TRAVERTINE & LIMESTONE
Limestone deposits exist in all continents of the earth. Despite the common and traditional reference to "travertine marble", travertine is really a type of limestone. It is actually the terrestrial (land) formed version of limestone, as opposed to the marine based formations of many other limestone varieties.
Many varieties of travertine and limestone have enjoyed a successful history of exterior application, and some of the most prominent government and financial institutions worldwide proudly display limestone as their exterior cladding. Despite the popularity of exterior vertical limestone applications, the number of limestone varieties with successful history in exterior paving applications, particularly in freeze/thaw environments, is relatively limited.
Since these stones are some of the softer varieties of natural stone materials, they have long been a popular choice for intricately carved features and moldings, as well as statuary.
Limestone and travertine, like marble, are of a calcium carbonate base, and as such, are vulnerable to alteration by exposure to mild acids. A wide variety of stones are included in this group, and absorption varies from slight (<1%) to high (>10%). The combination of acid sensitivity and absorption limit the number of varieties that are suitable for countertop applications, and the user of limestone countertops should be well educated in its properties to accurately anticipate its behavior in service.
