Saint Pierre Linear Limestone is a premium architectural limestone quarried in Havre Saint-Pierre, Quebec, Canada. This stone is celebrated for its modern appeal, offering a warm and distinguished character that blends urban luxury with the timeless elegance of natural stone. Below is a detailed specification covering its texture, pattern, physical and mechanical properties, chemical composition, usage, finishes, and maintenance:
Appearance & Texture
Color Tones: Neutral to warm chocolate browns, occasionally highlighted with taupe or subtle gray undertones.
Pattern: Defined by linear horizontal veins—soft wave-like striations that create a flowing, layered effect.
Cut Options:
- Linear Cut (Vein Cut): Enhances the parallel veining for a sleek, contemporary look.
- Fleuri Cut (Cross Cut): Opens the pattern with more random movement, offering a more natural and organic appearance.
Texture: Smooth to the touch; naturally compact and fine-grained with occasional fossil and shell inclusions due to its marine sedimentary origin.
Physical & Mechanical Properties
- Water Absorption .... 0.14 % by weight
- Density .... 2708 kg/m³ (2.708 g/cm³)
- Flexural Strength .... 7.96 MPa
- Compressive Strength .... 119.6 MPa
- Porosity .... Low (typically < 2%)
- Hardness (Mohs) .... Approx. 3 – 4 (Limestone)
- Slip Resistance (Dry) .... ~ R10 (depending on finish)
- Slip Resistance (Wet) .... ~ R9 – R10
Chemical Composition (% by weight)
Typical of marine limestones:
- CaCO3 (Calcium Carbonate) .... 90 – 95%
- MgCO3 (Magnesium Carbonate) .... 1 – 3%
- SiO2 (Silica) .... 1 – 2%
- Fe2O3 (Iron Oxide) .... <1%
- Al2O3 (Aluminum Oxide) .... <0.5%
- Organic matter, fossils, trace elements .... <1–2%
Surface Finish Options
- Honed – Smooth matte finish, ideal for walls and floors
- Polished – Glossy, refined look enhancing the veining
- Brushed – Textured and antique feel, adds slip resistance
- Sandblasted – Subtly rough, ideal for exterior surfaces
- Tumbled – Aged and softened appearance, often for tiles
- Bush-Hammered – Rugged texture for slip-resistance
Cutting Sizes (cm)
Slabs:
- Typically 2cm and 3cm thickness
- Custom slab dimensions: e.g., 250 x 140 cm
Tiles:
- Standard sizes: 30x30, 40x40, 60x60, 30x60, 40x80 cm
- Custom cut-to-size available for cladding, flooring, and facades
Typical Applications
- Interior flooring & wall cladding
- Bathroom vanities & backsplashes
- Feature walls & fireplaces
- Exterior cladding and facades (sealed)
- Staircases, thresholds, and pool decks (textured finish)
Maintenance
- Sealing recommended, especially in wet areas or high-traffic zones
- Use pH-neutral stone cleaners
- Avoid acidic or abrasive substances
- Periodic resealing (every 1–2 years) to maintain protection and color
- Easy to maintain due to low water absorption and compact grain
Summary
Saint Pierre Linear Limestone is a hard, compact, and durable limestone suitable for a wide range of interior and exterior architectural applications. Its distinctive veining and neutral warm tones lend elegance and urban sophistication to both contemporary and classic designs. Its marine fossil inclusions, combined with its technical performance, make it both aesthetic and structurally reliable.
