Screw piles
Down to the bearing layer, with extensions if needed.
Jetties and marinas
Jetties, pontoons and marinas on screw piles
A jetty or boathouse stands in a soft bed and has to stay straight for years. We screw piles through the water down to firm ground: no dewatering, no concrete curing in the water, and the bank stays untouched.
Why no concrete?
- No dewatering and no concrete in the water
- Through silt and soft ground down to firm ground
- From the bank, by hand or from a pontoon
- Ready to load at once
- Removable if the jetty is ever moved
Which foundation?
By hand
In a marina we also install smaller piles by hand, without a heavy machine.
Protection
In the zone where the water rises and falls we choose a thicker wall or coated piles.

Frequently asked questions
Is a permit needed?
Work at or in a watercourse often needs permission from the water authority. Check beforehand.
Do piles rust in the water?
In the splash zone we choose a thicker wall or coated piles.
Can it be done from the bank?
Often yes. Otherwise from a pontoon, as for the boathouse in Lier.
