Pins in the bottom of the tubular drilled in beyond the point where it can’t be driven any more and grouted into place, belts  and braces methodology probs included as part of design  as the ferries up here often give the pier a good wallop with the winds they operate in. Pics show the caisson pier extension unit in place and being floated in recently.

What, so you get some skinny little fella to drop down inside the tube, trusty makita in hand, pop through a couple of holes and hammer some roadpins through the sides?  You've got us interested in the mechanics here, of something we don't know about or understand.  We now need more details now You've set the ball rolling! 🤯

[Mr. Ed]

Agreed! We want more!!

The reality is it’s a fairy simple but heavy duty concept. The tubular pile once it’s reached resistance has a drilling rig set up over it and a hole drilled through a drill casing to take a large steel pin of a predetermined length, the pin and annulus of the tubular are then filled with grout. Don’t ask me how the engineers work out the drill depth,pin size or grout type 🙄, it’s normally a specialist contractor who will do such things. Loads of stuff online about it and the consequences of getting it wrong particularly in sheet pile walls.

Cool, thanks for giving an explanation, and improving my education. The things we learn on arbtalk.👍

Contact Mackleys near Brighton. They remove and install loads of it. Bring a large trailer and be amazed how little you have on it before your overweight.

Now your talking, some nice replacement timber on site at min. Between 300-360 square and up to 8-9m😍
