Along with aesthetic looks and finish, we are known amongst various industries for the high quality of concrete we use in our state-of-the-art facility. There are numerous advantages of Precast Concrete over Cast-in-situ processes. Pre Stressed: Pre-stressing is a method in which compression force is applied to the reinforced concrete section.  The effect of pre stressing is to reduce the tensile stress in the section to the point till the tensile stress is below the cracking stress. Thus the concrete does not crack.  It is then possible to treat concrete as a elastic material.  There are two basic methods of applying pre-stress to a concrete member  Pre-tensioning – most often used in factory situations  Post-tensioning – site use.
