Pierre Dordogne Limestone is a natural stone quarried from Les Eyzies-de-Tayac-Sireuil in the Dordogne region of France. Recognized for its aesthetic appeal, it features a straw-yellow hue and a fine grain texture. This limestone is renowned for its durability, non-slip properties, and resistance to weathering, making it an excellent choice for both indoor and outdoor applications.

Physical and Mechanical Properties

• Color: Straw-yellow
• Water Absorption: 0.82%
• Density: 2090 kg/m³
• Flexural Strength: 2 - 4 MPa
• Compressive Strength: 16.3 - 18.0 MPa
• Hardness: Typically rated on the Mohs scale (specific value not provided, but generally around 3-4 for limestone)
• Porosity: Although exact porosity is not specified, limestone tends to have moderate porosity, contributing to its absorption rate.
• Slip Resistance: High, due to its texture and finish options.

Chemical and Mineral Compositions (Approximate)

• Calcite (CaCO₃): Major composition, typically over 90%
• Quartz (SiO₂): Minor composition, varying amount
• Other Minerals: Trace amounts may include clay minerals, feldspar, and iron oxides contributing to the color variations.

Usage

Pierre Dordogne Limestone is highly versatile and can be used for:

• Flooring: Suitable for areas requiring non-slip properties.
• Wall Cladding: Both interior and exterior applications.
• Countertops: Offering a unique aesthetic in kitchens and bathrooms.
• Landscaping: Ideal for patios, pathways, and outdoor steps.
• Architectural Detailing: Suitable for moldings and trims.

Maintenance

• Regular Cleaning: Use a neutral pH cleaner to prevent damage.
• Sealing: Recommended every few years to enhance its longevity and resistance to stains.
• Avoid Acidic Cleaners: These can etch the surface and dull the finish.

Cutting Sizes (Common Dimensions)

• Commonly available sizes include:
• Flooring Tiles: 30 cm x 30 cm, 40 cm x 40 cm, and other custom sizes.
• Slabs and Countertops: Custom sizes per project requirements.
• Thickness: Varies, commonly 2 cm or 3 cm for tiles and slabs.

Surface Finish Options

• Honed: Smooth matte finish, enhancing the natural beauty of the stone.
• Polished: Shiny finish, though less common due to potential slip concerns.
• Brushed: Providing a textured finish, ideal for outdoor and high-traffic areas.
• Tumbled: Offering a rustic, aged appearance.

Pierre Dordogne Limestone is a prestigious material choice that combines aesthetic appeal with performance, making it suitable for high-end architectural projects and durable installations.
