Country and Quarry Origin
High-grade sedimentary limestone quarries in Italy, large intact raw blocks with soft grey moca base, stable raw material for slab and tile deep processing.
Grey Moca Limestone Blocks For Interior flooring and Wall
Price : $80‑110 /MT
Grey Moca Limestone Block is natural sedimentary fossil‑bearing limestone mainly quarried from Turkey, silver‑grey base mixed with subtle earth‑moca tone with scattered fossil textures. Good workability and moderate weather resistance. Quarry blocks can be processed into slabs, tiles, cut‑to‑size for interior & exterior architectural projects. Needs sealing treatment for acid‑prone or wet areas to prevent erosion and staining.
Category: Limestone Blocks
Color: Grey
Product description
Grey Moca Limestone Blocks (Moca Grey Limestone Quarry Blocks) are among the most architectural, sophisticated, and globally specified raw stone materials in modern exterior construction and high-end facade design — a dense, fine-grained sedimentary limestone quarried from rich, mineral-dense geological formations. Its hallmark is a refined pale grey to smoky-ash background, characterized by subtle parallel graining, soft cream-grey striations, and uniform fossilized micro-inclusions that yield a harmonious, linear visual rhythm. Celebrated for its remarkable structural homogeneity, high density, and excellent thermal and acoustic insulation properties, this premium selection of raw limestone represents the benchmark for contemporary architectural stonework. Its well-squared block geometry, consistent physical grain, and outstanding workability make these raw quarry blocks the top-tier material of choice for high-yield slab slabbing, exterior ventilated facade panels, carved architectural columns, cut-to-size cladding, and commercial stone projects worldwide.
General Specifications
- Category: Limestone Sedimentary Natural Stone
- Color: Pale ash-grey, silvery-grey, and soft smoky ground with subtle linear graining, soft cream striations, and uniform micro-fossil accents
- Surface Finish Available: Saw-Cut (Raw Block) / Honed / Bush-Hammered / Sandblasted / Line-Chiseled / Brushed
- Block Form: Raw Quarry Block / Gangsaw Block / Architectural Monolith
- Texture: Uniform, fine-grained micro-crystalline matrix; linear grain alignment with smooth tactile feel and robust structural compactivity
- Density: 2.48 – 2.60 g/cm³ (High material density for limestone; excellent structural compactivity and mass)
- Water Absorption: 0.70 – 1.60% (Low-to-moderate porosity — standard for natural architectural limestone; easily sealed for stain and weather resistance)
- Compressive Strength: 75 – 105 MPa (Strong structural load-bearing capacity — highly suited for commercial exterior facades and ashlar masonry)
- Abrasion Resistance: Medium-High — demonstrates reliable durability for exterior wall paneling, architectural carving, and high-traffic paving
Processing & Machinery Assessment
GANGSAW & CIRCULAR SAW SUITABILITY
This block has been assessed as fully compatible with modern limestone gangsaw machinery, large-diameter circular block cutters, and diamond multi-wire saws. Standard block dimensions of L-(250–300) cm × B-(150–180) cm × H-(140–170) cm fall directly within the optimal range for high-yield architectural panel and slab production. Grey Moca Limestone’s uniform sedimentary structure and absence of hard silica nodules allow for smooth, low-vibration sawing, rapid cutting speeds, and minimal tool wear, making it an exceptional candidate for high-volume facade panel fabrication with high net recovery rates.
- Recommended Processing: Gangsaw or multi-wire slabbing (2.0 cm, 3.0 cm & heavy 5.0–10.0 cm architectural cladding panels), followed by face calibration, surface honing, sandblasting, or bush-hammering
- Expected Slab Yield: Approximately 68–78 slabs per block (based on 2.0 cm slab thickness)
- Finish Result: A smooth, velvety matte-honed or finely textured surface that illuminates its neutral grey tones while providing enduring weather resistance and a modern architectural aesthetic
About
Texture
Fine layered sedimentary texture, natural pore structure stable after quarrying, fits multi-type cutting and follow-up surface finish processing requirements.
Pattern and Veining
Uniform grey moca base with faint subtle mineral fine veins and tiny scattered speckles, low inter-block color difference, easy matched layout for finished products.
Durability
Stable indoor long-term use performance; outdoor application requires full penetrating anti-weather sealant, reliable lifespan for building facade and interior decoration projects.
Available Surfaces
Polished, Tumbled, Brushed, Honed, Split
Acid Sensitivity
Poor acid resistance with calcite as main component; acid liquid will corrode stone matrix, forbid acid detergent and long-term acid rain contact.
Physical Properties

Applications
Interior wall claddingInterior WallExterior Wall
Mineralogical Composition
Calcite91-94%
Chemical Properties
Main component CaCO₃ 90%-95%, low silica content, soluble carbonate reacts with acid leading to surface etching, gloss decline and color loss.
Installation Guide
Cut blocks into standard slabs first; wall cladding uses flexible stone adhesive; floor uses anti-crack mortar; exterior construction adopts full anti-acid penetrating sealant treatment.
Cleaning & Maintenance
Adopt neutral special stone cleaner only; regularly replenish sealant layer; wipe acid spills immediately to protect natural texture.
Custom Cutting
Support customized block dimensions, process into slabs, tiles and special-shaped components strictly per engineering drawings for project matching demands.
