PILE FOUNDATION – NEED AND FUNCTIONS

Pile foundation is required when the soil bearing capacity is not sufficient for the structure to withstand. This is due to the soil condition or the order of bottom layers, type of loads on foundations, conditions at site and operational ...

DETERMINING DEPTH OF FOUNDATION

Many factors affects the determination of depth of foundation. Calculation for foundation depth is done based on type of soil, ground water table, loads from structure, bearing capacity of soil and other factors. General factors to be considered for determining depth ...

PILE LOAD CAPACITY CALCULATION

Pile load capacity calculation is done to find the ultimate load the pile foundation can support when loaded. It is also known as the bearing capacity of piles. Pile load capacity calculation is done for single pile or a group ...

CONTINUOUS FLIGHT AUGER (CFA) PILES

Continuous Flight Auger (CFA) Piles are also known as augercast piles, augered cast-in-place piles (ACIP), auger-pressure grout piles, drilled displacement piles and screw piles. Continuous flight auger piles is a type of drilled foundation in which the pile is ...

FOUNDATION SELECTION CRITERIA FOR BUILDINGS

Selection criteria for foundation for buildings depend on two factors, i.e. factors related to ground (soil) conditions and factors related to loads from the structure. The performance of foundation is based on interface between the loadings from the structure and ...

LOAD TESTS ON PILES

Load tests on piles are conducted on completion of 28 days after casting of piles. Two types of tests namely initial and routine tests, for each type of loading viz. vertical, horizontal (lateral) pull out, are performed on piles. ...

BALANCED FOOTINGS AND CANTILEVER FOOTINGS

A balanced footing which is also called as strap footings consists of two separate footings connected by a strap beam. Balanced footing is required where the one of the footing has limited space for bearing, or if there is any ...

CAUSES OF FAILURE OF FOUNDATIONS IN BUILDINGS

Causes of Foundation Failure in Buildings Foundation failure can be attributed to several things.   Most commonly foundation failure is caused by the movement of expansive and highly plastic soils beneath different sections of the foundation footings.   This movement can be in ...
