Q: How thick are LVL beams?

• <div><p>The standard thickness for an LVL beam is between <b>1.75 inches and 7 inches</b>. However, you can order LVL beams in non-standard sizes as well. When you work with a contractor, they can source beams that are the appropriate size for your project for you after assessing your blueprints.</p></div>

Q: Can I do my own structural calculations?

• <div><p>No, it&rsquo;s not legal for unlicensed individuals to conduct structural calculations for buildings or building repairs. Not only do licensing requirements prevent DIYers from tackling this project, but mistakes can also be extremely dangerous and put your property and anyone inside or near it at risk of severe injury or even death. You should always hire a licensed and certified local structural engineer to make structural calculations.</p></div>

Q: How can you tell if a crack is structural?

• <div><p>Foundation cracks that are 1/8 inch wide or less, aren&rsquo;t uneven across the gap, and don&rsquo;t continue widening over time are usually just normal settling cracks and don&rsquo;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.</p></div>

Q: How much weight can 6 inches of concrete hold?

• <div><p>On average, 6 inches of concrete can hold around 150 pounds per square foot, but the exact weight that 6 inches of concrete can hold depends on factors such as the type of concrete, the reinforcement method, soil conditions below, and structural design. If you&rsquo;re concerned about the longevity of your concrete patio, walkway, or driveway, hire a professional to help you choose an appropriate concrete thickness and reinforcement method for your needs. </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>

He made informed suggestions when we didn't quite know what to choose and he walked us through every selection and procedure. He was skilled, professional and a genuinely nice guy. The end result was better than I ever could have imagined. He will now forever be our go-to guy for our future projects.
