Technologies

Micropiles

Micropiles allow solving some problems concerning the execution of foundations thanks to the possibility of using equipment having reduced sizes and encumbrance...

Compaction Grouting

The technology known in the technical literature as compaction grouting is a solution aimed at compacting and amassing soft or altered, decompressed soil...

Dynamic Compaction (Heavy Tamping)

Dynamic Compaction is a ground modification technique whereby loose soils can be effectively and economically densified to improve its mechanical characteristics and allow...

Artificial Ground Freezing

Ground freezing consists in freezing the water contained in the soil pores until turning it into ice.

The CAP (Cased Auger Piles) technology consists in drilling separate piles by means of a continuous flight auger coaxial with an external casing. The same technique can also be used to drill secant piles; in this case it is named CSP (Cased Secant Piles).

Diaphragm Walls – Hydromill

The excavation of diaphragm walls with hydromill allows the construction of panels with max deviation from the vertical of about 0.3÷0.5%, at dephts beyond 200 m.

Slurry Walls

A slurry wall is a system that can provide lateral retention, load bearing capacity and waterproofing to a foundation while becoming part of the permanent structure.

Sand and Wick Drains

When loads are to be applied to saturated compressible soils, pre-consolidation ot the soils to prevent excessive differential settlements by means of drains is usually required.

Dynamic Replacement

Dynamic Replacement is an extension of Dynamic Compaction to compressible soils where large diameter columns are constructed by dropping heavy pounders from great heights onto the soft soil.

Rigid Inclusions

In general, the word "inclusions"means a type of consolidation that improves the strength of a soil mass through the inclusion

Cement and chemical Grouting

Injection technique is used in civil engineering to improve the mechanical and permeability properties of soil, rocks and brick or concrete work.

Deep Soil Mixing

This system, with the addition of dry powdered cement binder, requires soil with a high water content, which allows the setting reaction of the binder to completely develop.

Jet Grouting

Jet grouting improves soil mechanical and permeability properties by using high-speed jets of fluid to break up and loosen soil and mix it with a cement grout.

Sheet pile and Combi Walls

Sheet piling is a technology widespread in various engineering fields. This is an advantageous solution for supporting excavations, bank protection and in river bed works, just to mention a few of the many possible applications.

Displacement Piles

If soil removal has to be minimized during foundation works, displacement piles can be the solution.

Driven Piles

Driven piles are cast in situ without soil removal. In this sector, Trevi's most prestigious product is VIBROTREVI, which is performed by driving a casing closed at its bottom.

CFA Piles

The piles realized using the Trelicon technology have the advantages of driven piles and the application versatility of bored piles.

Large Diameter Bored Piles

Bored pile technology dates back to the beginning of the last century. Nowadays, with increasingly powerful equipment available this technology can be used to construct foundation piles up to 4 m in diameter and 100 m deep.

Directional Drilling

The TDDT system stems from the HDD (Horizontal Directional Drilling) technologies used to lay utilities (usually cables and pipes) underneath surface obstacles (watercourses, roads, railways, structures, buildings, etc.).

Ground and Rock Anchors

Tie rods are structural elements undergoing traction and suitable for conveying loads to soil depths.

Vibroflotation

Vibroflotation or vibrocompaction consists in the re-organization of soil particles until reaching a denser configuration by means of powerful vibrators.

Vibroreplacement

Deep vibro techniques offer flexible solutions for soil improvement. They are mainly used to improve the bearing capacity, reduce settlements under structural foundations and eliminate liquefaction potential.
