Structural Engineering questions, answered by experts

Yes, a one-story house can have a load-bearing wall. The load-bearing walls in a single-story home are usually the exterior walls. If the house has a basement with exposed walls, the arrangement of the beams can help indicate what walls are load-bearing.

Yes, you can build over a stump if the roots are no longer alive. Living roots will continue to grow and may damage your new construction over time. Similarly, you should also remove rotting stumps because they may continue to attract pests and even cause new structures (especially those made from wood) to decompose as well.

A 4-inch-thick concrete slab can support around 4,000 pounds per square foot if a contractor reinforces the slab with rebar, while that same slab without reinforcements will support closer to 1,000 pounds. For the purposes of a patio, 4 inches in thickness without reinforcement should suffice unless you’re installing heavy kitchen equipment or a hot tub on it. In those cases, reinforcing your slab and sticking with 4 inches of thickness should provide plenty of strength.

Foundation cracks that are 1/8 inch wide or less, aren’t uneven across the gap, and don’t continue widening over time are usually just normal settling cracks and don’t suggest structural issues. Horizontal cracks and stair-step cracks on foundation walls, any cracks that continue widening, are wider than 1/8 inch, or where one side juts out beyond the other, are often indicative of structural damage.

A split-level home is one that has several staggered floors connected by short staircases, while a split floor plan separates the primary bedroom from the rest of the bedrooms. Split floor plans are most often found in single-story homes, while split-level homes are always at least two stories.
