What are the advantages and disadvantages of timber piles?

Timber piles have small bearing capacity. Untreated timber piles above groundwater may last more than 25 years but are not permanent. Timber piles are prone to damage by hard driving. Timber piles cannot be driven through hard stratum or boulders.

What are the disadvantages of pile foundation?

Disadvantages of Pile Foundation

• A pile can be damaged quickly by driving through stones and boulders.

What are three causes of failure of piles?

The failure of the pile foundation may result from any of the following causes:

• Lack of adequate boring.
• Inaccurate soil classification.
• Soft strata under tip of pile.
• Inadequate driving formula (wrong data)
• Improper size of hammer cause insufficient penetration, too light or damaged if too heavy.
• Misinterpretation of load.

What are the advantages of piles?

Advantages of Pile Foundation: The piles can be pre-prepared according to its length. The precast process reduces completion time. It can be installed over a very large area & very long lengths. We can use piles in a place where drilling is not required.

• As the building is made of discrete components, the joints between adjacent members have to be sealed with special sealants to make them waterproof.

What are the disadvantages of steel piles?

Disadvantages of Steel Piles:

• Steel piles have a high possibility of damage from corrosion and electrolysis.
• Steel piles are relatively expensive unless the bearing stratum can develop large pile capacity.
• Steel piles are less effective than friction piles.
