Structural strengthening
Structural Strengthening
Structural strengthening is used for upgrading structures to increase performance and strength of structural members to help carry intended and/or additional loads. The need for structural strengthening is usually dictated by building codes, change in building use, deterioration or degradation, and deficiencies caused by design and/or construction errors.
Our Services Include:
- Beams, Columns, Walls, Slabs
- Axial Load Enhancement
- Seismic Retrofits
- Carbon Fiber Strengthening
- Corroded Steel Members
- Aged, Rotted, Substandard Wood Framing
Revolution Mill
Existing conditions consist of a six-story facility constructed with brick masonry exterior walls and reinforced concrete floor framing. The first floor was elevated likely due to the flood plain from the adjacent creek. The underlying concrete floor components exhibited distress resulting in spall defects. Our team repaired overhead and vertical concrete spalls, beams, and columns.
Repair steps involve saw cutting to define the repair area, chipping and removing any loose defective substrate, sand blasting the concrete and any remaining reinforcing surfaces, applying a bonding agent, followed by patching with repair mortar. Hand packing and forming and placing procedures were used. There were 148 CF of beams, 200 CF of columns and 2 carbon fiber wraps involved in this project.
