The Husqvarna CG200 Concrete Scarifier
Scarifying, sometimes known as scabbling, is an important process for many concrete surfaces. A scarifier such as the Husqvarna CG200 can reduce the surface of concrete much faster than a grinding machine can. The surface it leaves behind is rough, but that can be an advantage in some circumstances. It provides an anti-slip floor, especially useful in agricultural buildings such as cow sheds or milking parlours. A scarified floor will also give extra traction and stability to heavy machinery.
Instead of chains or flails, the Husqvarna CG200 uses multi-tipped cutting wheels. Held on drums, they can be changed easily so the correct profile can be achieved. There is also the option of using a wire brush drum which provides aggressive deep cleaning between floor gaps. The wheels can either be spaced on the drums, or placed side by side. positioning the wheels closer together, the resulting finish will be smoother. Spacing the wheels will create a ridged finish.
As well as concrete removal and scabbling, the CG200 is capable of removing material such as tile mastics and epoxy. Misaligned concrete joints or unevenly placed surfaces can be reduced and levelled. The operator propels the machine forward by hand, giving control over the speed of the removal. It has a rear vacuum port for disposal of waste materials. A medium sized H-Class vacuum such as the Husqvarna T4000 is suggested for use with this machine, but a determination should be made based on the specific use.
The Husqvarna CG200 is of use in some concrete polishing projects, where the level of the floor needs to be significantly reduced. While the rough surface it leaves behind will require grinding to flatten properly, it can save contractors a huge amount of time when it is needed. Misaligned floors, even those with just a few millimetres of difference, can be a significant trip hazard. It is worth putting in the extra time to prevent the risks such a floor can pose.
