About prestressing technology

The structures are prestressed by applying loads that arise when the pre-tensioned reinforcement, trying to contract, transfers pressure to the structure at the anchoring points and at the places where the reinforcement trajectory changes. For all types of structures (reinforced concrete, steel, steel-reinforced concrete, fiber-reinforced concrete, wooden), prestressing allows to save materials and reduce total mass of the structure, and for reinforced concrete structures it improves crack resistance.

The following elements may be prestressed:

  • Girder prestressing
  • Floors prestressing
  • Slabs prestressing
  • Restressing of reinforced concrete structures and individual elements

Where is prestressing of structures used?


Civil construction: parking, shopping centers, office buildings, hotel complexes


Transport construction: bridges, overpasses, crosswalks


Hydraulic engineering construction: riverside wharves, sea offshore platforms


Industrial construction: silos of cement, sugar and other bulk materials


Storage tanks for liquefied gas (LNG), sump tanks for liquids


Construction of nuclear power plants: structural steel of nuclear plants

(Русский) АЭС


(Русский) Система преднапряжения защитной оболочки (СПЗО) на объектах использования атомной энергии (ОИАЭ)

Project Features:

(Русский) Система преднапряжения защитной оболочки (СПЗО) – совокупность горизонтальных и вертикальных арматурных пучков, предназначенная для обжатия внутренней защитной оболочки, в целях восприятия растягивающих усилий, возникающих при действии внутреннего избыточного давления в случае аварии. Таким образом, обеспечивается прочность и трещиностойкость железобетонных сечений оболочки при малых процентах ненапрягаемой арматуры. Внутренняя защитная оболочка (ВЗО) – сооружение из предварительно напряженного железобетона, состоящее из цилиндрической части и полусферического купола. Специалистами АО «Институт технологий преднапряжения» были выполнены комплекты рабочей документации на СПЗО, по следующим объектам:
1. Ленинградская АЭС-2 блок №1;
2. Курская АЭС-2, блоки №1 и №2;
3. АЭС Аккую, блоки №1 и №2;
4. Ростовская АЭС (замена элементов).

      Frequently asked questions

      • Why is it worth approaching your company?

        We are the only organization in CIS that has occupied the specialists in prestressed structures in all areas of construction. Some unique specialists in bridge and nuclear construction work with us.

      • Which construction organizations can build a facility using your projects?

        Any organization that has experience in formwork, reinforcement and monolithic work is able to use our projects to construct on its own. However, specialized prestressing works are usually entrusted to the companies that already have experience working with such projects. In such cases, we recommend our partner STS Ltd. This is a developer, manufacturer and supplier of the Russian prestressing system. This company has its own construction department. Coordination between the construction participants is easy. The experience has proven than no effect on the timing or quality of the object occurred. Of course, it is possible to perform prestressing by the contractor’s efforts according to the installation supervision scheme from a company with experience in prestressing.

      • Do you have experience in passing state expertise?

        Yes, we are proud to say that since 2007 we haven’t had a single negative conclusion of state expertise on our facilities.

      • Is it possible to see a facility with the prestressing system under construction?

        We will be please to do it. Contact us and we will select the most suitable facility for you.

      • How do you control the quality of implementation of your projects?

        We provide field supervision services for construction according to our documentation. We also have implemented a non-conformance management system both for internal comments and for comments from customers.

      • How does communication with the client go?

        First, an inquiry specification is compiled. It is discussed with the Client, Chief Project Engineer (CPE), and Director for Design. Then, the Chief Project Engineer makes the estimated labor intensity and you get a commercial quotation. When the contract is concluded, Chief Project Engineer prepares a design schedule, Director for Design allocates the Team Manager and employees for implementation. While preparing documentation, technical and regulatory control is carried out. After that, Chief Project Engineer sends the documentation to the client and receives feedback from it (comments), sends reports of the work performed.
