text: Foundation Underpinning Options and What to Know
  If you are facing a foundation underpinning for your home, then you may not be aware of what underpinning actually means. There are three main styles of underpinning that may be used. As the homeowner, you need to understand these three options and what each one means. Though you may not have a choice in some cases, depending on your location, you still need to be aware of what will be happening during the underpinning process.
  Piled Raft Underpinning
  Piled raft underpinning is a method that contractors will use if the entire foundation needs to be repaired. This generally happens when there has been massive storm damaged causing the foundation to slip or shift. This shifting can cause cracks and damage within the foundation and throughout the entirety of the foundation. The piled raft underpinning allows the contractor to provide stabilization ties through the entire structure. The piled raft method also is ideal for foundations that are deeper than others where alternative underpinning methods can be used. This also reduces exterior access to the foundation and reduces damage to your drainage system.
  Screw Pile Underpinning
  Screw pile underpinning is usually what contractors choose when they have smaller crews and when traditional methods are not going to work. The benefits to this method allow two to three people to handle the underpinning. The screw pile and brackets also can be installed with smaller equipment. This is ideal if the construction crew is small and the equipment is limited. The screw pile and bracket method withstands heavy winds and rain as well. If the underpinning will take longer than normal, due to various reasons, then this method may be the ideal option for your foundation repair and for the safety of your current foundation.
  Pile and Beam Underpinning
  There are a few reasons your contractor may want to use pile and beam as the foundation underpinning method. One of the reasons may be due to the heavy load capacity of the foundation and building. Another reason pile and beam may be mentioned is because it is a faster underpinning method. If you have a limited access to your foundation, and if disruption to the soil may cause damage to homes that are nearby, pile and beam may also be the option contractors want to use.
  These are the three main options you may be facing for your foundation underpinning. If there are alternatives, a contractor, like those at Pro-Pin Professional Underpinning, will let you know. Make sure to ask the contractor what the other processes will cover and how you need to prepare for any other processes they mention. Also, make sure to ask any questions you have during the foundation consultation. This will help you prepare and make choices that work best for you and your home.
