We’ve been asked to address a problem with a small crack running through the marble in an entrance area. While the underlying problem is movement in the concrete slab under the tile (installed by others), an additional issue is matching the stone.
Natural stones like marble are just that — natural. The chances of duplicating the colors and veining in marble after several years are like finding the proverbial needle in a haystack. As you can see in this photo, marble is cut in quarries (this one 490+ feet deep so far) which produce tons of material each year. This material is shipped over the world, and tracing it back to a particular point of origin is often an impossibility.
While we can order samples, and try to get close, it’s doubtful that we’ll be able to keep the consistent look of the original installation. So, does the customer learn to live with the crack, accept an area of marble that isn’t the same color as the original, or remove the entire area and replace it with a new material?
Here’s the caution from us: When natural stone is used in an installation, it is imperative that extra material be ordered and stored as ‘attic stock.’ Make sure you ask your installer to order extra materials, and be sure you store them in a safe place so they’ll be available should you ever need them to preserve your installation.
