A pile splice joins two segments of a driven pile, using either a weld (typical for H beams), grout or mechanical means (typical for precast concrete piles). Pile splices enable the use of shorter segments, which allows for driving piles in low-headroom situations such as under bridges or inside buildings. [ 1 ]
Splicing timber piles is still quite common and is the easiest of all the piling materials to splice. The normal method for splicing is by driving the leader pile first, driving a steel tube (normally 60–100 cm long, with an internal diameter no smaller than the minimum toe diameter) half its length onto the end of the leader pile.
Screw piles are typically manufactured from high-strength steel [1] using varying sizes of tubular hollow sections with helical flights. The pile shaft transfers a structure's load into the pile. Helical steel plates are welded to the pile shaft to suit the site specific ground conditions. Helices can be press-formed to a specified pitch or ...
Franki piles can be used as high-capacity deep foundation elements without the necessity of excavation or dewatering. [4] They are useful in conditions where a sufficient bearing soil can only be reached deeper in the ground, [5] [6] and are best suited to granular soil where bearing is primarily achieved from the densification of the soil around the base.

Larssen sheet piling is a kind of sheet piling retaining wall.Segments with indented profiles (troughs) interlock to form a wall with alternating indents and outdents. The troughs increase resistance to bending.
Once initial piles are set with concrete, other shafts are augured between them, slicing into the original piles, with the new ones receiving rebar. The finished result is a continuous wall of reinforced concrete that aids and protects workers during excavation. [citation needed]
Chain splice – Attached the working end of a rope to a chain. [7] Figure-eight "splice" knot – A splice-like bend knot used for joining two ropes. Horseshoe splice – A cut splice where the two sides of the loop are of unequal length. Long splice – A splice used to join two rope ends forming one rope the length of the total of the two ropes.
