For over 80 years the concrete industry has been trying to control and reduce the concrete build-up in mixer delivery trucks as well as develop safe ways of removing the build-up.

To- date, no where in the world , has there been any commercially viable ways of stopping this build-up and it is considered that the problem is getting worse with the addition of the many new additivies to assist with stronger and faster curing concrete.

In 2008 Jonathan Sweet founded Agi-Kleen Pty Ltd in Australia to use a robotic high pressure water system to remove hardened concrete in mixer drums and in 2011 he was joined by Jim Simpson and Michael O’Neill. The company then operated 3 mobile high pressure cleaning units that offered services all around Australia.

The Agi-Kleen service was recoginised by the safety authorities and industry bodies as a major solution to the build-up problem and Agi-Kleen was awarded many safety awards including the SafeWork Australia safety award for 2014. Up to the end of 2016, Agi-Kleen had successfully cleaned over 5500 mixer trucks and taken out over 5,300,000 kgs (11.66 millions lbs) of build-up concrete.

Despite this success, it was difficult to run Agikleen on a commercial basis because it was operating over such huge areas. Knowing that this commericially could be a problem,in 2013 Agikleen directors wanted to solve the problem of mixer concrete build-up by stopping the build-up occurring in the first place

This appeared to be a big undertaking as there was no system in the world that was considered commercial to stop the build-up. Undetered by this, the Agikleen directors believed with their experience in removing hardened concrete using high pressure water and their knowledge of the industry they thought it would take a year to do this. However in reality, it has taken about 4 years to fully develop the DrumBlaster system. DrumBlaster was then formed to prevent the build-up of concrete in mixer drums by washing trucks out properly at the end of each day. After unsuccessfully searching the world for a suitable system, the directors re-engineered an Australian system that was in the early stages of development. Developed off the back of two successful brands, Agi-Kleen and Thoroughclean, DrumBlaster was launched in 2015.

As part of this development, DrumBlaster has been conducting trials in Sydney, Melbourne and Amsterdam (Netherlands) which have all been successful. The trials at Hanson’s Concrete in Preston Sydney were the most extensive and over a 4.5 month period Drumblaster reduced the build-up by 84.4%.

Sales of DrumBlaster have commenced in Australia and due to the success of the trials DrumBlaster has received excellent interest from American and European concrete companies and we are sending DrumBlasters to the USA, UK and the Netherlands.

DrumBlaster is a member of Cement, Concrete and Aggregates Australia and the National Ready Mixed Concrete Association (USA).
