Every paving and cladding material has physical trade-offs. Module 11 provides an objective, evidence-backed engineering comparison between Tianya high-density bioclastic limestone (<0.22% absorption, 128.5 MPa) and European quarries, porous travertine, quartz sandstone, basalt bluestone, and 20mm outdoor porcelain.

Applicable Scope & Boundary Conditions: Used for value-engineering presentations and material selection workshops with architects and property owners.
| Verification Dimension | Authoritative Evidence & Technical Specification |
|---|---|
| vs. European Quarries (Burgundy / Moleanos / Jura) | Matches or exceeds ASTM C97/C170 density while reducing FOB cost by 40–60% and cutting custom CNC lead time from 12+ weeks to 2–3 weeks. |
| vs. 20mm Outdoor Porcelain Tiles | Natural limestone stays 8–12°C cooler underfoot in full sun, carries solid through-body color for bullnose/drop-face coping without glued mitre joints, and develops an authentic patina. |
| vs. Unfilled Travertine & High-Porosity Shell Stone | Sub-0.22% absorption prevents freeze-thaw spalling and salt-crystal pitting without requiring resin filler patching. |
Dark basalt absorbs intense solar radiation, reaching 55–65°C in summer sun and burning bare feet, whereas light cream and silver-grey limestone (Guyu, Hanbai, Qinghe, Yuebai) reflects solar heat and stays comfortable barefoot.
Trading companies broker orders across fragmented small workshops without unified block selection or dry-lay space, leading to thickness variations and shade mismatch. Tianya controls the quarry block, 5-axis CNC sawing, and 3,000 m² dry-lay hall under one roof.
