Structural Engineering questions, answered by experts

The depth of any foundation style depends on your climate and how deep the frost line is, as building code requires that the footers of a foundation—which are built into a monolithic slab—sit at least a foot below the frost line. At the southern tip of Florida, for example, a monolithic slab foundation would only need to sit 12 inches under the soil at the widest parts. On some parts of the Canadian border, the frost line is 100 inches, which would mean a minimum of 112 inches, which is prohibitively deep for a monolithic slab.

A structural engineer evaluates any structural components, like floors, foundations, walls, and roofs, to ensure they can support the structure. They also consider the soil quality in your area, potentially extreme weather conditions, and proximity to bodies of water and groundwater to ensure your building can withstand any stresses placed on it by the surrounding environment. Structural engineers work on both new and existing buildings.

The National Association of Home Builders requires repair of any foundation crack of more than one quarter of an inch, although local regulations may vary. In general, any visible crack that is growing in size, allowing water through, or that you have just noticed, is a good reason to call a structural engineer. Cracks can be a sign of a sinking foundation, so an inspection is a good idea for your peace of mind.

Absolutely, as it ensures designs are viable and won’t compromise structural integrity.

If you intend to do the majority of the work yourself, you can pay to hire an architect or a structural engineer to ensure your home remains structurally sound. They can help with the planning to make sure everything is up to code and safe for your family. On the other hand, if you’re not sure your home will be completely safe when you’ve completed the project, let a pro do the job.
