Bored Pile using Bentonite System Also called drilled piers or Cast-in-drilled-hole piles (CIDH piles) or Cast-in-Situ piles. 
Rotary boring techniques offer larger diameter piles than any other piling method and permit
pile construction through particularly dense or hard strata using auger, bucket and core barrels.

Micropiles are also known as minipiles, pin piles, needle piles, and root piles. The micropile casing generally has a diameter in the range of 3 to 10 inches. Typically, the casing is advanced to the design depth using a drilling technique. Reinforcing steel, typically an all-thread bar, is inserted into the micropile casing. High-strength cement grout is then pumped into the casing. The casing may extend to the full depth or end above the bond zone with the reinforcing bar extending to the full depth. The finished micropile (minipile) resists compressive, uplift/tension, and lateral loads and is typically load tested in accordance with ASTM D 1143 (compressive), ASTM D 3689 (uplift/tension), and ASTM D 3966 (lateral). Capacities vary depending on the micropile size and subsurface profile. Allowable micropile compressive capacities of more than 500 tons have been achieved. 

Shoring Works
Shoring work is a guide wall usually constructed to hold the cage and guide the excavation operation. Secant or Contiguous Pile wall in general may be constructed as temporary shoring structures or as permanent part of the otherwise adjacent structure. The excavation can be done by drilling machine. Drilling operation is usually carried out under fluid support.

Secant Pile
Secant pile walls are formed by constructing intersecting reinforced concrete piles. The piles are enforced with either steel rebar or with steel beams and are constructed by either drilling under mud or auguring.
Contiguous Pile
Typically this technique is suitable to retain stiff and cohesive sub soils and where ground water levels are below the eventual depth of excavation. Pile diameters range between 450mm and 900mm and are generally installed at pile centers of between 500 and 1000mm respectively thereby leaving gaps between the piles between 15 and 100mm.
Soldier Pile
Soldier piles, also known as king piles or Berlin walls, are constructed of wide flange steel H section spaced about 2 - 3 m apart and are driven prior to excavation. As the excavation proceeds, horizontal timber sheeting (lagging) is inserted behind the H pile flanges.


Hbeams W/ Steel Panel & Hbeams W/ Wood Sheets

known also as Berlin Method, because it was originally used for the Berlin subway prior to the Second World War. The use of Berlin Method should be limited to shallow excavation in relatively dry or dewatered soils. The soldier piles may be driven or installed in a predrilled borehole.



Tiebacks are small diameter drilled elements consisting of steel strands or thread bar members grouted into place and tensioned to provide a preloaded condition
 to the underlying soil.


Cutting Head of Pile

The breaking down of concrete piles is an essential part of the construction process and a subject that is often not given sufficient early thought in the planning of the work. The adoption of a suitable pile breaking method can result in financial and programmable savings and most importantly will address and reduce potential health and safety issues in relation to this                                          phase of work.



Deep Well Watering
It is removal of water from solid material or soil by wet classification, centrifugation, filtration or similar solid liquid separation processes. Removing or draining water from a riverbed, construction site, caisson, or mine shaft, by pumping or evaporation 

Well Point Watering
These systems are beneficial for dewatering to depths at which suction lift limitations prevent the use of well point pumps. Deep wells also offer the ability to control large volumes of water.

Pile Testing
Pile Static Load Test

Static Load tests are performed during the test phase of each contract to verify the design assumptions and load-carrying capacity of the pile 

Pile Integrity Test
The Pile Integrity test (PIT) is used for bored piles, driven concrete shafts, concrete filled piles or drilled shafts. It detects potentially dangerous defects such as major cracks, necking, soil inclusions or voids.

Stone Column

Stone Column is a ground improvement technique used to improve the load bearing capacity and reduce the settlement of the soil. It is also called as granular columns or granular piles. This technique is also known as vibro replacement. In this technique dense aggregate column (stone columns) is constructed by means of a crane-suspended downhole vibrator.
