I had thought of that but do not have any metal working tools or welder (yet). I just moved to the country after 10 years in the city (Chicago) and another 10 in suburbia. So I never had the use for them.
I have concrete (parking pad), asphalt (250'x16'), and Gravel (950' x 2 drives) so I was hopping to use something that would work on all surfaces. The PVC worked well just did not hold up.
I use a rubber squeegee edge on the concrete & asphalt & it works extremely well. The one gravel drive (our main drive) was improperly installed by the previous owner & is pumping and sinking with some areas pretty thin. So I wanted to minimize any plowing impact to the drive until I can get it stabilized. I am thinking of using the black drain pipe (seems to be more elastic) and taking it slower. I can cut & slit the plastic with wood working tools so that is why I'll try this option.
Thanks
