[Construction Example] Bag Manufacturing Factory: Floor Slab Settlement Correction Work and Underfloor Void Filling Work

basic information

■ What is the Upcon Method? The Upcon method involves drilling small holes with a diameter of 16mm into existing concrete floors that have experienced subsidence, unevenness, tilting, or gaps. While continuously monitoring the level in millimeter increments, polyurethane resin is injected. The resin injected beneath the floor expands rapidly under pressure, compacting and strengthening the ground, improving bearing capacity, and lifting the concrete to correct it. The final strength of the resin is achieved in about 60 minutes. Additionally, if gaps have formed beneath the floor, they can be filled using the same method. *The polyurethane can lift the floor with a foaming pressure of up to 10 tons per square meter, eliminating the need to move heavy equipment or loads. ■ Features of the Upcon Method 1. Short construction period: The construction time is one-tenth that of conventional methods. 2. No interruption of operations: There is no need to move machinery or loads. 3. Comprehensive high technical capability: Responsible construction by 100% in-house staff. 4. Compact construction system: Quick restoration to the original condition is possible. 5. Reduced risk of re-subsidence compared to conventional methods. We provide total support, including on-site surveys, repair planning, and construction, with our in-house staff taking full responsibility. Our specially trained and experienced staff will propose the optimal repair plan tailored to your site.
