Rink Floors: Laser Grading

In construction, the quality of the finished product is determined by the quality of the foundation. This is especially true when building ice-rink floors. Two essential steps are Laser Grading and Subsoil Heating.

Laser Grading is a fine-grading process done on the lower-sand layer and is often regarded as the single most important factor affecting the quality and energy-efficiency of the ice sheet.

Having a perfectly level, compacted base on which to build a rink is even more important to the outcome of the floor than the ice-rink piping itself. An equipment manufacturer has designed the Laser-operated Grader specifically for Roustan Refrigeration, to automate the entire fine-grading process to laser-perfected tolerances. A Roustan Refrigeration-trained operator drives the machine over the rink bed. The laser control does the work, readjusting the blade every half-second. The outcome is a true and consistent floor that measures dead-level over the entire ice sheet.

Custom manufactured, the Laser-operated Grader is precision industrial equipment. It has been provided to Roustan Refrigeration specifically to meet the rigid demands of an ice rink application. An automated laser controls the machine's hydraulic system, grading to a very close tolerance. Precision like this is possible only with our machine.


  • Reduced construction window for rink installation. Grader eliminates several days' work.

  • Better energy efficiency for rink because ice is smooth. No high spots caused by tolerance flaws.

  • More consistent ice temperatures. True leveling of the base for the rink-piping system means no more soft spots.

  • Noise and excessive cracking of sand floors reduced because insulation sheets lay flat against sand base.

  • Improved performance. Skaters report that ice made on a laser-graded, sand-base floor feels and performs like ice over concrete flooring.

  • Easier to maintain. Begin with level surface, ice thickness remains even and easy to care for.

  • For concrete floors, too, laser grading provides the best possible structural integrity by developing a solid base first.
