Leakage of containment bunds can be an issue and costly to put right. Typical design and construction has sealed joints and expensive water stops. However, if the bund cracks outside these control points then there commonly isn’t enough reinforcing to control them to acceptable levels. Alternatively, heavy top and bottom reinforcing can be used to reduce the number of joints, this is expensive and difficult and time consuming to construct.
