Dry-suction techniques are an alternative to traditional excavation. They use air as a means to excavate, remove and suck any type of solid, fluid, or muddy material in both industrial and civil environments.
These techniques have been already adopted in many European countries and in Italy the technique has been consolidating in recent years. However, in Italy there is no regulation on the use and characteristics of these solutions. Gerotto Federico S.r.l. was among the pioneering companies of these technologies in Italy, thanks to suction excavators, the company choses to be among the promoters and among the extenders of the practice under ‘Low environmental impact underground infrastructure technology – Dry-suction systems’ (UNI / Pdr 97: 2020) requirements. The document – published at the end of 2020 – has involved UNI, IATT (Italian Association of Trenchless Technology), UNINDUSTRIA and some Italian players in the sector.
“We are honoured,” commented Alessandro Gerotto, Special Attorney of the Gerotto company, “to be among those who contributed to writing a fundamental document for the innovation of the construction, reclamation and underground utilities sectors. The applications of this technology are numerous and contribute to create a new culture in our sector centred on three key words: technology, safety and sustainability. These techniques have an enormous potential in Italy. In France and England, they are already in tender specifications for intervention in historic centres. To date, Italy has lacked a document that would regulate everything, and we are proud that, thanks to this practice, we have taken a step forward.”
The practice defines the different phases of the dry-suction techniques, it recognises the enormous importance of trenchless technologies in reducing socio-environmental inconveniences compared to traditional excavation techniques, in improving site logistics and in promoting the great flexibility of use of dry-suction techniques in the most disparate industrial sectors, such as steel mills, refineries, chemical and petrochemical plants, glass industries, construction sites, water treatment plants, biogas production plants and much more.
The project has been coordinated by Gianmario Giurlani of IATT: “The pneumatic suction option is now added to the wide field of No-Dig technologies. The working group, together with UNI, IATT and Unindustria, has worked for almost two years and I believe that the result will spread knowledge on non-invasive excavation techniques. We are also working on a draft document that completes the one already written, and it will be about robots for confined spaces and Non-Man Entry situations.” The practice document is available on the UNI Website: UNI/PdR 97:2020
