Structural Engineering questions, answered by experts

Through proper drainage solutions and compacting the foundation soil.

You should avoid drilling or cutting into load-bearing beams because removing material will weaken it and increase the risk of structural damage or even collapse. If you do need to drill into a load-bearing beam, speak with a structural engineer first to discuss where it’s safest to drill and the width and depth of the bit that’s safe to use.

Yes. Foundation walls are always load-bearing.

Structural engineers specialize in all aspects of a building’s structural integrity, including the foundation. Foundation engineering is a critical part of structural engineering, so structural engineers are experts in foundation design. Many foundation repair companies either have a structural engineer on staff or one they work closely with, so be sure you look for that when deciding who to hire for foundation repair.

No, beams are the primary load-bearers for flooring or roofing systems, and they distribute the weight of the structure to your foundational supports, while joists bear far less weight and distribute their loads to the beams. Beams are usually thicker and longer, and they have support posts or foundation walls beneath them for support.
