Curved Wall and Gate Piers in Surrey: Screw Piles for a Prestige New Build
| Application | Curved wall ring beam + automatic gate piers |
| Location | Surrey, United Kingdom |
| Piles | Helical, Ø76.1 mm (triple helix) |
| Pile count | 8 |
| Pile length | 4 m |
At a prestige new build in Surrey, UKHelix installed Finnish-made helical piles to carry two things at the front of the plot: the ring beam under a curved boundary wall, and the piers for the automatic entrance gates. Eight piles carried the lot.
The piles were Ø76.1 mm with a triple helix, wound down to 4 metres and set out to follow the sweep of the wall. Their heads carry a ring beam that runs the length of the curve, and the wall sits on the beam. A curved run like this suits screw pile foundations well, because each pile goes in exactly on its mark rather than being cast in place.
The plot had one way in, and it had to stay open while the work went on, so the job was split in two. UKHelix piled one side of the entrance first, waited for the site access to be swapped across to the finished side, then came back and piled the other. The swap cost a little patience, but once the access moved the crew pushed on and still had all eight piles in within the day.
Gates that open and close on their own leave no room for a pier that sits proud or out of line, so the crew checked levels as each pile went down and kept the heads true for the wall and gate steel to follow. Eight piles, one curved wall and a set of gates, set out and wound in over a single day once the access allowed it.
