Deep End With Keystone Pool

by Tim Steel
(Dry Ridge KY)

We purchased a 33x18 Swim and Play Keystone pool with an expandable liner. We got all excavation done.

My question is, it has the buttress style angle supports, with the strap running from angle to angle, no solid bottom support on angle, my father in law has the same pool with deep end and had it installed and can't remember what they did with the supports in deep area, have seen the way they do it on the Doughboy type supports but don't have a clue on this type of support?

He said they buried something that looked like an oversized top rail and bolted the back of the angles to it, but he did not see anything else they did. If that's the case wouldn't the bottom of the support push out with just that thin strap in between the support and the angle? If that's all they did, his has held for 3 years now, any help would be great. Thanks Tim



Hi Tim. This page

Above Ground Pool Directions

shows a diagram for converting a strap pool to an expandable liner pool. It is simply a matter of duplicating the Doughboy method. You cut the straps off, you add a sturdy L bracket to the underside of the brace channel and you install a couple of 8 x 8 x 16 inch blocks under and behind the brace assembly. That's really all there is to it, that and be sure you use the pressure plates on the inside of the pool.

The block behind the brace and the block behind the L bracket keep the assembly from pushing out. The combination of the block behind the L bracket and the pressure plates on the inside of the pool keep the tops of the braces from pushing out.

The pressure plates take the weight of the water and spread it out across the fronts of the channels, preventing the braces from pushing out at the top.
