We help you overcome deterioration in structures due to
- Corrosion of steel
- Environmental Effects
- Poor Quality construction practices
- Poor Quality Supervision
- Design flaws
- Spalling of concrete cover, Swelling of concrete due to Alkali Aggregate reaction (AAR), Cracks parallel to the reinforcement, Spalling at edges, Dislocation, Internal cracking and reduction in area of steel reinforcement
- Freezing & thawing, Thermal effects, Shrinkage stresses
- High porosity
- Improper choice of cement type for the conditions of exposure
- Inadequate curing
- Exposure of structural element to alternate cycles of wetting and drying
- Chemical attack on concrete like a) Acid attack b) Alkali attack c) Carbonation d) Chloride attack e) Leaching f) Salt attack g) Sulphate attack
- Biofouling in concrete - Unwanted growth of microorganisms, plants, algae, or animals on wet surfaces of concrete structures
- materials
- Effluents from industries
- Inorganic acids
- Shrinkage & Creep etc.
