Over the last decade HT Costruzioni S.r.l has acquired expertise in the field of structural restoration and strengthening, ranging from conservative redevelopment to seismic conformation, of which the most important example, but not the only one in terms of applied technology, is the work that was carried out on the Pederobba plant kiln tower owned by Giovanni Cementi Rossi S.p.A.

This work saw the implementation of strengthening systems of the beton-plaquè type, with FRP sheets and carbon fiber. The work, completed in 2005, allowed HT Costruzioni S.r.l to acquire a wealth of important knowledge in this field, partly as a result of direct collaboration with the SIKA company, a supplier of products and of the polymerization of resins for bonding and also thanks to distinguished professionals ( P.Eng. Guido Camata, P.Eng. Franco Pasquini, P.Eng. Henry Spacone), responsible for design and construction management on an international level.

A paper on this work was presented at the conference organized by the University of Patras, Patras, Greece, held July 16 to 18, 2007 and entitled: “HIGH TEMPERATURE FLEXURAL STRENGTHENING WITH EXTERNALLY BONDED FRP REINFORCEMENT”.

In detail: Conservative restoration of the Buzzi Unicem SpA Augusta plant wharf The ability of HT Costruzioni S.r.l. is certainly highlighted in this particular field of work, carrying out structural improvements to marine structures such as wharves. This is work which in most cases involves reinforced concrete parts exposed to the elements such as pylons, main and secondary beams and slabs. Because of its nature, this type of construction work must have a set of typical industrial characteristics, standardized as much as possible and with great attention paid to the predictive aspects. Particular attention must be paid to the organization of supplies and handling of materials and equipment necessary for processing, due to the unique environmental conditions.  In this particular sector of operations, Buzzi Unicem SpA has commissioned HT Costruzioni with the structural restoration of the concrete parts of the wharf in Augusta.

The work, which began last April, is expected to take three years and has been planned and will be carried out according to the development policy for serial sub-sites.
