HTC Superfloor™ - Definition
HTC Superfloor™ is a complete concept for polishing concrete. The method mechanically refines the concrete surface by removing the top cement paste and exposing the underlying, stronger concrete. The existing concrete is grinded and polished according to a dependable and thoroughly tested method with HTC’s effective machines and diamond tools. The result is a floor with a completely even surface of a high quality, both functionally and esthetically. To achieve all technical benefits demanded for calling the surface a HTC Superfloor™, the grinding sequence must be performed according to the prescribed method, with polishing steps to a minimum of 3000 grit, FP 60 green polishing step in the HTC Grinding Guide.
Several factors will affect the final appearance.
- The stone quality and color. In Sweden the ballast material mainly consists of granite in different fraction sizes.
- The color of the cement (the cement can be pigmented).
- The concrete quality. The strength is measured in Mpa (megapascal) 1Mpa=10kp/cm².
- Grinding depth: With different grit sizes and bonding matrix in the diamond segments you can somewhat control how deep you grind into the concrete surface. The grinding depth will affect how much of the stones that is exposed and also in turn the aestehetical appearance of the polished surface.
The technical advantages with a HTC Superfloor™ has been verified in several test att the Swedish National Testing and Research Institute, SP (SP 99B4, 4806) (SS 13 72 41) (prEN 13892-3, Böhme) (EN 14617-3).
