For nearly 50 years, scarifying and shot blasting machines have looked and functioned the same. For those who still believe that these methods are the smartest way of machining a floor, it's time to think again. The development of HTC's machines and tools means that there is no longer any reason at all for continuing to use old-fashioned methods and equipment.



+ Functions on all surfaces

+ Many areas of use

+ A flat surface can always be achieved

+ Close to edges

+ Low noise level and little dust


Scarifying / Shot blasting

- Impossible to get a flat surface. Grinding or

self-levelling compound is required afterwards

- Leaves lines that can often be seen under the


- Extra covering material is required

- Leaves 70-90 mm from the wall

- Lots of dust, vibrations and noise

- Few areas of use



The grinding process which can remove sealants, coatings, tyre marks and surface imperfections. The process uses a series of metal-bonded diamond grit tools which perform the initial floor grinding. The quality and hardness of the existing floor dictates the number of steps or passes needed to ensure a good base. An enclosed grinding head along with continual intensive vacuuming keep dust levels at a minimum.
