Key Technical Points for Renovation and Retrofitting of GRC Components in Existing Buildings?

Renovating and upgrading GRC components on existing buildings requires comprehensive condition assessment, scientific design, and meticulous construction. Based on experience from multiple renovation projects, Qinglong Group has summarized a four-step method—inspection and assessment, scheme design, construction control, and quality verification—to ensure durable and reliable renovation results.

Condition inspection is the foundation of renovation. The extent of damage is determined through tap testing and infrared detection. In old building renovation projects, Qinglong Group employs drone high-definition imaging for comprehensive inspection, precisely locating problems. The assessment covers material strength, connection conditions, and substrate conditions, providing the basis for design.

Scheme design must be scientific and sound. Based on the inspection results, repair or replacement plans are formulated. Minor damage is repaired by grouting, while severe problems call for complete replacement. Qinglong Group emphasizes coordination between new and old components to ensure the overall effect. The design takes construction feasibility into account to avoid secondary damage to the original structure.

Construction control ensures quality. Old components are carefully removed to protect the substrate. New components are installed with precise alignment, and joints are tightly sealed. Comprehensive testing after construction ensures the renovation meets standards. Through these measures, GRC components on existing buildings are given new life.
