Ground screw, also known as helical piers, anchors, piles or screwpiles, are deep foundation solutions used to secure new or repair existing foundations. Due to their design and ease to install, they are most commonly used whenever soil conditions prevent standard foundation solutions. Instead of requiring large excavation work, they thread into the ground. This minimizes installation time, requires little soil disturbance, and most importantly transfers the weight of the structure to load bearing soil.

Benefits

  1. Q235 steel hot-dip galvanised at 80 µm average coating — the foundation matches the corrosion class of the structure above it.
  2. 0 excavation — threads into load-bearing soil with minimal disturbance and immediate load transfer.
  3. Sized by on-site pull-out tests where soil is soft or undocumented; 12-year warranty.

Frequently asked questions

What if the soil is soft or unknown?

On-site pull-out tests size the piles, so foundation rework never happens.

How does it handle corrosive environments?

The ISO 9223 class (C1-C5) picks the coating - HDG, ZAM or 6005-T5 aluminium - so rust never becomes a warranty fight.
