In some areas of the country the ground is too hard as it is mostly rock or hard clay.
Above ground concrete block swimming pool.
A concrete barrier between the liner and this.
The vast majority of above ground swimming pools are built directly on the ground.
Set stakes at the 4 corners of the dig area cross measure to ensure the dimensions are square.
Like a semi inground pool an above ground concrete pool needs retaining walls to sustain the pressure from the thousands of gallons of water.
Retaining walls can get pricy 7 000 to 20 000 each so that s where most of the added cost comes in.
This is just one method for building a concrete swimming pool.
These areas have to be dug up and or chipped away into a flat area and then sand or limestone is brought in for leveling.
We cut the sides out of the base row of block to let rebar and concrete connect the wall and pool floor.
Stacking the blocks with cores lined up put a rebar vertically every 8 inches.
First establish the size of the swimming pool and the location.
For an 8 block wall pool we want to mark the location 12 larger on all walls.
