Thick travertine slabs are heavy-duty natural stone products defined by their substantial thickness (typically 25mm–50mm, compared to standard 12–20mm slabs), engineered for applications requiring enhanced structural stability, durability, and resistance to heavy loads or impact. GHY STONE, a trusted manufacturer since 1992, produces these slabs for high-stress residential and commercial uses such as outdoor patio flooring, commercial plaza paving, kitchen countertops (especially those supporting heavy appliances like ranges or refrigerators), and public seating structures. Sourced from quarries in Iran’s Naein (travertine with high density of 2.7–2.8 g/cm³ and exceptional compressive strength, ideal for load-bearing applications) and Spain’s Alicante (travertine with low porosity of 1.8–2.2% pre-treatment and uniform grain structure, ensuring consistent thickness and durability), the raw material meets rigorous performance standards: compressive strength of ≥125–140 MPa (withstanding heavy loads like commercial furniture, outdoor dining sets, or foot traffic in public plazas), water absorption of ≤0.3% post-filling (resisting outdoor moisture, rain, or spills from commercial kitchens), abrasion resistance of ≤0.1mm loss per ASTM C241 (preventing wear from frequent use), and freeze-thaw resistance (ASTM C666, withstanding 100+ cycles without cracking, critical for outdoor use in cold climates). Fabrication processes emphasize structural integrity: CNC diamond cutting uses high-torque machinery to achieve precise, uniform thickness (tolerance of ±0.2mm across the slab) and custom dimensions—including large 300cm×150cm slabs for commercial plazas or 60cm×120cm slabs for kitchen countertops. Vacuum-assisted resin filling employs commercial-grade, waterproof resins to seal pores, reinforcing the slab’s structure and preventing moisture penetration that could lead to cracking under heavy loads. Slabs are ground with 200–2000 grit abrasives to create a smooth or textured surface, then treated with a high-performance, UV-stable sealant (for outdoor use) or commercial-grade sealant (for indoor use) that enhances scratch resistance and durability. Finishes are optimized for heavy-use scenarios: textured finishes (like brushed or tumbled, with an R12 slip rating per EN 14411) for outdoor patios or plazas, ensuring safety when wet; honed finishes for kitchen countertops, hiding minor scratches from heavy cookware; and polished finishes for high-end commercial reception desks, adding a premium appearance while maintaining durability. Installation requires specialized preparation, including reinforced concrete substrates (to support the slab’s weight, which ranges from 65–125 kg/m² depending on thickness), high-strength epoxy adhesives (for indoor countertops) or mortar with added fiber reinforcement (for outdoor paving), and wider grout lines of 3–5mm (filled with sanded, waterproof grout to accommodate thermal expansion in outdoor environments). Maintenance involves periodic cleaning with pH-neutral commercial stone cleaner (for indoor use) or pressure washing (low pressure, ≤1500 PSI) for outdoor slabs, with resealing every 36–48 months to maintain protection. GHY STONE’s thick travertine slabs deliver exceptional longevity and performance in high-stress applications, aligning with the company’s commitment to excellence and premium stone solutions for both residential and commercial projects.
