Hammer-in anchor

A hammer-in anchor provides definitive anchorage for moderately to heavily stony ground, or even for certain types of slaty soil.


  • Saves time during preparation and installation.

  • Easy and effective anchoring at a competitive price.
  • Model tested and adapted according to requirements determined by the customers.
  • Anchors respect the environment thanks to their minimum above and below ground encroachment.
  • The products are available from a large distribution network.
  • Anchor design is the fruit of research, testing, and validation by a control office.
  • Certified welds protect against corrosion.

Selection of rockers and cables

We offer four rocker models: No.1, No.2, No.3, and No.4.
The anchors' resistance when extracted depends on the type of soil, the rocker model, and the cable's own resistance. The ranges are displayed in the table below:
-The minimum value corresponds to an unstable soil type such as sand or loose gravel.
-The minimum value corresponds to highly stable soil type such as clay.
