There are two parts to all vinyl liner pools, i.e. the walls, the bottom. The walls are nearly always the first 3 1/2' down from the top, and the bottom is the rest of the pool. In other words, everything below the wall, even the vertical part below the wall, is called the "bottom" along with the flat horizontal section.
The walls cannot be dirt. They can be galvanized steel, fiberglass, concrete, or even wood (cypress). The bottom can be dirt, but a mixture of cement/vermiculite is highly recommended. This will help maintain the dimensions of the pool and will not wash away, or erode, as time passes.
A dirt bottom can work in an extremely dry climate which sees no rain or snow on a year round basis. But even then, rodents can cause serious problems when the bottom is dirt.
I recommend fiberglass walls with a cement/vermiculite bottom. -Good luck.

A vinyl pool liner lock is a device used to secure and hold in place the vinyl liner of an above-ground swimming pool. It typically consists of a track or groove that the liner is fitted into, preventing it from shifting or coming loose. This helps maintain the liner's position, ensuring a snug fit and minimizing the risk of leaks or damage. Properly installed, a liner lock enhances the longevity and appearance of the pool.
Very expensive
A hole in the liner is more likely to suck dirt out then let it in.
High concentrations of chlorine can and will destroy a vinyl liner.
Rubber paint is generally not recommended for use on vinyl pool liners, as it may not adhere properly and could damage the liner. Vinyl is designed to be flexible and waterproof, while rubber paint can create a rigid layer that may crack or peel over time. If you need to touch up or repair a vinyl pool liner, it's best to use products specifically designed for vinyl materials. Always check with the manufacturer for the best recommendations for maintaining your pool liner.
No. Replace the liner.

To fix a detached vinyl liner from its spot on an above ground pool, the water will have to be drained from the pool. Then, a marine patch can be placed on the area to re-attach the vinyl to the place where it came apart. Allow this to dry thoroughly before refilling the pool.
