Since the weight of the water in an oval above ground pool is not evenly distributed, a support system is needed to keep the pool standing upright. There are two types of support systems available:
- Buttress Oval Swimming Pool (A-Brace)
- Buttress Free Oval Swimming Pool (buttress-less)
Buttress Oval Swimming Pool
If you had an oval above ground pool growing up, chances are it was a buttress pool that used A-Braces to support the straight sides. These A-Braces would stick out about 3-4 feet on each side. The fact that you need all this extra space to install the pool means you have to settle for a smaller size pool if you have limited space in your yard. This was one of the drawbacks of this style pool. Kids also have to be careful when playing around the pool to make sure they don’t trip over the buttress. Besides these shortcomings, most people would agree that the appearance of the pool with these A-Braces isn’t very attractive. If you are building a deck around the pool or are installing the pool semi in-ground, the A-Braces will not show, but you will still need that extra space for the buttress oval swimming pool installation.
Buttress Free Oval Swimming Pool
The newer style support system uses pressure plates that attach to beams that run underneath the pool. This is called a buttress free pool. These pools eliminate the need for the large A-Braces which means you can fit a larger pool in a smaller amount of space. Although the buttress free oval swimming pool design does not have A-Braces, it does have gussets that stick out ever so slightly on the straight side of the pool. Unlike the buttress style, instead of taking up 3-4 feet on each side, the swimming pool gussets only need about 1 foot on each side (depending on the model).
It is important to note that if you are going with a buttress free oval swimming pool design, you are not sacrificing functionality for aesthetics. The buttress free style is as safe and sturdy as the buttress A-Brace style pools.
