October 17, 20206 yr Hey guys, How much should I be looking to pay for approximately 30 linear meters of sheet piling on a supply and install hire basis. 15meters each side required on neighbour party walls We will then do a 3m dig, so I probably need 6m long sheets so we have a 50% sheet in the ground at least.
October 17, 20206 yr How do you plan to get them back out ..?? Surely you are better off putting them in and leaving them in - just get the tops cut off and cast a concrete footing on top and use it as the base of a wall. You could budget around the £200/sqm for sheet pile so you’re about the £10k mark for it installed depending on ground conditions.

There is an extractor that can be used to remove them. If they stay in, cost goes up as they are about 7k for 90x6m lengths

If you are having to put them on to build up to the edge of the plot then how will you get the machinery in to get them out ..?

We will have hollowcore concrete floors, but even so, might not take the weight of a 12 tonne machine. May need a large machine with good reach from the road.
October 17, 20206 yr You will need one heck of a machine to reach back 15m..!! I’d be looking at leaving them in or using them as part of the structure.
October 17, 20206 yr Am I just missing the obvious? Surely a days crane hire will have them out easy enough at far less cost than purchasing outright??

To do a contract lift you would need to know the load. How you would accurately calculate the loading of the ground “grip” plus the sheet and friction of the next pile would mean you would end up with a very big crane to ensure a safe lift. Temporary sheet piling is normally done for cofferdams and whilst retaining walls are built, and really where you have the access to drive and remove easily. TBH with this I would just drive lines of concrete piles and leave them in situ and then cast around them for the retaining basement walls.

I will admit my knowledge of basements is nil, I toyed with the idea, dismissed it so left it at that. It seems there are many ways to skin the cat and the only way to work out whats best is to work with an engineer and cost the options up so you can compare them against each other.
