Oval pool inground with deep end

This was today’s big adventure. It is a 12' x 24' Doughboy pool in the ground with a deep end. The hole for the pool was dug before we started. We had to build the pool and dig the deep end. A 12' wide oval does not allow for a very wide deep area but it is an extra 2' of water, just right for tall people. The final shot shows the completed pool without a hint of wrinkle in the liner.

Nice work Dennis, love the smooth wrinkle free liner, was that liner made special or is it your typical overlap liner?

Nice work.
Really looks like a pro did it.
Did you put sand coves in there?

Thanks Matt, This was a 25 mil Doughboy expandable overlap liner. The 20 mil expandable goes in just as nice. When it comes to expandable, Doughboy truly does have a superior product. These liners can be installed flat bottom as easily as expanded. That means the liners are not oversized, they expand up to 2’6” to fill a deep area of just about any size. That is a big part of the magic to a wrinkle free deep end installation.

Hoffmans, thanks. Yes, the sand goes up the wall a good 6".

Sweet - expandable, hmm, I can see a 10' deep center on mine when the liner needs replacing......

Wonder if they can make an expandable rectangular for a FantaSea--my liner was installed by an evoluntionary throw-back, so it has footprints and wrinkles...The first liner was MUCH nicer but it split a seam and this one was installed by the liner company's choice.

Hey, Dennis--where are you located again??:D

Dennis does that buttressfree model have straps that run underneath? Tell me about how the straps are modified when doing a deep end. Our instructions for our pool show how to put in a deep end but our water table is so high that we thought there would be problems if we dug down. maybe if we have to replace the liner later, we would go that route.....

NWMNMom, Most of the Doughboy ovals are expandable option. Meaning there are no straps. They use an L bracket on the bottom side of the side brace channel that backs up to an 8” x 8” x 16” block. The block is placed under the brace channel, up against the bracket. It’s a fun pool to build. Each side brace is set totally independent of the other braces. They are not connected by pressure plates or straps. It is all done with strings, a tape measure and laser level. Each brace goes through about a five or six point check before it can be backfilled and packed into place.

The Doughboy system has taught me that all oval pools can be converted to deep end pools. If you eliminate a bottom strap you just need to add an L bracket under the brace channel backed up against a very large block.

The straps prevent the pool sides from pushing out. A strapless design uses the downward pressure of the water on the pressure plates to hold a steel channel and bracket firmly positioned on a block that cannot move outward.

I have converted all kinds of pools, I am always amazed that it really does work. With enough weight down and a firm stopper under the brace it is all good.

Anyways, thanks all for the kind words. Anyone truly wanting to convert to an expandable pool please talk to me, one on one, before you do it.

P.S. Carl, I'll give yours a little thought and get back with ya.
