Steel sheet piles are an option for fast execution of retaining wall enclosures for excavations deeper than 3m. The Larssen-type interlock system allows the wall to be rigidly tightened and at the same time waterproof at around 98%. Special sealing solutions can be used for 100% waterproofing.

With a strutting system in place, the excavation quotas can reach up to 20m in depth, with an open excavation.

Apart from the speed of installing the steel sheet piles, a great benefit is the possibility of extraction and reuse.

In non-cohesive soils where the level of groundwater is close to the level of the natural land, the steel sheet piles are the most practical option from the economic point of view and considering speed of execution. The retaining sheet pile enclosures are often equipped with wellpoint systems for dewatering.

Steel Sheet Piles are structural elements typically used in geotechnical works, as retention walls. They replace Diaphragm Walls and Secant / Tangent Pilots and they are installed much faster and in many cases at a lower cost.
Diaphragm walls are subsurface reinforced concrete structures formed and cast in slurry trenches. Excavation is accomplished by digging panels along temporary guide walls using a mechanical or hydraulic clam shell attached to a rig or crane.
We execute concrete piles for ground improvement under the foundation and for retaining walls, having the following technologies: CFA – Continuous Flight Auger, CFA with Vibrated Casing, Screw Piles, Micropiles, Precast Concrete Piles.
Stone Columns installation is a convenient method for improvement of soft ground. Stone Columns are used to improve the infrastructure of roads, railways and buildings. We work with two technologies: Vibroflot Stone Columns, Geotextile Encased Stone Columns (Ringtrac®).
Dewatering Systems are installations that allow excavating and constructing foundations below groundwater level, thus enabling dry work surfaces. Our company performs several types of dewatering works.
We can install: Concrete Bulb Anchors, Duckbill Anchors (Metal Anchor), Tie-rods. Concrete Bulb Anchors are used to support retaining and support walls. Duckbill Anchors are used both for permanent and temporary cases.
Rigid inclusions are an economically advantageous form of land improvement. There are unreinforced concrete columns, installed to take vertical loads. Our teams can install Rigid Inclusions by vibration, using the Silent Piling method or using a drilling rig.
