No pics,,, because there is too much "stuff" in the shed.
I ran the gray PVC (2" IIRC) all under the place.
I put it in for the input power to the electrical panel.
I have PVC for future installations of propane, water, cable TV(LOL!! :laughing

I even put 3/4" PVC in for a possible land line wire,,, who knows,,
my shop is metal (entirely) so cell service is horrible.
Then,,, I ran the same size PVC from where the electrical panel is to 4 other areas of the shed.
My ceiling is mostly 22 feet high, I figured wire under the slab would be neater than overhead.
With short runs of conduit, I have very clean looking electrical installations.
My air compressor is near the electrical panel, I may use one of the PVC's for a remote air outlet.
I also "roughed in" for a full bathroom in one corner,,,
PVC is so cheap,,, put EVERYTHING in that you can dream of,,,
it will look great later.
Oh, yea,, the only thing I didn't do was to install some sort of "man hole" where the PVCs' exit the building.
Each time I up date something,, I gotta hand dig with a shovel instead of a backhoe.
I can not risk damaging the esisting installations, and I can not leave an open hole,,, :confused2:
