Travertine paving slabs are durable natural stone products engineered for outdoor and high-traffic indoor flooring applications, designed to withstand weathering, heavy foot traffic, and temperature fluctuations while retaining a natural, earthy aesthetic. GHY STONE, a trusted manufacturer since 1992, produces these slabs for use in residential patios, commercial plazas, hotel pool decks, garden pathways, and indoor spaces like restaurant terraces or shopping mall atriums, combining functionality with organic design appeal. Sourced from select travertine quarries in Turkey’s Denizli (for travertine with uniform pore structure and warm beige tones, ideal for residential patios), Iran’s Naein (for dense travertine with high compressive strength and gold-brown hues, suited for commercial plazas), and Spain’s Alicante (for light gray travertine with subtle veining, perfect for modern pool decks), the raw material meets rigorous performance standards: density of 2.65–2.75 g/cm³ (ensuring load-bearing capacity), compressive strength of ≥120 MPa (ASTM C170, withstanding heavy furniture or foot traffic), freeze-thaw resistance (ASTM C666, surviving 100+ cycles without cracking, critical for cold climates), slip resistance of R11–R12 (EN 14411, ensuring safety when wet), and water absorption of ≤0.5% post-filling (preventing moisture penetration and mold growth). The fabrication process begins with CNC diamond cutting to produce slabs in standard sizes (60cm×60cm, 80cm×80cm, 60cm×120cm) and custom dimensions (up to 150cm×300cm for large commercial plazas), with thickness options of 20mm–30mm (20–25mm for residential pathways, 25–30mm for commercial plazas to handle heavier loads) and a flatness tolerance of ±0.2mm/m. Most travertine paving slabs undergo vacuum-assisted resin filling (using outdoor-grade, color-matched resin) to seal natural pores, preventing dirt accumulation and water infiltration while preserving the stone’s natural texture; unfilled options are also available for projects seeking a more rustic look, though they require more frequent maintenance. Surface finishes are optimized for outdoor use: tumbled finishes (weathered, textured surface with rounded edges) enhance slip resistance and rustic charm, ideal for garden pathways; honed finishes (smooth, matte surface) offer a clean, contemporary look for pool decks; and brushed finishes (subtly textured) balance slip resistance and aesthetics for restaurant terraces. A final application of a UV-stable, waterproof sealant (polyurethane-based for outdoor slabs) protects against fading from sunlight, staining from oil or dirt, and chemical damage from pool chlorine or garden fertilizers. Installation requires site-specific preparation: outdoor slabs are laid on a compacted gravel or sand substrate (to ensure drainage and prevent shifting) with a 2% slope for water runoff; commercial plazas may use reinforced concrete substrates for added stability; grout lines of 3–5mm are filled with sanded, weather-resistant grout (or polymeric sand for outdoor applications) to accommodate thermal expansion and prevent weed growth. For indoor use (e.g., mall atriums), slabs are installed using polymer-modified mortar on concrete substrates, with moisture barriers to prevent subfloor dampness. Maintenance varies by finish: outdoor slabs require semi-annual cleaning with a pressure washer (low pressure, ≤1500 PSI) to remove dirt and algae; annual resealing to maintain water resistance; and occasional spot cleaning with a pH-neutral stone cleaner for oil spills. Unfilled slabs need more frequent sealing (every 12–18 months) to prevent staining. GHY STONE’s sustainable practices include quarry water recycling (reducing water waste by 75%) and waste repurposing (offcuts are used as aggregate for landscaping or small paving stones), aligning with green construction goals. Whether used to pave a residential patio, surface a commercial plaza, or line a hotel pool deck, travertine paving slabs deliver long-lasting durability, natural beauty, and safe performance, embodying GHY STONE’s commitment to premium stone solutions for high-traffic and outdoor applications.
