it-building

Problem: 

  • 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.

Soultion:

  • 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.
