Bored piles, also known as replacement piles, are a commonly-used form of building foundation that provide support for structures, transferring their load to layers of soil or rock that have sufficient bearing capacity and suitable settlement characteristics.

    Why and When to Use Concrete Piles? FPrimeC

    Types of Concrete Piles. Concrete piles can be either pre-cast pile, or cast in-situ. Concrete piles are generally reinforced. Pre-cast Concrete Piles. For pre-case piles, the reinforcement brings extra strength to resist bending moment during pile pick up, transportation, vertical loads, and bending moment as a result of lateral loads.

    Common Pile Driving Problems and Solutions

    20-11-2019· Pile driving is often a cost-effective and time-efficient method of driving support posts (piles) into the earth. But because you're working with soil and other hidden features in the earth, there is an element of the unknown, and things don't always go as planned. Whether you are driving concrete, steel, or wood piles, any number of problems are common.

    PILE LOAD CAPACITY CALCULATION METHODS

    Concrete and steel piles are most common. Driven piles which tend to displace a large amount of soil due to the driving process are called full-displacement piles. Cast-in-place (or bored) piles do not cause any soil displacement, therefore, they are non-displace-ment piles. Piles
