What is Foundation Retrofitting?

Foundation retrofit, also known as earthquake retrofit or brace+bolt retrofit, refers to the process of securing and improving the connection between the wooden frame and the concrete foundation of a building.

Buildings constructed before the 1960s were merely nailed down to the foundation. However, new seismic codes came into effect in the 1960s making it mandatory for structures to have a better foundation for wooden frame connection. Newer structures, thus, are not simply nailed down but also incorporate large bolts, known as anchor bolts, throughout the foundation that firmly secures them in place. Foundation retrofitting, in this manner, prevents the structure from sliding off or shifting away from the foundation during seismic activity, making it more resilient to ground motion or soil failure. Southern California is one of the most seismically active regions in the world, experiencing frequent tremors as well as high magnitude earthquakes more frequently than other places. As a result, Los Angeles homeowners must pay special attention to include a foundation retrofit in their property planning.

Method of Foundation Retrofitting

The method employed to retrofit a foundation depends on several factors such as when the house was built, where it is situated, how well the foundation is performing, and whether or not it has previously been damaged by seismic activity. Retrofitting should ideally be done on a stable foundation.

If the foundation is poorly constructed or was subject to prior ground-shifting events or bad retrofitting jobs, making the necessary repairs is vital before starting the retrofitting process. Once the repairs are made and the best procedure for the foundation in question has been ascertained, the actual process of retrofitting begins. Common techniques include the addition of new reinforced concrete shear walls and installing steel braces. Jacketing is another popular technique that increases the lateral load capacity of the structure in a uniformly distributed way. Choosing the right method is crucial to successful seismic retrofitting. To this end, it is important to ensure that your property is in the right hands. At Alpha Structural, we make sure that the property is evaluated accurately to ascertain which technique would give the optimum solution. Our expert team values the needs of your property over everything else and has years of experience in foundation retrofitting.

Benefits of Foundation Retrofitting

When an earthquake is in action, the ground shifts from beneath the house while the structure itself is held in place by gravity and inertia. These contradictory motions cause large-scale damages to the property when the foundation-to-frame connection is not sturdy enough. This is where foundation retrofitting can come to the rescue.

A foundation retrofit drastically improves the strength of the foundation-to-frame connection, ensuring that the building’s wall and floor frames remain attached to the foundation in the event of an earthquake. This goes a long way in preventing extensive damage to the building. Alpha Structural specializes in home earthquake retrofitting, house bolting, foundation bolting, and residential seismic retrofit, all of which can prepare your home to better deal with earthquakes.
