I have my laundry room in the backyard and there is an area that had a thin piece of concrete and below it there is soil. Beneath the soil there lies the drainage PVC 1 ½” pipe, gas line (not currently connected to anything), and water line for the washing machine. I had to dig out the soil a bit and replace a section of en exposed PVC pipe that was broken. The PVC pipe is the thin type. I replaced the damaged section with Schedule 40.
I want to cover up the soil with cement to flush the floor. This will need about 4 inches of concrete (Height) in an area of about 8 inches by 10 feet.
I was thinking of using a concrete mix. I live in an all year warm climate, BTW.
Is it ok to pour the concrete over the compacted soil and not worry that the weight will crush the PVC pipe?
