House Bolting

House bolting or earthquake retrofitting is a process that ties the home components together.
It increases the resistance to earthquake damage and decreases the risk of injury. In short, it significantly strengthens your home.

Weinstein Retrofitting Systems is the oldest and largest earthquake retrofitting company of Los Angeles, Orange County, and surrounding Southern California for residential and commercial buildings.

Since the Northridge earthquake of ’94 we have successfully retrofitted over 7000 homes in accordance with LA Department of Building & Safety, as well as FEMA’s guidelines.

A safe home is one that is built on a firm foundation and can withstand the push and pull forces of any major earthquake. By securely fastening the house to the foundation and securely connecting the house components together, the chances of withstanding the next earthquake are greatly improved.

What Really Bolts Your Home To The Foundation?

House MovementsMost residential homes are either built on slab or raised foundations. The home’s weight is the primary reason that keeps the house from moving or sliding off its foundation.

Bolting is the process of fastening the house to the foundation perimeter. Bolting your house is the best measure you can take to prevent damage inflicted by:

1. Earthquakes

2. Natural house settling

3. Water damage

Sliding failure occurs when a house is not securely bolted to the foundation. The sideways movement of an earthquake can cause the entire building to literally slide off its foundation (while remaining intact). Sliding failures are prevented by installing foundation bolts and framing anchors that tie the house to the foundation.

If the mudsill (the lowest timber supporting a building, located at or below ground level of your home) is not bolted, the lateral loads (back and forth motions) of an earthquake can shake the house off its foundation and cause it to collapse.

A common problem that occurs in areas with high moisture involves rusting of the bolts, regardless of which type is used.

If the bolt and the nut are corroded and stuck together, then the bolt should be replaced. Furthermore, in the process of removing the bolt and replacing the washers, many rusted bolts will snap off. Even though the bolts look sound, they can be rusted away where the bolt and the concrete meet – thus, where no one can see them.

Weinstein Retrofitting Systems will assess the foundation of your home and offer you the best earthquake retrofitting plan and products. By contacting us today, you are taking the best step possible in protecting you, your family, and your home.
