Noir Sully Limestone is a premium black fossilized limestone known for its homogeneous texture and compact composition. Quarried in Belgium, particularly in Soignies, Ecaussinnes, Sprimont, and Mons, this stone features a deep black background interspersed with subtle fossilized remains, adding a natural, historic charm to its appearance. It is widely appreciated for its durability, aesthetic appeal, and versatility in both modern and classic architectural projects.

Texture & Pattern

• Texture: Noir Sully Limestone is very fine-grained and compact, offering a smooth and uniform surface.
• Pattern: It exhibits a homogeneous deep black color with occasional fossilized inclusions that provide natural character without overwhelming the uniformity of the stone.
• Visual Appeal: Due to its dark color and minimal veining, it creates an elegant and sophisticated look, making it a preferred choice for luxury applications.

Physical & Mechanical Properties

• Apparent Density ... ASTM C97... 2687 kg/m³
• Porosity ... - ... 0.28%
• Water Absorption ... ASTM C97 ... Very low/0.19 %
• Compressive Strength ... ASTM C170 ... 157.9 MPa
• Modulus of Rupture ... ASTM C99 ... 16.7 MPa
• Slip Resistance ... Varies by finish ... Moderate to high (depending on finish)
• Durability: High compressive strength and very low porosity make it a highly durable stone, suitable for heavy-traffic areas and exterior applications.
• Weather Resistance: Excellent frost and thermal change resistance, making it ideal for both indoor and outdoor use.

Chemical & Mineral Composition

• Calcium Carbonate (CaCO₃)...96-98%
• Silica (SiO₂)...1-2%
• Iron Oxides (Fe₂O₃)...< 0.5%
• Magnesium Carbonate (MgCO₃)...0.2-0.5%
• Mineral Composition: Primarily composed of calcite, with minor traces of quartz and other minerals that contribute to its compact structure.

Hardness & Porosity

• Hardness: Noir Sully Limestone is moderately hard, allowing for intricate cutting and carving while maintaining good resistance to wear.
• Porosity: Extremely low (0.28%), meaning it is highly resistant to water absorption and staining compared to other limestones.
• Slip Resistance: Depends on the surface finish. Honed or brushed finishes provide better grip than polished surfaces.

Usage Applications

Noir Sully Limestone is a versatile stone used for both interior and exterior applications, including:

• Flooring (residential and commercial)
• Wall cladding Staircases & risers
• Countertops & vanity tops
• Fireplace surrounds
• Sinks & decorative objects
• Urban paving & landscaping
• Pool coping & outdoor patios

Its low porosity and high density make it an excellent choice for areas exposed to moisture or high wear.

Maintenance & Care

• Sealing: Due to its low porosity, Noir Sully Limestone does not require frequent sealing, but it is recommended in areas exposed to heavy staining agents.
• Cleaning: Use pH-neutral cleaners to avoid etching. Avoid acidic substances like vinegar or citrus-based cleaners.
• Polishing: If a polished finish is used, occasional repolishing may be necessary to maintain the high-gloss look.

Cutting Sizes (cm) & Availability

Noir Sully Limestone is available in custom sizes based on project requirements. Standard sizes include:

• Tiles: 30x30, 40x40, 60x30, 60x60 cm
• Slabs: 2 cm and 3 cm thickness (custom thickness available upon request)
• Cut-to-size elements for stairs, wall panels, countertops, and architectural details

Surface Finish Options

Noir Sully Limestone can be processed into various finishes, allowing it to adapt to different design needs:

• Polished: High-gloss finish that enhances the deep black color, suitable for luxury interiors.
• Honed: Smooth, matte surface that provides a subtle, elegant look, ideal for floors and walls.
• Brushed: Textured surface that gives an aged appearance, increasing slip resistance for outdoor use.
• Sandblasted: Rougher surface with a slightly faded black tone, used for exterior cladding and anti-slip applications.
• Bush-hammered: Heavily textured finish for landscaping, outdoor paving, and staircases.

Noir Sully Limestone is a premium black limestone with a homogeneous texture, fossilized inclusions, and exceptional durability. Its high compressive strength, low porosity, and versatility make it an ideal choice for luxury architecture, urban design, and high-end interior spaces. Whether polished for a refined indoor setting or brushed for a rugged exterior application, Noir Sully remains a timeless and sophisticated stone.
