GRC Component Renovation Technology for Existing Buildings | Qinglong Professional GRC Retrofit Solution

Renovation and upgrading of GRC components on existing buildings comprises four major stages: inspection and assessment, scheme design, construction organization, and acceptance evaluation. Through non-destructive testing (strength, carbonation depth, rebar corrosion), calculation and analysis (load-bearing capacity, durability), and process comparison, an economical and rational renovation scheme is formulated. During construction, care should be taken to protect the existing structure, minimize disruption, and ensure safety.

Renovation techniques: surface cleaning (pressure ≤0.3MPa), crack grouting (grout fluidity ≥260mm), partial repair (bond strength ≥1.5MPa), and protective treatment (durability ≥20 years). After renovation, the GRC components of a historic building regained their original performance, with service life extended by 30 years. Qinglong GRC professional renovation gives buildings a new lease on life.

Inspection and Assessment Techniques

Non-destructive testing to understand the current condition; sampling tests for accurate assessment; calculation and analysis to determine the scheme; risk assessment to ensure safety. Comprehensive assessment is the foundation.

Scheme Design Principles

Economical and rational to control costs; technically feasible to guarantee results; convenient construction to reduce disruption; aesthetically harmonious to preserve character. Scientific design is the key.

Key Points of Construction Organization

Protect the existing structure to avoid damage; phased construction to minimize impact; safety measures to prevent accidents; quality control to ensure results. Careful construction is the guarantee.
