HELIX piles
Small piles from 0.7 to 3.2 m with a helix: handy under terraces and decks, installed by hand.
Terrace and deck foundation
A terrace, deck or jetty without concrete
A timber terrace, deck or jetty stands on a grid of screw piles or ground screws. No concrete, no digging, even on a slope or by and in the water.
Why no concrete?
- No concrete and no digging
- Level, even on a slope
- By and in the water, without dewatering
- Bank and planting left untouched
- Ready at once for the bearers
Which foundation?
Ground screws
For a terrace at ground level, ground screws with a continuous thread are often enough.
Screw piles in the water
For jetties in a pond or on a river we screw the piles down to bearing ground, also from a pontoon.

Frequently asked questions
How many piles does a terrace need?
That depends on the size and the timber section of your bearers. The pile calculator gives you an indication and a plan in one minute.
Can a deck go into the water?
Yes. We screw the piles in at the edge and in the pond, without dewatering and with no concrete in the water.
Concrete or screw piles for a terrace?
For a timber terrace, screw piles or ground screws are almost always faster and cleaner: no digging, no curing and no waste.
