Unfilled travertine slabs are natural stone products that retain the stone’s inherent porous structure, with no resin or cement-based fillers applied to seal surface pores and voids—preserving travertine’s authentic, rustic aesthetic characterized by visible holes and texture. GHY STONE, a leading manufacturer since 1992, offers these slabs for projects seeking a raw, natural look, such as rustic residential patios, Mediterranean-style restaurant floors, or outdoor garden features. Sourced from quarries in Turkey’s Denizli (travertine with well-defined, uniform pores ideal for the unfilled look) and Italy’s Tivoli (premium travertine with natural color variations that enhance rustic appeal), the raw material adheres to standards for unfilled applications: density of 2.6–2.7 g/cm³ (maintaining structural integrity despite porosity), compressive strength of ≥105 MPa (withstanding outdoor foot traffic), natural porosity of 3–5% (preserving the authentic texture), and pore size of 0.5–2mm (visible but not excessive, balancing aesthetics and practicality). Fabrication focuses on preserving natural texture: CNC cutting produces slabs in standard sizes (60cm×60cm, 80cm×80cm) and custom dimensions, with thickness options of 20–30mm (for outdoor use) to 15mm (for indoor accent walls). Slabs are ground with 200–800 grit abrasives to smooth rough edges but retain pore structure, then treated with a penetrating, breathable sealant (silane-based, low-VOC) that protects against staining without filling pores—maintaining the stone’s ability to “breathe” (release moisture, preventing mold in outdoor use). Finishes are tailored to rustic aesthetics: tumbled finishes (textured, R11 slip rating) for patios, enhancing the natural rough feel; honed finishes (matte) for indoor accent walls, highlighting pore details without glare. Installation requires consideration for porosity: outdoor slabs are laid on a gravel substrate with drainage to prevent water pooling in pores; indoor slabs use moisture barriers under concrete substrates. Grout lines of 3–4mm (filled with sanded grout) accommodate texture. Maintenance involves regular cleaning with a dry brush to remove debris from pores, occasional wiping with pH-neutral cleaner (avoiding harsh chemicals that damage sealant), and resealing every 12–18 months (more frequent for outdoor use) to maintain stain resistance. GHY STONE’s unfilled travertine slabs deliver authentic natural charm for rustic and Mediterranean-style projects, reflecting the company’s commitment to preserving stone’s inherent beauty while ensuring durability.
