Build on a strong, elevated base
A stem wall foundation starts with a reinforced footing. On top of it we lay a short concrete block wall, grout and reinforce the cells the plans call for, bring the inside up with compacted fill and then pour the slab. The result is a floor that sits above the surrounding ground and a foundation edge that is straight, strong and ready for the walls above.
Stem walls are especially useful when your plans require a higher finished floor elevation, on sloped lots, and for additions that have to match the floor level of the existing house.

Stem Walls: common questions
Why choose a stem wall instead of a monolithic slab?
A stem wall lets the floor sit higher above grade and handles uneven lots better. A monolithic slab is often faster on flat lots where the floor does not need to be raised. Your plans usually decide, and we can walk you through the options.
Can a stem wall match the floor height of my existing house?
Yes. For additions we set the stem wall and the fill so the new slab lines up with your existing floor.
Do you also pour the slab?
Yes. We can build the footing, stem wall, fill and slab as one job.
