Design Concept · A Unified Stone Language for Retail

The major shopping center is built around "whole-mall unity": Calacatta Gold slabs for main entrance and atrium deliver a sense of occasion, Crema Marfil for flagship stores and upper floors provides warmth, and Steel Grey Granite for high-traffic corridors and back-of-house zones is durable and stain-resistant — three principal stones balance "ceremony" and "durability" across the retail space.

HENGSHENG MARBLE S&T CO. LIMITED Stone supplied and installed all stone for the 38,000 ㎡ across 8 floors: main entrance slabs, atrium flooring, escalator treads, public corridors, F&B areas, cinema lobby, restrooms, tenant partition walls, outdoor plaza paving and façade. Delivered floor by floor over 22 months while the center kept trading — weekend footfall of 150,000 with zero disruption.

Construction

Construction Process

Six stages from 3D scanning to floor-by-floor handover — 22 months of zoned delivery while the mall kept trading.

01

3D Scanning

3D Scanning

360° laser scanning of the 38,000 ㎡ across 8 floors produced millimetre-level point clouds, resolving 412 structural deviations and tenant interface points in advance.

02

Digital Layout

Digital Layout

14,000 ㎡ of Calacatta Gold slabs pre-assembled and numbered floor by floor, producing piece-by-piece installation drawings aligned with the floor-by-floor program.

03

Factory Fabrication

Factory Fabrication

Five-axis CNC machined 14,000 ㎡ of Calacatta slabs and 6,000 linear metres of escalator capping to a tolerance of ±0.5 mm.

04

Heavy-duty Packing

Heavy-duty Packing

Escalator-zone 30 mm thick slabs and Calacatta slabs travelled in steel-framed wooden crates — zero breakage throughout city delivery.

05

Night Installation

Night Installation

Noisy trades concentrated between 22:00 and 06:00 to avoid disrupting daytime trade; weekend footfall of 150,000 kept flowing with zero disruption across all 22 months.

06

Crystallised Polishing

Crystallised Polishing

Calacatta slab flooring siliconised and crystallised to a gloss of 90° or above, stain resistance grade 5; gloss still at 85° after three years in service.

Installation Details

Installation Details

Craft details up close — in a high-traffic retail venue, precision hides in the millimetres and the joints.

Seamless Joints

Seamless Joints

Calacatta slab joint flatness ±0.3 mm with elastic sealant; no cracking after 80,000 fatigue cycles.

Anti-slip Finish

Anti-slip Finish

Bush-hammered and anti-slip coated on escalator zones and public restrooms, anti-slip grade R10; wet-state coefficient of friction ≥0.62.

Curved Fabrication

Curved Fabrication

The concierge desk's stone radius edges were five-axis CNC machined, ±1 mm radius tolerance; no visible joints on the curved segments.

Waterproofing Detail

Waterproofing Detail

Public restroom stone walls were six-sided waterproof coated with sealed joints; zero penetration in a 48-hour immersion test.

Decorative Inlay

Decorative Inlay

A 4 m-diameter stone inlay at the main entrance, waterjet-cut from 18 different tile sizes; joint flatness ±0.5 mm.

Maintenance

Maintenance

Full re-grind each quarter and crystallisation each month; public-area gloss held at 85° or above after three years in service.

Technical

Technical Highlights & Solutions

An 8-floor retail space, 150,000 weekend visitors, and 320+ tenants trading throughout — HENGSHENG MARBLE S&T CO. LIMITED Stone answers with data.

🏪
CHALLENGE 01

Unity across 8 floors of retail

The mall spans 8 floors with 38,000 ㎡ of stone; tone, spec and flatness must match across floors, which is hard for single-floor work.

Solution:Three principal stones (Calacatta, Crema Marfil and Steel Grey Granite) cut from the same batch, factory pre-assembled and installed by floor number; cross-floor color difference ΔE ≤ 1.5, flatness tolerance ±0.5 mm.
👥
CHALLENGE 02

Wear resistance for 150,000 weekend visitors

Weekend footfall is 150,000 visitors — sole grime and high-frequency foot traffic quickly dull ordinary stone or make it slippery.

Solution:Calacatta slabs siliconised and crystallised to stain resistance grade 5; bush-hammered and anti-slip coated on escalator capping at grade R10; gloss held at 85° after three years.
CHALLENGE 03

22 months of zoned delivery, mall trading

The mall kept operating throughout, with 320+ tenants trading; works could not disturb the tenants, and noisy trades had to fit into night-time gaps.

Solution:Works were zoned across 8 floors, with noisy trades concentrated between 22:00 and 06:00; weekend footfall of 150,000 ran with zero disruption across all 22 months.
CHALLENGE 04

25 kPa tenant loads and fit-out

Tenants' fit-out and equipment average 25 kPa floor loads; ordinary stone flooring cracks or settles under them.

Solution:30 mm Steel Grey Granite on 50 mm reinforced concrete composite panels gives a load capacity of 80 kPa; maximum deformation ≤0.4 mm after tenants had occupied for five years.
