What happens here

Learn to differentiate between terraced retaining walls and single, engineered walls. Many landscaping and concrete companies build terraced walls to circumvent engineering requirements, assuming that separating the walls negates the need for professional design. However, terraced walls actually place a greater surcharge (load) from the upper wall onto the lower wall, increasing the risk of failure. The correct approach for significant retaining structures is to build a single, engineered wall, which includes the use of geogrid for reinforcement and obtaining city approval.

Goal: Recognize the structural difference and proper application of terraced versus single retaining walls.

Tools and materials

  • Geogrid — Reinforcing retaining walls, specifically in engineered designs, to improve soil stability and prevent failure

that button. You can do it. Emmy is less than 3 years old and what you see is not uncommon. Unfortunate truth is a lot of landscaping companies and concrete companies build a terrace retaining wall. This wall should have been engineered, built as one unit. So the reason most people will design a terrace retaining wall is cuz they're trying to cheat the system. They think by separating the retaining walls, they don't have to engineer. But nothing could be further from the truth. In fact, when you terrace a retaining wall, you put more of a searchcharge on the lower wall from the upper wall. It's simpler and easier to build a single retaining wall, but you got to get it engineered. You got to put geog grid in it, and you got to get city approval. Most contractors try to avoid those
