Structural Engineering questions, answered by experts

Precast concrete can be reinforced with rebar, wire mesh, or other materials to improve its strength and add stability. Precast concrete for large construction projects is often pre-stressed as well for greater structural strength. Reinforced concrete is durable and strong, making it an ideal choice for many construction projects.

You should pick steel for your new support beam for a few reasons. While steel is more expensive than other materials, such as laminated veneer lumber or glulam, it offers the following benefits:

  • Fire-resistant

  • Unaffected by pests

  • Longer-lasting

  • Stronger against water damage (when galvanized against rust)

The standard thickness for an LVL beam is between 1.75 inches and 7 inches. 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.

Failure to compact the soil during construction is the most common cause of leaning retaining walls. In addition, poor drainage can lead to excessive water pressure behind a retaining wall, pushing against it until it begins to move forward away from the soil it is holding back.

A structural engineer’s report is almost always worth it, as it can help you avoid buying or overpaying for a home with structural issues. The most important thing the report does for you is provide peace of mind that you won’t have to pay thousands of dollars for structural repairs right after closing on a property.
