The CAP (Cased Auger Piles) technology consists in drilling separate piles by means of a continuous flight auger coaxial to an external casing. The same technique can also be used to drill secant piles; in this case it is named CSP (Cased Secant Piles).
Sheet piling is a technology widespread in various engineering fields. This is an advantageous solution for supporting excavations, protection of side walls and in river bed works, just to mention a few of the many possible applications.
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 (water streams, roads, railways, structures, buildings, etc.).
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.
