Growing sophistication and advancement in construction and engineering have given rise to innovations and new techniques in the construction industry, as post-tensioning, which is a technique for reinforcing concrete, reducing the occurrence of shrinkage and cracking by strengthening concrete with high-strength steel strands or bars called tendons, has been innovated to reinforce concrete in construction.
Introduced into the Nigerian construction industry by ITB Nigeria Limited, leader in integrated engineering and construction solutions, post-tensioning technique comes as a unique solution in the global construction industry.
The technique is a form of pre-stressing where the stressing of the tendons is done after pouring and setting of the concrete, thus the name, post- tensioning. It has numerous advantages over standard reinforcing steel as it allows construction that would otherwise be impossible due to either site constraints or architectural requirements to be achievable.
“At ITB, we constantly strive to improve the quality of our work, elevate levels of client satisfaction, and most importantly, contribute significantly to the advancement of the Nigerian construction and engineering community.
“Our introduction and use of the post-tensioning techniques will guarantee premium quality structures, ensure flexibility of layout and servicing, lighter structure, and lesser construction time,” Ramzi Chidiac, managing director, ITB Nigeria Limited, assured in a statement in Lagos at the weekend.
Gabby Haddad, a post- tension expert/civil engineer with ITB Nigeria, affirmed, urging clients and potential homeowners to consider and opt for this technique.
“If we are to grow the construction industry and build structures of world class standards, it is important that we innovate and adopt new technologies.
“We are glad to be the pioneers in Nigeria having deployed the technology since 2003 on the Sapetro Towers project, Victoria Island Lagos. We have other landmark projects across the country and with further improvements in ongoing projects. Post-tensioned slabs tend to have longer life span, concretes are held more tightly and cracks are eliminated,” he explained.
