Foundation Specialists, inc. pioneering in the field of foundation engineering, has introduced new foundation methods.
BORED PILES
are cast-in-place piles ranging from 600mm to 5000mm in diameter and depth of up to 80 meters. They are most suitable as foundation for bridges , high-rise buildings, flyovers, industrial tanks, and other heavy structures. Bored piles are installed by first removing the soil using special drilling technologies then constructing the pile by placing reinforcement and concrete into the hole.
DIAPHRAGM WALL
may be described as an artificial membrane of finite thickness and depth constructed in the ground by means of a process of trenching with the aid of a fluid support.
BARRETTE PILES
are rectangular piles carried out under static bentonite suspension or other fluid support. They have been tested worldwide for foundations of high-rise buildings, bridges, flyovers, and are highly reliable as an efficient method of supporting heavy structures.
CAST-IN-PLACE DRIVEN PILE
CONTINUOUS-FLIGHT AUGER PILE
or CFA pile is constructed using a hollow-shafted continuous-flight auger with diameter varying from 300mm to 650mm and depths of up to 30 meters.
H-PILE
are driven piles using structural steel wide-flanges driven to refusal by diesel or hydraulic hammer.
MICROPILES
are piles of diameter generally smaller than 30cm. executed with special technologies. Many times, micropile installation is chosen due to the limitation imposed by extremely small working space and difficult working conditions.
FS SOILCEMENT COLUMNS
a consolidation system perfectioned by FS, is used to increase the mechanical characteristics, shear, and compressive strength of very poor and water-saturated soil formations where very low bearing capacity is coupled with extremely high liquefaction potential in earthquake conditions. They are also applied to form retaining walls to protect excavation in areas where the high water table and unstable soil do not permit unprotected excavation. In this case, FS Composite Soilcement Coulumns are used.
DRAINS
A relatively inexpensive yet effective method to improve poor foundation soil in advance of construction of permanent facilities is using preloading. The concept of sand blankets, sand drains, and paper drains is to provide shorter drainage paths of excess soil pressure once the preload is placed.

FS SOIL & ROCK ANCHOR
are straight elements integrated into the soil consisting of steel reinforcement (strands) of high yield strength grouted to the surrounding soil. They are largely used in tying back retaining structures, holding down structures subjected to uplift forces, and ensuring stability of natural and artificial rock slopes.
SOIL NAILING
are often used to hold shotcrete or gunite on the face of slopes.

SPECIAL FOUNDATIONS

BACK TO TOP
is a special type of pile developed for almost all types of soil. Its construction utilizes a closed-bottom temporary casing driven by a diesel or hydraulic hammer. Upon installation of the reinforcement and concrete, the temporary casing is extracted by a vibratory device leaving a continuous, well-compacted pile.
FS SOIL & ROCK ANCHOR
are straight elements integrated into the soil consisting of steel reinforcement (strands) of high yield strength grouted to the surrounding soil. They are largely used in tying back retaining structures, holding down structures subjected to uplift forces, and ensuring stability of natural and artificial rock slopes.
ALIGNED-PILES WALL SYSTEM
An original design of Foundation Specialists, inc. to install walls in sensitive areas, the Aligned-Piles Wall System is a n alternate workable solution in retaining soil for deep excavation.
