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.

TYPE OF APPLICATION:
Joint free liquid tight slab

2012:
North Island, New Zealand

This project required a joint free watertight slab to support tanks containing water and fertilizer. This required a crack width calculation of 0.2mm.

SA Water engaged SMEC Engineering to design a 400m long flood channel to cope with a high water flow of 20m/sec. A channel of this size poses numerous detailing and construction issues, however the adoption of the Dramix Combi Slab solution ensured simplification of the traditional steel, removal of water stop joints, allowed for a quicker construction programme and met the required crack width requirement of 0.2mm.
