Specialized Systems for Structural Strengthening of Structures

The need for increasing or restoring the structural capacity of structures is commonly driven by design code changes, cases of seismic retrofit, extending a building or changes in use, modification of the structure due to errors in design or construction or loss of capacity due to aging or deterioration of construction materials.
CTech-LLC®’s structural strengthening solutions are engineered to enhance the structural capacity of existing structural elements by solving a host of structural deficiencies or demands. This is achieved using a wide range of systems based on FRP composite, FRCM composite, post-tensioning, section enlargement and hybrid rehabilitation method.
CTech-LLC®’s structural strengthening systems can be used as a proven solution to bring commercial, municipal, residential and even historical buildings up to a safe standard.
CTech-LLC® structural strengthening solutions have been used extensively on vital transportation infrastructure including bridges, tunnels, elevated roadways, airports to regain the original capacity of damaged structures.
CTech-LLC® structural strengthening systems are ideal for enhancing the structural capacity of oil & gas & industrial facilities which require additional strengthening, rehabilitation, and repair.
CTech-LLC® structural strengthening systems are installed in marine environments (e.g. ports, wharves, piers, jetties etc.) for protecting structural elements and extend the life of the marine structures.
