In the beginning of 2016, ESPAC targeted to cover all project sectors in the construction field. Subsequently, ESPAC established a new post tension concrete division specialized in design and execution supervision of post tension slab and beams, operated by a team of well experienced and highly qualified civil engineers and technicians. Post-tensioning is a method of reinforcing (strengthening) concrete with high-strength steel strands, typically referred to as tendons. In many cases, post tensioning allows construction that would otherwise be impossible due to either site constraints or architectural requirements. Post-tensioned concrete construction has occupied a very important position, the reason for this lies on its decisive technical and economic advantages and come to be used in many situations in buildings "The combination of PAC Panels that are light in weight compared to CMU block walls reduces the loading on structural members such as PT slabs, resulting less thickness leading to less overall load on the foundation. By adopting our combined system, a considerable saving will be achieved in all structural elements due to less quantities of concrete and steel required. With PT slabs where drop beams does not exist, PAC panels height will be identical which makes it easier for production and installation and leads to faster construction and shorter cycle for slab and partition walls."
