Wall base depth

Building a small wall for a customer. Area always is damp and customer said they are having settling problems for home foundation. I am thinking a 8" base would suffice and should be more than enough. Any other ideas would be great

Is the house new/newer? Might need to dig down and compact in lifts as you build back up along the foundation

Field stone, roll them in place. Otherwise dig down to virgin ground and buildup from there.

House been there for twenty years. Just having problems with soil. I'll dig till I hit that good red clay then I will start up from there. I like the big stone idea too.

Not so fast.

Before anything is done, you need to correct the water problem.

Could be an underground stream. An if so you need to divert the water

Could be a broken water line.

Could be a roof water issue.

Do not build a wall without first identifying and correcting the water issue.

DO NOT.

Next - base thickness needs to be speced by your engineer. Usually 6-inch depth is fine.

We are running corrugated pipe from the gutter downspouts. Also regrade where was previously but not enough. We are adding additional base for more support for the wall. It is a three course wall and adding more drainage pipe and rocks then we usually do to the bottom

20 years what does the foundation wall look like? People have been doing a lot of water proofing 3 ft of wall and adding a membrane graded to a french drain by us. It directs the water away from the house and gives it somewhere to go.

Don't argue with DVS. He knows what he's talking about. If a house... A while house is shifting and settling. Your dinky wall will be way more seceptable. Fix the water issue. Trench in the down spouts. Fix the pitch of the yard for runnoff.
