King Piles


The HZ®-M walls are combined systems incorporating: 

  • HZ®-M king piles as structural supports,
  • AZ® sheet piles as intermediate infill elements.

Systemwise  assembly of these basic elements yelds a multitude of possible combinations.
All combinations are based on the same principle: structural supports comprising one or more HZ®-M king pile sections alternating with intermediate double AZ® sheet pile sections.


Structurally, the HZ®-M king piles fulfil 2 different functions:

  • as retaining members, they resist horizontal loads resulting from earth and hydrostatic pressures,
  • as bearing piles, they resist vertical superimposed loads.

The intermediate sheet piles have only an earth-retaining and load transfer function and they may be shorter than the king piles.
