Finish TradesQuestion 268 of 700
On a residential site, finish grading around the building should generally slope AWAY from the foundation. A common minimum is a fall of about 6 inches within the first:
a.10 feet
b.2 feet
c.50 feet
d.100 feet
Explanation
Grading around a building should drop about 6 inches within the first 10 feet away from the foundation so surface water drains away rather than pooling against it. Two feet is too short a run for that fall, and 50 or 100 feet describes a far gentler, inadequate slope near the building.
