Micropiles allow solving some problems concerning the execution of foundations thanks to the possibility of using equipment having reduced sizes and encumbrance...
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 is a ground modification technique whereby loose soils can be effectively and economically densified to improve its mechanical characteristics and allow...
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).
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.
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.
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 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.
In general, the word "inclusions"means a type of consolidation that improves the strength of a soil mass through the inclusion
Injection technique is used in civil engineering to improve the mechanical and permeability properties of soil, rocks and brick or concrete work.
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.
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.
'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.
If soil removal has to be minimized during foundation works, displacement piles can be the solution.
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.
The piles realized using the Trelicon technology have the advantages of driven piles and the application versatility of 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.
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.).
Tie rods are structural elements undergoing traction and suitable for conveying loads to soil depths.
Vibroflotation or vibrocompaction consists in the re-organization of soil particles until reaching a denser configuration by means of powerful vibrators.
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.
