We use planetary machines on the concrete slabs to profile the surface to prep it for polish or coatings. When the grinder is turned on, the drum will rotate one direction, while the planetary head will counter rotate. Combining this with the forward movement of the machine, we create a cut pattern on the surface much like a round repeating “spirographic pattern” laid on top of each other, millimeters apart.
When looking down these cut patterns, they look like fine lines, or shallow grooves, cut into the surface. Now imagine you can view this closely. The view would seem like mountain peaks in front of mountain peaks — for as far as you can see.
