Can you tell me a little more about that floor drain? I assume that it has metal grates/ is safe to drive over? I am puzzling through how to solve a drainage issue that my current carport has (water runs across the floor in heavy rains) before closing it in as a garage. I'd have to rent a concrete saw, but I think I could manage to install that once I got it cut. On the other hand, the whole slab may come out, so... I'd just be diverting rainwater, and the output would drain to daylight on the other (downhill, slightly) side of the roof.
How's it sold? I assume in some kind of 4' or 8' sections? If you don't mind, what do those run each?
