Frequently Asked Questions
How thick should a concrete retaining wall be?
For walls up to 4 feet tall, 8 inches is typically sufficient. Taller walls require engineering and may need 12+ inches thickness.
Do I need rebar in a concrete wall?
Yes, most concrete walls require rebar reinforcement. For retaining walls, horizontal and vertical rebar is essential for structural integrity.
