Earthquakes can either be low intensity earthquakes or high intensity earthquakes which might claim lives and cause damage to properties, hence the need to have your property retrofitted for earthquakes.
Having a seismic retrofit for your property will reinforce your property’s structure and make it less susceptible to earthquake damage. Unlike other types of retrofits, the cost of seismic retrofit is not standard because it’s dependent on a number of factors such as location of the property and age of the property which in turn determine what kind of methods will be used to strengthen the property. Some of these methods include :
Cripple Wall Bracing
A cripple wall is a wall that is less than a full story height and is usually placed between the first floor and the foundation because that is the weakest part of most old buildings. During an earthquake, the area between the foundation and the first floor is usually the first to collapse so by having a cripple wall in that area, you will drastically reduce the amount of damage done to a building during an earthquake.

Foundation bolting is yet another method in which you can retrofit your property against earthquake damage. Foundation bolting is the process which prevents the up and down movements of your property during an earthquake as it might displace an unbolted property off it’s foundation. To bolt a building to it’s foundation, either expansion anchor bolts or sill plates are used. Expansion anchor bolts are used to directly attach the building to the foundation while the sill plates are used to attach the foundation and building on the sides if the space doesn’t allow direct bolting.
Wood blocking is another way of strengthening your property against earthquakes without adding much to the cost of seismic retrofit. Wood blocking involves the addition of pieces of wood in between two studs in order to strengthen them. This is an easy method and yet it’s also very efficient in preventing the wooden studs from collapsing during an earthquake.
