Hotels, malls, airports and estates use huge volumes of stone with high demands. Driveways, paving, coping and curtain walls each have distinct selection logic; wrong choice means endless repair. This guide uses Hong Kong large-project experience.
Driveways & Paving: Wear & Load First
Driveways and plaza paving bear vehicles and weight — granite is the pick. High hardness and compression, with flamed or bush-hammered slip-resistant faces. Marble is too soft for driven areas. See the outdoor granite guide.
Paving: Anti-Slip Finish Is Key
Outdoor paving must resist slip beyond wear. Hong Kong's long rainy season calls for honed or textured faces, not polish. Slab thickness and mortar fullness affect durability; inspect on site.
Coping: Drainage & Drip
Wall caps, planter and pool coping must slope outward to stop water entering walls. Add a drip underneath, with adequate thickness (30mm+) to withstand weather and foot traffic.
Curtain Wall: Dry-Hang Is Safest
Large marble facades use dry-hang systems (pin, clip, undercut bolt); adequate slab thickness and back-net reinforcement, with acceptance on hollow, flatness and joint width. See the facade guide. HENGSHENG worked on projects like the Hong Kong airport.
Procurement Points
- Pick stone by function per zone, not one stone everywhere;
- Require same-batch source to avoid colour difference;
- Write fabrication tolerance and sealing into the contract;
- Keep reference samples and inspect by batch.
Use an Experienced Team
Engineering stone needs supply stability and install discipline; book a free survey and project talk for detailing and quote to cut rework.
