How the Right Foundation Repair Method Can Help Save Your House from Sinking
Los Angeles lies a few miles from the San Andreas fault, which makes it highly susceptible to earthquakes. Because of this, most cities in the area have implemented ordinances that require the inspection and retrofitting of buildings, or foundation repair for those that need it. Non-compliance with the city ordinances can result in fines, or, in the worst violations, the closure of businesses and revocation of business licenses.
Many contractors that perform foundation repair in Los Angeles, however, use methods that do not fully protect against the effects of earthquakes.
For example, standard methods involve the total replacement of damaged foundations with new ones. While a new foundation is meant to be a protective measure against sinking, it does not address groundwater saturation, which occurs after a period of heavy rain. It also does not protect it against the effects of soil liquefaction, which happens when saturated soil is shaken strongly, as in an earthquake. In areas where silt has been deposited, such as the alluvial floodplains formed by the old Los Angeles River, the ground could be unstable and can easily be liquefied if an earthquake is strong enough.
The only sure way to secure your house’s foundation is to connect it directly to the bedrock below it. To do this, helical piers and anchors are screwed in mechanically, up to a certain depth where bedrock can be found. Once the piers have reached the bedrock, steel brackets are mounted to support the foundation, giving it near-permanent stability that bypasses the effects of soft soil.
This method is ideal for soils such as sand, silt, and clay. It is also recommended for housing developments where the ground is usually compacted fill soil from nearby hilltops. The presence of vegetation, particularly larger trees, is also indicative of a prime candidate for this method, as trees put down roots that pull up water from the soil, making it dry out and shrink gradually.
The key to a stable house is a secure foundation. Protecting your foundation by applying the correct method will let you sleep better at night, knowing that you will not see cracks or sinking when you wake up.
