The flatness, drainage slope, and thickness uniformity of concrete drainage boards directly affect drainage efficiency and structural safety. Using the HOLON3D handheld full-blue laser 3D scanner, you can quickly capture complete 3D data, compare it with the original model, and generate color maps to accurately quantify overall deformation and slope deviations.

Drainage boards are large, with widths of two to three meters. Traditional measuring tools like rulers and feeler gauges can only check a few points, which is inefficient and inaccurate, making it impossible to capture the full surface of the board. The slope of the drainage board and the direction of water flow directly affect drainage performance, but traditional methods can't clearly show the overall height differences or deviation values, making it hard to scientifically determine if the product meets standards.

Our engineers took our HOLON3D handheld industrial 3D scanner to the client's site for scanning. Its handheld design is flexible, not limited by the large size of the drainage panels, allowing us to quickly complete full-panel scans and greatly improve inspection efficiency. The scanned data of the actual drainage panels is precisely aligned with the original 3D model or theoretical slope reference, and a global 3D deviation color map can be generated with one click. The color map intuitively shows the deviation distribution across the panel surfaces with colors like red, yellow, green, and blue—red indicates raised areas (positive deviation), blue indicates depressions (negative deviation), making the overall deformation trend and water flow direction instantly clear. With this solution, we successfully achieved high-precision, high-efficiency 3D inspection of the concrete drainage panels for our client.
