Re: Driveway surcharge on retaining wall

[Subject Prev][Subject Next][Thread Prev][Thread Next]
If it's my drawing, it gets 2'.  How big would a no-heel footing be on a 7' wall? Pretty "big" in the eyes of a residential contractor. You also might well need a key  - I would be amazed if you didn't need a key, to be honest.

Since the drive way has a reasonable chance of having to support a dumpster (for the future remodel or re-roofing next door) or a concrete truck, I'd say keep with the 2'.  Besides, a wall that rotates is a wall that is viewed as "failing" in the eyes of a picky owner.

I am looking at a short, 4 ft to 5 ft retaining wall that is on a property line.  The property line is on the heel side of the wall, therefore there is no heel at the footing.  Also, there will be a driveway on the heel side of the wall in the future.  If I put a 2 ft (highway) surcharge on the heel side of the wall the footing at the will seems to excessively large.  Since the driveway will be to a residence I think the 2 ft of surcharge is excessive, but there may be some short term construction loads that will be larger than passenger vehicles.  I think that a 1 ft surcharge would be fine for the life of the structure.  Anybody out there disagree with using a 1 ft. surcharge?

Thanks,
