Travertine is a natural stone that can be used for a variety of applications, both interior and exterior. Turkeys Eco Medium Travertine can generally be used in exterior applications, but its suitability for very rainy climates may depend on several factors.

While travertine is known for its durability, it is a porous material and can absorb water. In areas with heavy rainfall, this can potentially lead to water damage, erosion, or discoloration of the stone over time. However, there are several measures that can be taken to mitigate these risks:

1. Sealing: Applying a high-quality sealant to the travertine can help protect it against water absorption. Regular maintenance and resealing may be necessary to ensure its effectiveness.

2. Proper installation: The correct installation techniques, such as using adequate mortar and ensuring proper drainage, can help prevent water from accumulating on the surface or behind the stone.

3. Sloping: Properly sloping the surface where the travertine is installed can help redirect water away from the stone, reducing the chances of water damage.

4. Maintenance: Regular cleaning and maintenance, including removing any organic debris or stains promptly, can help prolong the lifespan and appearance of the travertine.

It is recommended to consult with a professional stone supplier or installer who can assess the specific site conditions and provide guidance on the suitability of Turkeys Eco Medium Travertine for your particular climate and application.
