The Company ensures integrated design services while guaranteeing the ideal coordination and interaction of its internal competences.
In addition to a consolidated tradition in the geotechnical field, it can currently boast several design and construction technical assistance services in the following sectors: transportation infrastructure, underground works, marine works, reinforced concrete buildings, hydrogeological and landslide solutions and also reclamation and environmental protection works; special experience has been gained over the last 4 years in nearshore liquefied gas installations and related offshore structures.
In the case of complex projects to be carried out in association with other companies, SOIL srl have often followed the coordinating activities, taking on the responsibility of integrating all subjects and disciplines, including those deemed as “external” to its sector (architectural, functional and plant design issues).


SOIL srl carry out its activities in the following sectors:



  • geotechnical and geomechanical analyses
  • planning and execution of geotechnical investigations resorting to subcontractors on behalf of the Client
  • management of site investigation
  • geotechnical aspects concerning waste disposal and soil remediation
  • geotechnical engineering of railways and roads
  • civil and industrial foundation design
  • special foundations, soil improvement techniques
  • liquefaction and seismic protection analyses
  • dewatering
  • deep excavations
  • validation of projects on behalf of certified companies


  • geological, geomorphological and seismic design, inclusive of survey mapping

Costa Concordia Parbuckling

For the purposes of the safe removal of the Costa Concordia wreck, SOIL Srl has been involved into all aspects concerning the geological and geotechnical design and assistance for the construction of the foundation structures.

The Costa Concordia Wreck Removal Project foresaw in the first stage the rotation of the wreck to its vertical position (parbuckling phase) and subsequently its re-floating by means of the installation of steel caissons on both sides of the ship.

The parbuckling required the construction of underwater anchoring structures on the landward side of wreck and the installation of three submerged platforms for its temporary support in vertical position on the seaward side. The structures were built respectively at water depths of 5 ÷ 10m and 40 ÷ 50m below sea level. Drilled steel piles (D = 2m) were designed for the platforms foundations.
