Retaining Walls
Getting to the wall is often the hard part. A narrow side yard in south city, a steep drive in Jefferson County, mature oaks close to the work in Wildwood, a fence line in an O'Fallon subdivision. Any of these changes what equipment fits and how much the job costs. We handle the cut, fill, haul-off and access work a wall needs, and we price it at the estimate instead of finding it out on day one. Before any digging, we have utilities marked through Missouri 811.
On a lot of St. Louis jobs, the hard part is getting equipment to the wall, not building it. In the city that might mean a gangway between two brick houses or an alley with a garage at the end. Out west in Wildwood it's a steep, wooded drive, and in Jefferson County a lot too steep for anything with tracks. In the subdivisions it's usually a fence line and a neighbor's yard. Access decides what equipment we can use and what the job costs, so we look at it first.
Where a machine won't fit, we use a smaller one, lay down a protected temporary route, or bring material in by hand. Each of those gets priced at the estimate.
Wall projects mean moving dirt: excavating for the base and geogrid zone, cutting back a slope, bringing in fill to flatten a terrace, and hauling off spoil that won't go back in. Loess is easy to dig but a mess when it's wet, so we schedule around the weather and protect lawns, drives and the route in. Rocky Jefferson County and Wildwood soils are harder digging and sometimes mean breaking rock for the base.
Before any digging, utilities get marked through Missouri 811. That's free, and it's the law. This work usually goes with new walls, drainage and boulder placement.
We regularly work alleys and gangways in the city, wooded drives in Wildwood, steep lots in Arnold, fenced yards in O'Fallon and Ballwin, and narrow side yards in Webster Groves.
Typical timeline Priced per site. Access matters more than anything else.
Work that usually goes with this one on a St. Louis job:
New walls to flatten a sloped yard, hold a patio or pool deck, or widen a driveway. Drainage and base priced with the wall.
