Foundation Repair is a term used by most contractors when they are repairing a foundation that has suffered some type of damage. If the damage is extensive enough, it may require structural changes to the foundation. For example, extensive water damage will have to be addressed with basement walls or another framing. This article discusses some of the different methods of foundation repair and how they compare to one another.
Foundation Repair Methods #1: In-ground Foundation Repair. Most homeowners do not realize that there is a better way to address house foundation repair than to dig holes and pour in the concrete. Foundation cracking is another method that is commonly used to repair house foundations. Slab jacking is a technique used to lift uneven or sinking concrete. This method is also called mud jacking, slab leveling, or concrete lifting.
Foundation Repair Methods #2: Drilling and Bleaching. Drilling is done by a professional contractor by slowly sinking a metal auger into the problem area to remove the damaged portion of the foundation wall. The area that is drilled is called a beam sleeve and the repaired area is called a beam pocket.
Foundation Repair Methods #3: Vertical Movement of a Basement Wall Due to Bank Pressure. There are several reasons why an interior wall of a building might settle to the bottom: it could be because of soil pressure, ground vibration, or vertical movement of a floor. If soil pressure is the reason for the foundation settlement, excavating a basement floor and finding no solid footing could indicate a slight bank. If soil vibration or vertical movement of a floor causes the interior wall to settle to the bottom, foundation repair should be sought.
There are several reasons for basement foundation problems. One may be related to the size and/or shape of a room. A room with irregular dimensions will settle more than a room with standard measurements. Other factors involved in foundation repair include grade defects (whether the ground has been installed properly), weather conditions, age of walls and insulation, and soil quality. Foundation Problems is most often found after tests and inspections by professionals.
There are many different types of foundation repair techniques. Most of these methods are effective but some can actually worsen a foundation problem. For example, using an ice pick to open a window can crack a windowpane. This will result in water penetrating the window and creating condensation inside of the room.
When faced with foundation repair and foundation issues, homeowners should seek the advice of a licensed foundation repair contractor. A licensed contractor will know which techniques are more effective than others and will use the most appropriate techniques based on the circumstances. Some of the techniques used by professionals include concrete pumping, polyurethane crack sealers, pressure pumping, drainage materials, site stabilization, grading, encapsulation, site improvement, piers, foundation leveling, exterior repair, slope control, prefabrication, site engineering, liquefaction, and more. It is important that you hire a professional to properly assess your foundation repair needs and to provide recommendations for the best course of action.
Many in the industry believe that concrete piers are the most effective at repairing foundation problems. Two of the most popular piers that have been recommended for basement repair and foundation repair are helical piers and concrete piers. Helical piers are installed by placing the bottom edge of the pier on a concrete slab. The helical piers are designed to rest on the floor above the foundation. These piers are then covered with a crack sealant or other liquid solution to prevent water from penetrating and to prevent settling.
