I'm planning to build a 10×8 shed that will house the pipework and electrical equipment for a new well I recently had drilled. I would like the shed to sit on a concrete slab just for the quality of life it provides. My well contractor suggested that I pour the slab first, leaving 1×1 holes roughly 1' in from the corners where I can run pipework through afterwards.
- Once the slab is finished with the holes, does it compromise the integrity of slab if I were to dig out the dirt between the hole and the edge of the slab to run the pipes?
- How best to fill/pack dirt back in after the pipes are put in place? Should I fill the holes with concrete, or just pack in gravel to be flush with the surface of the slab?

You could use large Schedule 40 PVC as conduit for the pipes. You'd use large radius bends. Will the pipes be PEX or copper? I think soft copper could be fed through a large radius bend and I am sure PEX could be. This would make replacing piping much easier if you ever needed to replace the piping under the slab.
