Post-Tensioned Slabs-on-Ground (SOG) for Industrial Facility Floor Structures

Introduction

This article is an official website version adapted from original content, revised for brand consistency, compliance, and data center formatting. It focuses on the Taiping solution for industrial facilities, highlighting project pain points, solution paths, value indicators, and application boundaries. Specific projects require professional review considering loads, column grids, soil conditions, construction schedules, operational methods, and approval requirements.

Client Concerns

• Traditional industrial floors have numerous saw cuts and construction joints, leading to edge spalling that affects forklifts, AGVs, and production continuity.
• Clean, heavy-load, and high-frequency traffic scenarios demand higher flatness, durability, and low maintenance.
• Floor solutions must be evaluated based on loads, soil conditions, production organization, and lifecycle maintenance.

Solution Highlights

• Taiping is an integrated floor system comprising three technical lines: post-tensioned integrated floor, UHPC integrated floor, and UHPC long-lasting repair.
• Post-tensioned integrated floor is suitable for industrial facilities and underground garages; cold storage facilities use UHPC integrated floor or UHPC repair, not post-tensioned.
• UHPC integrated floor and UHPC repair can be used in cold chain warehouses, industrial facilities, and underground garages.
• By reducing floor saw cuts by 80%, it minimizes edge spalling, dust, stepping, and operational disruptions from maintenance.

Main Content (Official Website Version)

Conventional concrete floors, especially in industrial facilities, often suffer from spalling, cracking, and deformation due to heavy equipment or temporary loads (goods, trucks, forklifts) combined with thermal stresses. Repairs significantly impact production and are costly. Post-tensioned slabs-on-ground (SOG) incorporate prestressing tendons (typically straight) to introduce compressive stress into the floor structure, enhancing crack resistance and reducing joint spacing. First applied in the 1950s in the United States, SOG gained rapid adoption. By 2003, over half of prestressing tendons in the U.S. were used in SOG.

Advantages

1. Enhanced Durability: Prestressing before loading prevents or reduces crack formation.
2. Higher Flexural Strength: Compared to conventional reinforced concrete floors of the same thickness, SOG offers better bending performance.
3. Greater Structural Stiffness: Prestressing increases foundation stiffness, mitigating damage from soil volume changes (e.g., expansive soils).
4. Reduced Construction and Maintenance Costs: Savings from reduced concrete and reinforcement quantities, fewer joints, shorter construction time, and lower maintenance.

Applications

• Industrial Facilities and Logistics Warehouses: Heavy loads and frequent traffic make SOG ideal for reducing cracks and maintenance.
• Residential Buildings: In states like Arizona, Nevada, Colorado, Louisiana, Florida, and Georgia, SOG foundations are common for homes on expansive soils.
• Sports Facilities: Tennis courts, basketball courts, and multi-purpose sports floors benefit from SOG's stiffness and low maintenance. The American Sports Builders Association recommends SOG for tennis courts.
• Other Types: Parking lots, helipads, highway pavements, airport runways, and high-rise building foundations.

BICP's post-tensioned integrated floor enables ultra-long spans without joints, reducing cracking and significantly lowering routine maintenance costs. Widely applicable in industrial facilities, logistics warehouses, supermarkets, precision manufacturing workshops, and ESD-controlled floors. Contact us for more information.

Application Boundaries and Publication Notes

• Taiping distinguishes three technical lines: post-tensioned integrated floor for industrial facilities and underground garages; cold storage uses UHPC integrated floor or UHPC repair, not post-tensioned.
