Foundation Piling repair, sleeve with concrete

Nice. St George is very nice indeed. Paddy's Raw bar is always a treat down there.

 

I strongly recommend using a professional design, particularly if the piles are driven, not simply placed in a drilled hole. In most of FL, the piles rely on the friction of the soil on the pile rather than any semblance of rock below grade...there isn't much. When the sandy soil gets saturated, your bearing capacity goes to shit.

 

Curious, what type of footers are used more down there, the helical screw type or concrete footers? The concrete would just be based on weight, helical on friction.

 

There is a lot of guessing going on

For sure a very creative PE should be used.

Maybe a simple grade beam will suffice and eliminate the need to cut through your slab too much.
Lots of guessing without pics. I have seen creative ways just depends on the field conditions.

You only need to be 12” below grade for the footing. slab construction is predominantly used. Maybe you can eliminate these spot posts somehow with a grade beam.

 

Now that is a very interesting idea.

 

Spread footings are common away from the water. Tidal action brings with it more challenges than simply resisting the forces of gravity.

 

Went there 2 weeks ago. The oysters were yummy.
