Our Process
These homeowners await the arrival of a retrofitting crew in hopes of keeping their family safe during future earthquakes.
The truck arrives and the work crew has placed its sign in front of the home to announce this home owner’s prudence.
New trench excavated under front of the house to carry lateral loads that may be generated by future quakes.
New reinforcing steel is erected in the trenches making ready for concrete placement.
Pockets are created in the existing brick perimeter wall with new bolts at six foot centers to be incorporated in the new sister wall.
New bolts are also hung in each corner for the new concrete steel reinforced sister wall.
Forms are established under the front wall.
High density concrete is pumped into the trenches and forms through a pump hose.
Cripple walls are added to help transfer loads from the floor diaphragm.
The new cast in place anchor bolts are torque down with square plate washers included.
Plywood shear walls are installed to complete the load transfer from the floor diaphragm to the new reinforced foundation.
The structural grade plywood is nailed off per code with an air gun.
The project is complete, signed off by the City as the newly protected family pose with the project foreman.
