Specific analysis of detoriation its cause and rate are very important from point of deciding repair system to be adopted for projects for its suitability and durability.
Sanrachana has inhouse trained corrosion engineers to use and access various high-tech equipment’s and systems for studying corrosion in the structure; with the help of these equipment we can easily map corrosion potential contours and pinpoint the exact areas-corrosion hot spots that require due attention.
Depending on the existing corrosion rate and expected service life of the structure, sanrachana helps in designing precise corrosion mitigation strategy that suits client’s requirements.
These are bipolar corrosion inhibitors; due to its affinity for steel and high vapour pressure it passes through concrete and protects the embedded steel from corrosion at both cathodic and anodic ends.
MCI helps in protection of steel rebars from corrosion thereby extending service life and are available in two forms, surface applied liquid form as well as drill insert and embed type sustained release caplet.
In RCC elements already applied with surface protective coating liquid MCI are injected under pressure through nozzles at specific intervals.
Sacrificial galvanic anodes are part of cathodic protection (CP) system used to protect embedded steel from corrosion, made with metal alloy having more “active” voltage than steel rebars it protects steel by sacrificing itself in preference to the steel when applied properly as per design.
Spacing is decided based on type of structure, existing rate of corrosion, the resistivity of the base material concrete and the service life required.
Sanrachana provides pile repair services with use of prefabricated FRP jacket for piles affected by erosion or corrosion . These jackets are fixed to piles around the area of damage and the annular space is filled with under water micro concrete or epoxy grout through prefixed inlet ports available on jacket. Excessively damaged steel is replaced by underwater divers and CP systems are fixed for additional durability. FRP jacket with internal anchor holds becomes an part of the new member thereby protecting the repaired pile element from direct attack of erosive as well as corrosive force
Sanrachana works with various coatings such as rust converters, zinc rich and epoxy paints, corrosion inhibitors, hot and cold galvanizing, epoxy phenolic coatings, CPCC, concrete surface applied acid and alkali resistant hi build coatings, etc towards protecting of steel, rebars and concrete elements from process and environmental damages.
