TECHNIQUES TO RESTORE ORIGINAL STRENGTH OF STRUCTURES

The techniques are described below among with other restoration measures. Small cracks If the cracks are reasonably small (opening width=0.075mm), the technique to restore the original tensile strength of the cracked element is by pressure injection of epoxy. The procedure is as follows. The external surfaces are cleaned of non-structural materials and plastic ports are placed among the surface of the cracks on both sides of the member and are secured in place with an epoxy sealant. The centre to centre spacing of these ports may be approximately equal to the thickness of the element. After the sealant has cured, a low viscosity epoxy resin is injected into one port at a time, beginning at the lowest part of the crack in case it is vertical or at one end of the crack in case it is horizontal. The...

Shoring, Underpinning and Scaffolding

                Shoring is a general term used in construction to describe the process of supporting a structure in order to prevent collapse so that construction can proceed. The phrase can also be used as a noun to refer to the materials used in the process. Underpinning is the process of strengthening and stabilizing the foundation of an existing building or other structure. Scaffolding is a temporary frame used to support people and material in the construction or repair of buildings and other large structures.                      Shoring is used to support...
