Q: Is a structural engineer the same as a foundation engineer?

• <div><p>Structural engineers specialize in all aspects of a building&rsquo;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 <a href="https://www.angi.com/articles/who-do-i-hire-foundation-repair.htm">who to hire for foundation repair</a>.</p></div>

Q: How much weight does a 4-inch concrete slab support?

• <div><p>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&rsquo;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.</p></div>

Q: What is considered a structural issue in a house?

• <div><p>Any issue that affects the structural integrity or soundness of a home is considered a structural issue. In addition to foundation cracks, other signs of structural issues include roof leaks, bowing walls, sloping floors, gaps around windows and doors, and more.</p></div>

Q: Do structural engineers draw house plans?

• <div><p>Structural engineers draw structural plans, which include detailed drawings of the structural components of a home only. Complete house plans will require additional work from an architect or draftsperson, whose drawings will take the structural drawings into account. They&rsquo;ll also include more details about the finishing materials and layout of a home, including everything from roofing and flooring materials to the position of furniture, light fixtures, switches, and plumbing fixtures.</p></div>
