We are a Civil Engineering firm specialized in Structural Repairs and Rehabilitation of RCC structures. Old RCC Structures requires continuous maintenance in the form of retrofitting of buildings and structural repairs. Rehabilitation of Structures in the form of polymer mortar, micro concreting jacketing, normal concrete jacketing, Fibre wrapping and epoxy mortar.
Repairs & Rehabilitation is an skillful engineering, wherein clear understanding of the behavior of the structure is important.
We provide the following services for Structural Repairs.
Spray Polymer
This technique is a ready-to-use sprayable – cement based repair mortar, giving high early strength, reduced rebound and allows for thickness upto 150mm in one go. This polymer based mortar is to be pressure sprayed ,with addition of required amount of water and no in-situ addition of any other material. The repair work is speedy and the set mortar attains strength upto 40N/mm² in 28 Days.
USES: Reinstating of columns, cement silos and chimneys, retaining walls, water front structures, dams, irrigation canals, tunnel linings etc.
Carbon Fiber Wrapping
Carbon Fiber Wrapping improves the Load Carrying Capacity of structural members. It is easy to install for any shape and size of a structural member. It gives strength very quickly with least disturbance to the existing structure. It increases the lifespan of a structure. Carbon wrapping does not change the shape of the existing structure.
Glass Fiber Wrapping
Glass Fiber Wrapping is done to improve the strength of RCC Members, Masonry, etc. Using this method the resistance to seismic movements can be improved. It is light in weight and can be used where the size of the member cannot be changed while retrofitting.It is a cost effective repair alternative when compared with other methods.
Carbon Laminate
This method uses strips of carbon laminate. This externally bonded strip is analogous to steel plate bonding, but since it is light in weight, it does not add any dead weight to the structure. One of the advantages of Carbon Laminates is that they do not corrode or rust.
Micro Concrete Jacketing
Micro concrete is the ready to use, self flowable mixture generally made under strict quality control in automated factories.
Advantage
. Attains high early and ultimate strength
. It’s gaseous expansion qualities compensates for shrinkage and settlement in the plastic stage.
Polymer Modified Mortar
Where concrete structures have deteriorated due to corrosion and where changes in use and/or design code do not demand increase in loading capacity, Efficient repairing of concrete structures can be done by application of POLYMER MODIFIED MORTARS.
Epoxy Mortar
A three-component, water-washable 100% solids epoxy mortar system for installations where exceptional high-strength and chemical and impact resistance is required. 100% solids epoxy systems unique formula produces a mortar with greater bond and compressive strengths and improved chemical resistance over conventional cement or emulsion-based setting systems. Use for epoxy mortar patching and overlays on interior, horizontal substrates.
Sacrificial Anode
The principle of cathodic protection is in connecting an external anode to the material to be protected from corrosion and passing of an electrical DC current. So that all area of the metal surface become cathodic and therefore do not corrode. The external anode may be a galvanic ( sacrificial ) anode or it may be an impressed current anode where the current is impressed from external D.C source.Three metals that can be used as sacrificial anodes are zinc, aluminium, and magnesium.
