Principle of pile foundations

A pile foundation is necessary when the loads of a building will be higher than the upper soil layer can take. Piles are installed primarily to avoid settlements which could result in big damages and dangerous situations. In a limited number of projects piles are installed as ‘tension’ piles these are installed to prevent the object from lifting out of the ground. A well-known example are piles installed under the high tension electricity piles. Due to high forces created by wind the piles need to be ’anchored’ in the ground.
