Above-ground pools can be placed on concrete. The concrete pad eliminates vegetation from growing under the pool, so weeds will not be a problem. One factor to consider when placing an above-ground pool on concrete is that it must be level or else the pool will be lopsided. For pools on top of grass, sod needs to be removed beneath the pool or else grass may grow through the pool liner, which can cause problems. Some states require a specific amount of sod to be removed beneath and around the pool wall before installation. Overall. it is easier to place an above-ground pool on concrete because it requires less work.
Most above-ground pools are about 4 feet deep, but some manufacturers make them up to 6 feet. A deep end is commonly seen in the oval above-ground pool designs.
Above-ground pool warranties can be voided in a number of ways. If the pool is altered in any way that the manufacturer does not sanction, the warranty is considered voided. Failure to install a pool correctly is a cause for a voided warranty as well. If the pool is left without water in the sun for more than one day it can ruin the liner, which is another reason for voiding the warranty.
