Strengthening of PT Floor for a commercial IT building
- The PT concrete flat slab showed major cracks for an important commercial IT building.
- Misplaced PT cables were found as a prime reason for those cracks on two floors.
- Floor load was partially relieved by proppingup the entire floor area from below.
- Cracks were sealed from below and grouted with monomer from top under gravity.
- A system of FRP laminate was designed and applied on top of slab to counter the deficiency
- Sanrachana successfully carried out retrofit of around 1 lakh sqft area using 10000 Rmt of carbon fiber laminate.
- Full scale load test was successfully carried out by using water load before handling over to client.
- Entire project was completed in 60 days.
