Foundation slope
Foundation slope
(OP)
Are there any guidelines in any of the building code sor elsewhere that give permissable values for slope on a home foundation? Is 0.5% too high (3" over 48 ft).
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: Foundation slope
Is this for an existing individual home or for a specification for future construction?
3" in 48 feet is too much from a practical standpoint. For structural, it would be of little consequence.

1. Human comforts wrt slopping slab.
2. Sliding stability, with the potential to have the slab cracked due to uneven loading conditions not considered in the design, against the horizontal forces on the slopped foundation.
If there is any doubt, and if this is an existing house has sinked after the flood, I suggest jacking and new footing shall be considered.

In New Orleans, we've all lost our marbles. Otherwise we wouldn't still be here.

You might also try looking at ACI 117 specification for tolerances. Obviously the original house designer intended a level slab (that's zero slope), so one could argue the tolerances set forth in the ACI spec.

Unless the slab is moving, I don't think that it should be messed with. Your link seems to support that conclusion.

AA: 1/8" in 10 ft
AX: 3/16" in 10 ft

Anyone know what these classes are?
