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.
