Building Rehabilitation works:
Strengthening of RCC structures
Strengthening of columns for enhancing load carrying capacities strengthening beams enhanced flexure and shear strengths strengthening of slabs, retaining walls etc.
- Seismic retrofitting of RCC structures
- Repairs and restoration of RCC structures
- Reinforcement of beams
- Glass and carbon fiber wrapping
- Improvement of impact resistance and blast resistance properties
Column strengthening Using Carbon Fiber
Strengthening of columns using Carbon fiber wrapping using single and double layers as per design given by consultant to enhance the load bearing capacity.
Column Strengthening Using Ms Plates
Columns were retrofitted to achieve the strength required as per design using steel plates.
Beam Strengthening Using Carbon Fiber
Strengthening of beams using carbon fiber to increase flexural strength.
Slab Strengthening Structural Screed Works
The client requirement was to enhance the load bearing capacity of the slab.
Slab Strengthening by Micro-Concrete
In this slab, all the unsound and flaccid concrete was removed and filled with free flow micro-concrete of higher strength.
Repair of Concrete Spalling and Carbonation
Spalling concrete refers to the phenomenon of surface patches of concrete breaking up and delaminating in the absence of immediate external influences such as accidental impact loads or fires.
Spalling may be caused by several factors, including:
(a) Corrosion of rebars, the process of which results in the steel bars expanding and forcing the concrete apart.
(b) Sulphate attack on concrete.
(c) Alkali-silica reaction.
(d) Freeze-thaw cycles.
Fresh concrete is highly alkaline with a pH of about 12. This alkalinity provides passivation protection to the steel rebars and wards off corrosion. However, over a passage of time, the alkalinity drops and when it reaches a pH value of about 9 or less, the passivation protection is destroyed.
