The Stratex Concrete Washout Bag provides a quick and convenient solution to contain all washout waste. The bag is simply placed under the chute or hopper and the slurry is contained in the plastic/polyethylene inner liner in the bag.
The bag has lifting loops which enable the bag to be fork lifted once the concrete is dry or set.
The outer bag is ultra-strong and is tested to a load rating of 2470kg. All bags are fully tested and certified to Australian Standard AS3668-1989.
