What is Travertine?

Travertine is a distinctive natural stone known for its unique characteristics and appearance, making it a popular choice for various architectural and design applications. Here are further details about travertine, its features, differences from other natural stones, grading, types, and the importance of sealing

Formation and Characteristics

Natural and Heavy Stone

Travertine is a naturally occurring stone that forms in hot springs or caves. It is a dense and heavy stone, and a pallet of travertine can weigh 3200 lbs. or more.

Formation Holes

Travertine is characterized by the presence of holes within the stone, formed when carbon dioxide escapes during its formation process. These holes contribute to its unique appearance.

Differences from Other Natural Stones

Hardness and Appearance

Travertine differs from other natural stones like marble and limestone in terms of hardness and appearance. Despite its formation process, travertine falls outside the metamorphic rock category.

Grading of Travertine

Grade Determination

The grading of travertine is often based on the number of holes within the stone. Generally, a higher grade indicates fewer holes. Popular colors include Ivory, Beige, Walnut (light, medium, dark), Noce (dark brown), Silver, and Gold. Combinations of these colors are also available.

Travertine Tiles vs. Travertine Pavers

Thickness Differences

Travertine tiles are typically 0.5” thick, while travertine pavers have a greater thickness of approximately 1.25”. The difference in thickness makes each type suitable for specific applications.

Sealing of Travertine

Importance of Sealing

Sealing is recommended for travertine to resist stains and enhance the stone’s natural beauty. The sealing process helps protect the surface from absorbing liquids that could lead to stains.

Signs for Re-Sealing

If water readily absorbs into the travertine, it is an indication that re-sealing is necessary. Re-sealing helps maintain the stone’s durability and appearance over time.

Sealer Selection

Travertine can often be sealed with the same types of sealers used for concrete or brick. However, it is crucial to test any sealer in a small inconspicuous area first to ensure compatibility and colorfastness.

Regular Maintenance

To preserve the integrity of the seal and the stone, it’s essential to conduct regular maintenance and promptly clean any spills to prevent potential staining.

Conclusion

Travertine’s unique appearance, coupled with its durability and versatility, makes it a sought-after material for various applications, including flooring, countertops, and wall cladding. Proper understanding of its characteristics and appropriate maintenance, including sealing, ensures that travertine retains its beauty and functionality over time.
