DEEP FOUNDATION PILING
Prefabricated steel, wood or concrete piles are driven into the ground using impact hammers.
This type of pile installation is used to replace soil removed by drilling …
This method combines all major piling operations in a single process …
Pile caps connect groups of piles to distribute loads over the capped piles.
The variables, unknowns and constraints involved in retaining wall design are many, making it a complex and challenging task. A retaining wall design has to account for a number of factors, foremost being the stability of the wall itself. A thorough analysis of the...read more

RETAINING WALLS (SHORING)
Closely spaced piles used to form retaining walls in areas where water inflows are not significant.
Secant (tangent) piles are interlocking piles that form a continuous watertight wall.
Sheet pile walls are constructed by driving prefabricated reusable panels into the ground.
Diaphragm walls are formed from cast-in-place reinforced concrete panels with interlocking vertical joints that provide a continuous watertight barrier.
The main purpose of soil nailing is to construct a retaining wall or reinforce, strengthen and thus stabilize ground slopes providing a cost-effective retaining system for a variety of ground conditions.
Tiebacks may be used to avoid overstress due to large cantilever lengths.
In situations where anchors cannot be used or only temporary retaining wall support is required, or for other reasons, struts are used to provide such support during excavation.
Soldier piles, are steel wide flange H-beam piles spaced 1 to 3 meters apart.
