Is Concrete Pin Piles Reliable?
Pin Piles are also known as minipiles or micropiles. The small diameter grouted piles are high capacity drilled and are perfect for building foundations on sites where the ground conditions are poor, and the surroundings are sensitive. Pin Piles are well suited for raising the capacity of existing foundations, arresting ground move and foundation underpinning. Major structures need support on suitable underlying soils with the help of deep foundation systems such as drilled piles.
Concrete Reliability
Concrete Pin Piles are found in square, octagonal, cylinder and sheet pile. The long and slender column offers support and resist forces. One can inspect the size and shape prior to installation and how they will be impacted because of hammering and vibrating. The design and quality assurance of pin piles are a complete engineering solution and are known to be a cost effective product that is reliable and works under a broad range of subsurface conditions. These piles do not bulge in soft soil conditions and are able to maintain their shape during installation. They often gain capacity after installation and the shaft strength increases with time and thus adds to the load capacity, in the long run, they provide substantial cost savings and save time, labor and materials for the owner.

The major aspects when selecting Pin Piles are the design fundamentals align with drilling and grouting. These have proven to be a dependable geotechnical construction method for renewal of support under existing structures. After all, catastrophic events can result in ground losses that can compromise the support any structure. The drilled in elements range from 5 to 12 inches in diameter. Typically, they are made of steel pipe, cement grout, and a steel reinforcement. They execute very well under compression and tension conditions. They are usually installed in a broad range of access and ground condition, especially under difficult geological conditions.
Pin Piles are the right choice under underpinning situations to offer extra foundation capacity to the footings with little bearing capacity. They are ideal for supporting foundations and to allow an excavation adjacent to it. They offer lateral earth retention and vertical underpinning as well as provide support for distressed or undermined structures that have become weak due to burst pipes, erosion, landslides, mine subsidence, etc. If you need information about concrete pile cost, you can read it here.
Sometimes, an existing foundation system needs to accommodate a seismic retrofit and Pin Piles can add to the load capacity. These piles can be driven through the soft upper layers of the soil regardless of the groundwater conditions. As they carry superior structural strength, these piles will never fail structurally during static loading and static testing. They can be driven at various angles to raise the support for lateral loads.
Pin Piles are powerful equipment that is very economical to use. Moreover, as there is no loss of ground around the installation of each pile, the drilling is quiet and vibration free. Larger casing pipes can be used in the upper parts of the piles to create significant lateral load resistance. When configured properly, one can get high capacity is in both compression and tension. In tension, the capacity of Pin Piles is the same geotechnically. Advances in materials and methods improve the efficiency of driven piles.
