Designer Pre Mix is the only concrete supply company that is environmentally focused and offers an exposed aggregate clean and capture system.  Traditionally in exposed aggregate, the process to expose the aggregate in the concrete involves high pressure cleaning the top layer of the concrete that has had a surface retarder sprayed onto the surface.  Unfortunately, the wash off from the concrete can flow down drains, gutters, pits and pipes possibly causing blockages and polluting our waterways if correct drain protective procedures are not in place.

Our unique clean and capture system eliminates the need for high pressure cleaning.  The unit removes the top layer of chemically retarded concrete, exposing a perfectly finished exposed aggregate without the mess.  This system can be of particular benefit when exposing concrete in small areas, basement car parks, driveways or indoors. Please contact Designer Pre Mix for advice and pricing.

"Dear Brad, Just a brief note of appreciation to let you know that the advice that you gave us on colour selection and type of stone to use to match our existing brickwork and landscaping was spot on which, as you know was in complete contrast as to what my wife and I had originally chosen. The completed job looks fantastic and we could not be happier with the final product."
