Mixing Flocculants For Concrete Wash Water

Substances such as concrete wash water can be just as corrosive, and if left untreated can cause concrete burns, damage to vegetation and the surrounding ecosystem. Suitable provision should be made for the washing out of concrete mixing plant or readymixed concrete lorries. Such washings cannot flow into any drain or watercourse. Readymixed.
