I think you meant concrete pad not cement. A 6 in pad should work for you.
The question is, how high was it supposed to be? It should be a minimum of 8", and as long as the ground slopes away from the foundation, there shouldn't be a problem.
If it is at the surface of the foundation, chip away enough of the cement to expose enough of the pipe to work with. An inch or so. If it is somewhere else in or under the foundation, you bust out the foundation and repair it or run a new line above the floor.
there are aluminum pools, steel pools if they are above ground and they also have cement in ground pools that they build in your yard.
I used a sand base for our 20' round above ground pool. It's much easier to deal with after the pool is gone. Greener too.
In order for a person to build their own above ground pool without a kit, they need to make the ground level. They may also want to put gravel underneath the foundation for the pool.
The answer would be entirely dependent on the type of pool (above ground, below ground) and the material it is built from (cement, fiberglass, etc.) and the type of defect (crack, chip, hole, stains, rust, growth, etc.)
The top of a foundation at grade. Foundation walls should be a minimum of 8 inches ABOVE grade.
The forks should be 1 foot above ground
According to Building Control Regulations, the DPC should be a minimum of 150mm above external finished ground level.
A house is built from the ground up. It starts with a good foundation. This can be either a solid concrete slab or pilings for a house above ground. Then you add walls and a roof.
The buoyed weight of the casing above the cement top.
It stands at 30 cm above ground to prevent water from splashing into it from the ground.
