How to Maintain GRC? A Complete Analysis of Qinglong's Scientific GRC Maintenance System

Scientific maintenance of GRC products is key to ensuring their long-term performance. As an industry-leading enterprise with 28 years of experience in GRC R&D and manufacturing, Qinglong GRC has established a comprehensive “prevention first, combined prevention and treatment” maintenance system based on extensive engineering practice data. According to follow-up surveys, GRC projects that implement scientific maintenance can extend their service life by more than 30% and reduce maintenance costs by 40%.

In the Shenzhen Yirui Biotechnology Building project, the specialized maintenance plan developed by Qinglong for its GRC curtain wall system has achieved remarkable results. The plan includes a multi-level maintenance mechanism consisting of quarterly inspections, annual testing, and triennial overhauls. Over the 5 years of operation, quarterly drone inspections have promptly identified and addressed 3 potential issues; the annual comprehensive testing combines infrared thermal imaging with the tapping method to systematically check for hollowing and cracking; the triennial overhaul focuses on addressing sealant aging at joints. This systematic maintenance has kept the building's GRC curtain wall at an integrity rate of over 98% to date, with maintenance costs accounting for only 0.8% of the construction cost per year, far below the industry average.

Regular Inspection System

Establish a quarterly inspection mechanism focusing on key areas such as joints and anchoring points. Use drones equipped with high-definition cameras for large-area inspections, improving efficiency by 5 times. Annual comprehensive testing should include load-bearing capacity verification and material performance testing. Such preventive inspections can identify hidden risks in a timely manner.

Cleaning and Maintenance Standards

Perform routine cleaning every 6 months using pH-neutral specialized cleaning agents. Clean promptly after sandstorms or acid rain to prevent corrosion. Water pressure during cleaning should be controlled at 3-4 MPa, and water temperature should not exceed 60℃. These standards can prevent secondary damage.

Repair Treatment Standards

Cracks with a width of ≤0.2mm should be treated with low-pressure grouting. Localized hollowing with an area of ＜0.1㎡ can be locally reinforced. Loose anchoring components must be replaced immediately. These standards ensure repair quality.

Enhanced Protection Measures

Reapply protective agents every 5 years to improve stain resistance. Coastal areas require more frequent anti-corrosion treatment. Impact protection devices can be installed at critical locations. These measures extend the service life.

Scientific maintenance requires systematic planning. It is recommended to develop a detailed maintenance manual and select a professional team for implementation. Qinglong GRC provides comprehensive after-sales maintenance guidance services.
