Drainage and Seismic Retrofit

Water is one of the top reasons for foundation failure, structural subsidence and structural sliding. Seismic retrofit helps secure your foundation against the inevitable earthquakes we feel here in California.


Water is one of the top reasons for foundation failure, structural subsidence and structural sliding. You know that crooked doorway at your parent’s house, it is most likely not the fault of the people who built the house. The probable cause is the house sinking or sliding from too much water content in the soil around and under the home. Excessive water destabilizes the soil the house is built on making it unstable to carry the load.

Over the years, people have come up with many different ways to deal with this problem, such as high p.s.i. ratio concrete and waterproof membranes under slab, but there is only one failsafe process and that is to collect the water at a central point and eject it away from the structure. This process can be straightforward or complicated, but it is never impossible to do.

Here are signs and things to review for these types of services:

  • White salty deposits on foundation
  • Damp crawl space
  • Cracks in foundation
  • Uneven floors
  • Standing water around house

Seismic Retrofit

Seismic retrofit is much less involved than foundation work but just as important and necessary. A new foundation will not keep your house from "jumping" off it's foundation and it's load in an earthquake, instead retrofit and shearwalls will help do that. Shearwall retrofit is the best line of defense against the earthquakes because it physically attaches the first floor to the foundation. The foundation provides a solid stable condition for the house and it's load. The shearwall holds the house to it.
