Retaining walls around Southfield are mostly short, but wet clay and frost push on them every spring. Footings below frost and drainage behind the wall decide whether it stays straight. We look at the soil, the water and the height before we quote.
Southfield is mostly gentle ground, so retaining walls here tend to be short: walls along a sloped driveway, beside a walkout basement, around a patio cut into a grade, or along the Rouge River lowlands. Short does not mean easy. Wet clay is heavy, and when it freezes behind a wall it pushes hard every winter. Most walls that lean were built without drainage, so water and frost had nowhere to go but against the wall.
Every concrete wall we build has a footing set below frost, drainage stone behind it and a perforated drain pipe at the base that carries water away. Steel ties the wall to the footing. For walls that hold up a driveway, a building or a deep cut, we recommend an engineer's design, and we check with the city whether a permit is needed for the height and location.
If you have a wall that is leaning or cracked, we look at the drainage first. A small lean on a wall that is otherwise sound can sometimes be stopped by adding drainage and lowering the soil behind it. A wall that has moved a lot, cracked through or slid on its footing should be rebuilt.
Retaining walls in Southfield: common questions
Why is my retaining wall leaning after the spring thaw?
Usually because water and frost in the clay behind it have nowhere to drain. Saturated clay is heavy and pushes the wall, and freezing adds more pressure. Keep people and cars away from a wall that is moving and have it looked at.
Does a retaining wall need a permit in Southfield?
It depends on the height and what the wall supports. We could not confirm Southfield's exact threshold from an official page, so we check with the Building Department for your wall before we build.
Do short garden walls need drainage too?
Yes. Even a short wall in clay needs drainage stone and a way for water to get out, or frost will push it over time. Drainage is a small part of the cost and the main reason walls stay straight.
