Being assured that your home can withstand even the strongest known earthquake is a comforting thought. However, a foundation that is as strong as that needs to be maintained regularly. Needless to say, a home with a foundation built twenty years ago is not as stable as it had once been. Even so, all you really need is maintenance and upgrades. A good foundation will make your home earthquake-proof.
If you want to know if your home is strong enough to withstand a strong earthquake, you better have your foundation checked. Consult with a Plano foundation repair expert to know what to do in case your foundation is not as stable as you want it to be. Here are some of the things that they would do.
- Identify weak points
When it comes to earthquakes, it is the foundation of your home that would sustain most of the stress. While the damage may not be seen from the above, you never know what damage happens underneath. Older homes aren’t built to sustain earthquakes and that’s a fact. If your home if built a long time ago, then you have to hire a structural engineer to identify its weak points.
- Have the foundation inspected
Foundations should be secured into the sill plate underneath your home. Foundation repair experts can inspect this by going down the basement or crawlspace to check whether the steel anchors are attached to the wall. Without anchor plates, your house is at the risk of crumbling when a strong earthquake hit. With the help of experts, it should be fast and easy to install anchor plates to your home’s foundation.
- Anchoring the foundation
The anchor plates are connected to your home’s foundation through nuts, bolts, and epoxy. Foundation repair experts use electric drills to anchor the plates fast and easy. The use of round washers is discouraged. You want stronger and tougher ones for your home’s foundation. It should also be spaced six feet apart or closer, depending on what’s the local building code mandates.
- Brace cripple walls
Cripple walls are special house features that carry the weight of the structure over the foundation. These walls have to be braced well to withstand the earthquake. Otherwise, the house will sway during an earthquake, with the possibility of collapsing.
- Tying the slab foundations
If your home is built on top of concrete slabs, then you have to tie the sill plate to it via the metal straps or volts. Sometimes, it is necessary to remove a part of the drywall to check if the slab is correctly attached to the plates.
- Installing post and pier foundations
Post and pier foundations are held by wood posts or concrete blocks. If your home is not duly supported, then you have to brace it with the use of post and pier foundations. This process may require pouring concrete, which is why it’s one of the most expensive ways to reinforce your home. Even so, it’s one of the best ways to repair home foundations.
