Yes, terrazzo repair is possible.
This example is from a floor in an old business in the North Shore of Pittsburgh that was converted into a residence. Initially from Connecticut, Chase Brass and Copper company had an mill warehouse in Pittsburgh. It closed sometime around 1960, but Chase still operates in Montpelier, Ohio.
This terrazzo floor features the Chase logo in an art deco layout: white, yellow, green and burgundy geometric inlays. Overall, this terrazzo section was in good shape, but it had around 40 holes in it that had been filled with concrete. Some were big, and some were little.
Unfortunately with the morning sun streaming through the windows, a good before photo was hard to get. Here’s an example of one of the larger holes:
The first challenge is to order the right marble chips for the floor. Within each color section, are different colors of marble chips. And different sizes. So we had to order 14 different types of marble chips for this job (and there were thankfully no repairs needed in the burgundy areas.)
The next step is to remove ALL of the concrete “repairs.” If even a little bit of concrete remain in the holes, you would definitely be able to see the edges of the repairs:
Then the filling begins, first stuffing in with the various sizes and colors of the marble chips, and then the epoxy that holds them together…
Then each filled area needs to be ground down by hand, to match the surface area of the floor:
After this, the entire floor is resurfaced to remove damage, and then refinished to bring it back to a new condition.
Here’s the floor, after restoration and polishing:
