To avoid the formation of expansive cracks as a result of temperature changes As concrete is placed in a confined space, it expands due to the high temperature, resulting in cracks.
Concrete is not an elastic material, so it can not bend or stretch without breaking. Concrete, on the other hand, expands and shrinks, causing structural components to change slightly.
Several expansion joints are used in concrete construction to avoid adverse effects from concrete movement, including floors, walls, roof expansion joints, and paving slabs.
These joints must be engineered, found, and assembled with care. If a slab is continuously placed on surfaces with more than one face, an expansion joint will be required to minimize stresses. A concrete sealer may be used to fill in holes left by cracks.

Borrow pits are a source of danger to the traffic and hence should be avoided as far as possible.
Advantages of precast or readymade piles are the following: Precast piles can be cast well before the starting point of the work resulting in rapid execution of work. Their construction can be well supervised and any defect detected can be rectified before use. the reinforcements remain in their proRead more
Advantages of precast or readymade piles are the following:
Precast piles can be cast well before the starting point of the work resulting in rapid execution of work.
Their construction can be well supervised and any defect detected can be rectified before use.
the reinforcements remain in their proper position and do not get displaced.
Precast piles can be driven in underwater.
The driving of adjacent pile does not produce adverse effect upon the already driven pile.
They can be loaded soon after they have been driven to the desired depth.
For the construction of under-reamed piles, a borehole is formed into the ground and then concreting it either with the help of a casing tube or without a casing tube. Their construction technique is different than cast-in-situ piles. These are suitable where: Vibration and noise caused by drivingRead more

Vibration and noise caused by driving piles are to be avoided.
Hard strata is deep such that it cannot be reached by driven piles.
