KARACHI (PR) - Pakistan is currently witnessing the emergence of a formidable growth in a real estate development that has crept suddenly into the country as an offshoot to the success in such developments in the region. This was stated by Roland Asaker, Regional Manager, CCL Gulf Prestressed Concrete LLC while giving a presentation on Post-tensioning slab technique, organized by Arabtec Pakistan in collaboration with world renowned CCL Gulf Prestressed Concrete LLC. Post Tensioning is a technique of pre-loading the concrete in a manner which controls stresses and deflections that are induced by the self weight and applied loads, while the structure is in service. Arabtec Pakistan, through a collaboration agreement with CCL, plans to use post tensioning technique in the currently under-construction Karachi Financial Towers, being developed by ENSHAANLC Development in Karachi.
