On another side, There is certainly only a few good reasons that you may not choose to utilize the exam piles in the foundation.
Due to the extended attain from the crane used to setup the drilled micro piles ADF does not have to be able to have access for the pile rig at pile destinations. Micropile drilling can be achieved by reaching right into a cofferdam, around pipelines, structures or obstructions or perhaps in a river or lake without dewatering if vital.
The preferred engineering solution is to avoid the problem if possible. This is generally not a practical Answer and the most typical solutions contain the use of concrete piles or including protecting coatings.
