Pile driving in New Orleans can be a tricky business. Piles are formed by the sitting of sedimentary layers under the surface of the earth. The process is named pile because of the way the piles are pushed through the soil to be replaced with solid rock, sand, or clay and the erosion and replacement are completed simultaneously.
Piles, being an engineering process, can present problems in terms of load handling, packing, and placement. It can also be tricky when it comes to vertical deflection due to changes in elevation or slope. As you have probably experienced, mud and water are difficult to remove from the ground and no easy to move past.
There are different locations that require different sets of pile operations. Geotechnical work involves “shooting” the foundation. The aim of the shot is to spread a thin layer of cement or epoxy across the base of the foundation. It is easier said than done as the mixture has to be managed in different areas of the foundation.
Foundation repair and development are other means of loading up your pile under New Orleans. The first method is loading the pile up using the excavator. The excavator will place the pile upon the earth, then do a slight refitting to avoid a deep wound and remove the loose soil from beneath the pile.
The second method is called foundation repair. The repair has a few points that must be taken into consideration. The biggest change is the addition of concrete reinforced with rebar. This has to be applied to the base of the pile using a lifting tool to make sure that the rebar sits properly in the soil and at the proper level for the pile to be lifted.
There are two systems that are used: the dry or “instantaneous” system. In this method, the load is put on the pile head and the existing piles are removed. The head has a simple edge, which can be set with tools that are provided.
This system is easy to use and allows for faster loading of the foundation repair. The disadvantage of this method is that the pile may not have the support it needs to complete the job. It is best to allow some time between each load and allow the pile to become accustomed to the change. This will allow it to load quickly, and the damage should be minimal and quicker than the dry pile.
