up the extra cost of the gunite to make it right.

 

[dustin2471]

absolutely correct! I think I would look at firing the pool builder if he tried to charge me extra for a sub that he hired and messed up.
