We are seeing, especially in new construction, that the downspout ends about 6" from the foundation. This is a problem because when they excavate for a cellar hole, they excavate about 6' to 8' larger than they need because guys have to get in there and work.
They fill that soil back in, but they don't compact it. When the soil is not compacted, the water can peculate through it. This means that the water can saturate it, then freeze and cause lateral pressure which will push against the foundation and can cause cracking.
You want the downspouts and the soil to be pointing away from the house. That 6'-10' area is known as the "zone of failure" because that soil often alows the water to peculate through, it "fails" to have the water run away.
We recommend that homeowners move the downspouts to about 6' to 10' away from the house. You also want to be sure that your gutters and downspouts are free of debris so that water can easily flow.
