Beefing up existing concrete footing
Beefing up existing concrete footing
(OP)
Hello,
I have a single story block house I am considering adding a second story to. The house is located in Jacksonville FL on very sandy soil. The existing footing seems to be <= 16" wide and possibly less (sloppily poured so it's hard to tell). The existing block wall rises approx 10.5 feet above the foundation. Prior to talking with a PE I would like to become more conversant about the following: What are the methods for beefing up an existing footing so it can support a second story? Piles and pile caps? Shoring up the foundation similar to this link? http://www.preservation.org/foundation/
What are the relative costs, especially if I want to perform it myself under permit? Any suggestions appreciated.
Thanks
Paul

RE: Beefing up existing concrete footing
I would suggest that you speak to the PE since this is a case where the loads and existing size of footing and characteristics of foundation soils interact. You may even find that the existing footing is adequate, but may not be the case as you seem to say it is sloppy.
You may need a couple of drill holes to detemine nature of foundation soils etc. Your PE if he is geotechnical with foundation design experience may be able to do entire asessment. In other cases you will have to seek structural help as well.
The methods for beefing up whether piles etc are chosen after this type of evaluation and aassessment are undertaken
Costs are then determined for the possible options.
Generalay, retrofitting is more difficult than starting from scratch and one needs to be careful.
Good Luck
