What Are the Steps of GRC Installation? Detailed Explanation of the Standardized GRC Installation Process

GRC installation must follow a standardized process, generally divided into six stages: preparation work, surveying and setting out, substrate treatment, panel installation, joint treatment, and cleaning and acceptance. Each stage has strict technical requirements.

In the Shanghai Century Plaza renovation project, the Qinglong installation team strictly implemented the standardized process: first, on-site surveys were conducted using a 3D scanner to obtain substrate data; then a BIM model was used for installation simulation to optimize the installation sequence; during installation, a bottom-to-top, middle-to-sides sequence was adopted, completing a fixed area each day; joint treatment used a special sealant applied in two passes; finally, a comprehensive inspection and acceptance was carried out. This standardized operation ensured the project was completed to a high quality.

Pre-Installation Preparation Stage

Verify drawings against on-site dimensions; adjust if deviations exceed tolerance. Check panel numbering, quantity, and quality, and replace damaged panels. Prepare construction tools and check safety devices. Technical briefings clarify key points.

Surveying and Setting Out

Set installation datum lines with a precision of ±1mm. Mark panel layout lines clearly and accurately. Re-check substrate dimensions and record deviation data. After setting out, re-verification is required for confirmation.

Substrate Treatment Requirements

Substrate strength must meet standards, free of hollowing and cracking. Flatness deviation ≤4mm/2m. Waterproofing layer intact, with no leakage. Embedded parts positioned accurately, firm and reliable.

Panel Installation Technique

Install in numbered sequence to prevent mix-ups. Hangers must be fixed firmly and adjusted into position. Panel joints should be even with consistent width. Inspect and correct promptly to ensure quality.

Strictly following the standard process is the guarantee of installation quality. Qinglong GRC's standardized installation system ensures every project is presented perfectly.
