Working with concrete

If in doubt – Stop and Shout! Take the time to plan and use the right system and ensure the wash water/waste is contained and/or removed correctly.
  • Concrete waste water is toxic. If it reaches streams and waterways, it will kill fish and plant life. Dilution is not an option. It would take 1 million litres of water to dilute 1 litre of alkaline wastewater back to a PH of 6-7.
  • Check the weather. When possible choose a dry day.
