Retaining Wall Skills: Beginner to Advanced

What happens here

This step demonstrates how to create an outside 45-degree corner. The process involves marking the block using a 12-inch framing square at the 4-mark, then saw-cutting the block along this line to create the 45-degree angle. This ensures that each face of the cut block is identical, providing a clean and consistent look. It's crucial to use saw-cuts for these corners, as splitting would result in a rough, uneven edge, which is aesthetically undesirable and structurally weaker. The speaker shows a past project where improper splitting for a 45-degree corner led to significant gaps and eventual wall failure, highlighting the importance of precise cutting.

Goal: Construct a precise and durable outside 45-degree corner.
