DIAPHRAGM WALLS

Diaphragm walls are subsurface reinforced concrete structures formed and cast in slurry trenches.

✔ 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, and then connecting the panels to form continuous walls.

✔ Bentonite or polymer based slurries are used during construction to prevent soil incursions into the trenches. Reinforced cages are placed followed by structural concrete.

✔ The result is a structural wall system that not only provides temporary earth support and a groundwater barrier, but also provides the permanent foundation system, being load-bearing.

STEEL SHEET PILES

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.

STONE COLUMNS

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®).

CONCRETE PILES

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.

RIGID INCLUSIONS

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.

ANCHORS

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.

DEWATERING SYSTEMS

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.
