Prefabricated concrete piles are poured, cured and stored in a yard, mostly by driving, before being installed on the farm.

Advantages of Precast Concrete Piles

The reinforcement used in the pile is not liable to shift or be disturbed
Defects in piles can be easily identified after removal of forms, and these defects (such as the presence of cavities or holes) can be repaired before the pile is run.
The cost of construction will be less, as multiple piles are constructed at a time.
Precast concrete piles can be run under water. If groundwater contains more sulfates, the concrete set of cast in situ piles will not. Thus the pile of precast concrete has added advantage in such a situation.
Precast concrete piles are highly resistant to the biological and chemical actions of the sub soil.
Better quality control can be implemented than bore cast in situ piles.
These piles can be constructed in various cross-sectional shapes such as circular, octagonal or square.

Disadvantages of Precast Concrete Piles

These piles are usually very heavy. Therefore special equipment is required for handling and transportation.
Adequate care must be taken at the time of transportation, otherwise the piles may break.
Heavy pile driving equipment is required to apply these piles in the field.
These piles are expensive as additional reinforcement is required to bear the handling and driving stress.
The length of the pile is restricted as it depends on the transport facility.
Once constructed, it is not possible to increase the length of the pile (as per the demand of the site)
If the pile is found to be too long, during driving, it is difficult and unconstitutional to cut it. Cutting off the extra length also leads to wastage of material.
Running these piles caused a lot of noise pollution.
