Concrete Grinding


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 covering

- 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. 

Grinding Concepts

Four different grinding levels

HTC Superfloor™ Platinum

Platinum produces the glossiest finish and is the concept we normally recommend to our customers. It involves more grinding stages than the other concepts. The result is an unbeatably durable floor. Truck wheels and substances leave no marks on the glossy surface and light reflects gently off the floor.

HTC Superfloor™ Gold

Using the Gold concept, you do not grind as deep into the concrete as with Platinum. This means that less ballast is exposed. Just like the other concepts, Gold then involves polishing the floor with HTC Twister™ to achieve a gloss that is almost as brilliant as a Platinum finish. Gold produces a floor with excellent resistance to marks from truck wheels, etc. HTC Superfloor™ Gold is ideal for concrete floors that are already even and level.

HTC Superfloor™ Silver

The Silver concept is a version of Platinum. Using this concept, you grind as deep into the concrete as with Platinum, but do not polish it. The ballast is exposed as with Platinum. Silver is therefore excellent if you want a floor with a matt surface finish.

HTC Superfloor™ Bronze

Bronze is the concept with the least number of grinding and polishing stages. This concept does not involve exposing the construction concrete. Instead, the top layer of the surface paste is polished but not removed. This process creates a stronger surface paste with a shiny finish.
