Marble and Granite Testing Services
Ensuring the aesthetic quality, physical durability, and performance of natural stone for construction and interiors.
Preserving Beauty and Strength
Quality Assurance for Natural Stone
Natural stones like **Marble and Granite** are selected not just for their beauty, but also for their inherent strength and longevity. However, geological variations mean that proper laboratory testing is vital to ensure structural integrity and resistance to wear, staining, and weathering.
Our **Natural Stone Testing laboratories** perform a range of specialized physical and mechanical analyses—including **Flexural Strength, Water Absorption, and Abrasion Resistance**—all strictly complying with Indian Standards (IS) and international protocols. We help suppliers, architects, and builders certify that their chosen stone materials are fit for purpose, whether for high-traffic flooring, exterior cladding, or ornamental finishes.
Key Physical and Mechanical Tests
We test properties essential for the structural and aesthetic performance of marble, granite, and other natural and polished stones.
Compressive Strength
Determines the maximum load a stone can bear before crushing, crucial for load-bearing structures and flooring applications.
Test Method: IS 1121 (Part 1)
Water Absorption
Measures the amount of water absorbed by the stone, which indicates porosity and susceptibility to freezing damage and staining.
Test Method: IS 1124
Modulus of Rupture (MOR) / Flexural Strength
Evaluates the stone's ability to resist bending stress, highly important for cladding, thin slabs, and countertop installations.
Test Method: IS 1121 (Part 3)
Specific Gravity and Density
Determines the mass per unit volume of the stone, necessary for structural calculations and assessing material quality.
Test Method: IS 1122
Abrasion Resistance / Hardness
Measures the stone's resistance to wear from friction and foot traffic, critical for flooring and high-use areas.
Test Method: IS 1124 / ASTM C241
Coefficient of Linear Thermal Expansion
Checks how the stone reacts to temperature changes, vital for exterior cladding and installations in varied climates.
Test Method: IS 1528 (Part 12)
Durability and Weathering Resistance
Tests include resistance to freezing-thawing cycles and acid/alkali exposure, ensuring long-term performance.
Test Method: IS 1528
Dimensional Tolerance
Ensures the slab or tile dimensions (length, width, thickness, squareness) meet the required specifications for installation.
Test Method: IS 1130
