Concrete Retaining Walls FAQs
Do retaining walls need plans?
Walls above a certain height usually need approved plans and an engineer. Check with your municipality.
Why do retaining walls fail?
Often because of poor drainage behind the wall. Water pressure is a common cause.
Concrete or block retaining wall?
Both can work. Cast concrete suits higher or loaded walls, block walls suit lower walls.
How much does a retaining wall cost?
Roughly R1,800 to R3,800 per m² for reinforced block and R3,500 to R7,500 per m² for cast concrete, excluding VAT.
