Foundation Repair Methods: Seismic Retrofitting

A Look at Common Foundation Repair Methods: Seismic Retrofitting

Seismic retrofitting is a foundation repair method that involves the modification of existing structures to make them more resistant to the effects of seismic activity, ground motion, or soil failure caused by earthquakes. In Los Angeles, a city that’s prone to higher occurrences of seismic activity, there is a city ordinance that mandates property owners to retrofit their homes, regardless of how old or newly-built these are. If they fail to comply, they can be fined stiff penalties while commercial property owners risk being shut down as well.

Some common seismic retrofitting techniques:

Foundation Bolting – This technique aims to strengthen the connection between a structural wood frame and a foundation made of concrete by bolting wood beams from the former into the latter. Doing so can decrease the risk of your home sliding off its foundation during an earthquake.

Helical and Push Piers – Strong steel piers are screwed or driven deep into the ground and then attached to the foundation. Ground movements can weaken or damage foundations, but with helical and push piers to provide additional structural support, your home or building will be stable enough to withstand the effects of the movement.

Cripple Wall Bracing – As the name suggests, this technique braces the cripple wall or short wall typically made of wood that extends from the foundation to the first floor. While the cripple wall provides support to the entire weight of the structure, it is also known to be the weakest and most vulnerable to earthquakes. Generally, the cripple wall is braced with metal to strengthen its connection to the foundation.
