Driven Poles

Made without removing the soil by using a steel tube with a lidding bottom, infused into the ground by a diesel or hydraulic bucket. Particularly used in inconsistent soils, ensuring an improvement in their mechanical properties

CFA and Secant Poles

The CFA (Continue Flight Auger) pole is based on the use of a continuous welded propeller on a hollow shaft which, after drilling, when the soil is disassembled with a tool, receives the material excavated on the slopes of the propeller and transports it to the surface by compacting it simultaneously to the excavation walls. Main feature of piles with C.F.A. is the absence of stabilizing sludge or coating form tubes as well as the drastic reduction in the amount of extracted soil that rises along the propeller to the outside

Large Diameter Bored Poles fromF400 toF3000 mm

Rotation, dry or in the presence of stabilizing sludge, with soil removal using appropriate excavating tools (buckets or carotakers). The excavation is subsequently followed by the laying of reinforcement cages and concrete casting using jet pipes

Nails

“Soil-nailing technique, for the support of excavation faces or slopes under safety conditions, is very useful and advantageous for urban environments with a high environmental value where traditional support works do not can be used.
The ground nailing uses passive reinforcement elements, namely nails (nail), which are installed in the ground, cemented or in direct contact with the ground, with a somewhat reduced spacing; The nails are then connected by means of netting or coatings, which do not bear the sole function of conferring continuity in the distribution of the forces and to protect the face from the surface erosion.”

Vertical Drainage

Performed to reduce consolidation times in low permeable soils, accelerating the ejection of the water by drastically modifying the drainage path. Used in fine grain soil such as inorganic clay, compressible limes, and bags

Geognostic Surveyes

The geognostic surveys are intended to provide the necessary data and information for the geotechnical characterization of the soils and their correct interpretation. They represent the pre-design phase, precisely defining the geological model.

Microplies

They are defined as micropiles when the drilling diameter does not exceed 300 mm. Rotated or rotogravure in soil of any nature and consistency, they are used in containment works (Berlin), underfloor works. The armor is made up of a tubular steel (valves or not) while the injection can be gravity (using cement mortar) or pressure (cementitious cement with appropriate ratio a / c) using double shutter through the valves present In the reinforcing tube.
