Micropile Processes July 16, 2010

Utilizing the micropile process in the formation of proper foundational support establishment in the field of commercial construction has become a dependable manner for construction firms to ensure consistent structural integrity.

Micropiles (often referred to as minipiles, root piles, pipe piles, and needle piles) have become a viable alternative when challenges arise on a jobsite that restrict the use of conventional pile driving techniques for traditional deep foundation system applications. Micropiles are drilled and grouted piles capable of handling weight loads up to 500 tons, depending upon the type of micropile utilized.

Often micropiles are the only alternative when physical limitations do not allow the use of massive pile driving rigs or vibratory driver/extractor systems. Examples of limitations include a job site being too close to an existing structure or an underground cavity; such as a river. Crews working in congested areas in metropolitan settings also present challenges that do not permit overhead clearance; which is necessary for standard piling driving techniques.

Typical minipiles are a combination of steel reinforcement and grout (a cement based product that cures to an extremely hard end state, allowing it to withstand pressure not allowable by typical concrete products). The relationship of the elements creates a structurally sound bond with amazing resilience
Micropiles have proven to be the application of choice when existing buildings need reinforcement. Micorpiles are used to replace deteriorating foundations, as well as to provide additional support during the renovation of existing structures; they are considered to be a welcomed method when compared to most traditional underpinning processes.
