How To Build an Engineered Retaining wall & Avoid Contractors that cut corners
What happens here
For inside 90-degree corners, instead of cutting blocks in half (which weakens the corner), over-build the corner by extending full blocks past the corner, creating an interlocking design. This technique adds significant strength and longevity to the corner. The video demonstrates how to layer the blocks so that each course overlaps and interlocks, forming a robust corner. While this method may use slightly more material, the increase in structural integrity far outweighs the additional cost.
Goal: Build strong and stable inside 90-degree corners for the retaining wall.
