Amazon Fulfillment Center Project in San Bernardino
This project consisted of a time-sensitive concrete removal and replacement operation at an Amazon fulfillment center located in San Bernardino. The scope involved approximately 1,500 square feet of heavily deteriorated concrete within a high-traffic truck driveway that operates continuously on a 24/7 basis. Due to the critical nature of the access point, the project was required to be completed within a strict 48-hour window, with full return-to-service capability for heavy truck traffic immediately following completion. The project began with the complete demolition and removal of the existing damaged concrete slab. All unsuitable subgrade material was excavated and removed to eliminate compromised soil conditions that could affect long-term performance. Following excavation, new base material was installed and mechanically compacted to achieve proper density and provide a stable foundation for the new concrete section. Once subgrade preparation was completed, reinforcing steel (rebar) was installed throughout the repair area to enhance structural integrity and load-bearing capacity. Careful attention was given to reinforcement placement to ensure proper coverage and alignment in accordance with industry standards for heavy-duty pavement applications. Due to the accelerated schedule, a high-early-strength (fast-setting) concrete mix was utilized to meet the required turnaround time. On the second day, the new concrete was placed, properly consolidated, and finished with a broom texture to provide adequate surface traction for continuous truck traffic. All finishing operations were performed with precision to ensure a uniform surface profile and long-term durability under heavy use conditions. The selected concrete mix was specifically designed to achieve rapid strength gain, allowing the area to be reopened to full truck traffic within 24 hours of placement. This approach ensured minimal disruption to facility operations while maintaining the structural performance requirements of the pavement. The completed project delivered a fully restored concrete surface capable of supporting constant heavy vehicular loading. The combination of proper subgrade preparation, reinforcement installation, and the use of high-performance rapid-set concrete resulted in a durable, long-lasting solution tailored to the demands of a high-volume logistics environment.
