Basement Waterproofing - Intake Pipe In Basement

A 4" hole is drilled through the basement slab in the desired location for the intake (suction) pipe. Our crew then removes (2) 5 gallon buckets worth of soil / rock through the 4" hole creating a cavity under the slab. This helps draw the radon gas to the intake pipe when the system is in place and running. The intake PVC pipe is installed through the slab hole and sealed in place.
