Default How to set pilings?

I am going to extend my dock into my back yard a shot way (30 feet ish). My question is how to properly set pilings on land

A) auger holes and drop them the n?
B) auger holes and make a concrete pier and mount them on the pier?
C) Jet them in?

does ot differ based on how close to the water table?

I jetted a BUNCH of pilings in Gulf Breeze, FL when I built a house there. I owned what is called a "trash pump". You can rent them at a lot of Home Depot's though. I jetted pilings about 4'-6' deep for the retaining wall in the back yard. The dock and boat lift I jetted deeper. The water table was about 3' to 5' down in the back yard. If you have a lot of roots in the ground, a powerful (not handheld) auger may be the way to go.

I would imagine you could get away with auguring the poles roughly 6-7' in the ground. I doubt you would need to pour any concrete, depending on how good your seawall is. I've augured poles in the backyard of my house when I built my tiki hut/deck and haven't had an issue.

I used a pressure cleaner to augur in a dozen 4 x 4's for a dock when I lived on a lake years ago. It extended about 8 feet out into the water. Sandy bottom and they went in easy. The dock has survived about 30 years.

Make sure you get permission from the EPA first.

there is no reason you canít do that other than roots or other obstructions. However itís going to make a mess and the holes probably wonít fill back in nicely for a long time.

If you have any concerns about flooding from storms, then cement is a good idea. Otherwise not needed

Jet them in I just built a dock on my place and a couple barges to do it with . If you can get them upright and straight and not in rock then jetting is easy. This was my first time doing it and when I was at the end I was setting 35 footers by myself . Trick is getting the hole straight down and the pole straight from the very start.

tbouknight- Nicely done !! Did you have much trouble getting permitted ( local/state/ US Army COE?) to build the PT dock in that area? That would be a looong process here with no guarantee at all of eventual success.

Permit was not a problem. All land in Beaufort sc is applicable as long as the dock is no longer than 1000ft and creek must be wide enough that the dock doesn't enter the travel path of the creek. They are done bu DHEC and a permit can take 6 months to a year to get. Just enough time to build a couple barges and order materials.

Up on the hard I would dig them out with an auger or even a regular post hole digger if your "dirt" is sand like it is here. Dig a couple inches deeper than your final post height would dictate, Pour gravel in the hole and tamp it in with the post to get the post height right. Sometimes it is easiest to lag bolt a short 2x3 or something on the post to use as handles when you are tamping it in and jogging it around. Tamp the back fill dirt in on short lifts until it is full. (something like 5-6" of dirt and tamp it in well) It will feel like concrete when you are done.

What am I missing here???? Dry ground? right? 32 inches with a post hole digger, set them in dirt, tamped in, and done.....they will never move unless flooded and something slams into them....
if it makes you feel better drop half a bag of Sacrete in bottom of whole, still in the bag, no need to add water.

At 32Ē in sandy soil you donít think they will settle over time?

I just knew that was Beaufort County from pics. Any chance that is Hilton Head Island? Lived there on Calibogue Cay 80's and 90's.
