Seismic Retrofitting A Crawlspace By Installing Support Posts In La Mesa, Ca
The before photo shows a post that is not properly supported. Seismic activity over a number of years will cause a post to shift like this, causing sagging floors, sticking doors and windows, and sometimes cracks through the walls. To correct this problem as shown in the after photo we installed 17 new posts with pads and caps like the one you see. Now the posts are correctly supported and more resistant to seismic activity.
