Terrazzo is a composite material, poured in place used for flooring and wall treatments. It contains chips of marble, quartz, granite, glass, or other material, that is sprinkled into a binder. Terrazzo is cured and then ground and polished to a beautilfully smooth surface.


Terrazzo can come in any color combination and the pattern designs are limited only by the imagination. With modern technology, terrazzo can now be integrated with fiber optic technology to provide a flooring work of art.


Aside from periodic restoration of the wear surface area, terrazzo will last forever.


That's what Substrate Technology and their distributors can do for you! STI manufactures and supplies the world's best diamonds for the restoration of terrazzo surfaces. With our products and knowledge, we can take an epoxy, carpet, or vinyl tile covered terrazzo floor and bring it back to the beautiful, durable, and timeless floor system it was the day it was installed.

For polished terrazzo, we offer the following tools:

  • TPS Diamond System — our high quality, wet process polishing system
  • STI Terrazzos — specialized matrix for aggressive cut with fine scratch pattern
  • STI Terrazzo Plus — same as "Terrazzos" plus 70% more abrasives, a self-opening profile, and an identifying colored layer when pad gets too low
  • Terrazzo REDZ — for wet polishing epoxy- and portland-based terrazzo & stone
  • Terrazzo-M Pads — less expensive and thinner version of STI Terrazzo; excellent as stratch remover

TPS Diamonds — a system for Terrazzo first cut and polishing — plus, the EG Grout Pans for filling pin holes!

VIDEO - TPS Diamond System: Understanding the STI Grout Pans

STI grout pan inventor, Eric Gallup, explains the process of how the STI Grout Pans work on the P/M machines.

Then we demonstrate how epoxy terrazzo is properly ground, air holes are filled, and a natural polish is attained using the TPS System from STI that thoroughly processes and treats a new or existing epoxy terrazzo floor.
