Notes:

For structural reinforced concrete applications, please contact us to discuss your requirements or refer to BS 8500 part 1.

Concrete containing any embedded metal should be specified as reinforced. A higher strength or cement content concrete may be required for power float finish or other finish types.

Some soils are potentially aggressive to concrete and it is important to take this into account if there is no professional advisor. The local building control officer may be able to advise whether the local soil contains sulphates and if so, how aggressive it is. We stock different aggregate sizes if required from the usual 20 mm. Please contact us to discuss.
