Quay Wall

QuaysÔÇ»commonly consist of a fixed platform, either closed off by quay wall or as open deck on piles. The typical objective of a quay is to unload and reload vessels as quickly as possible. Quay walls are usually earthÔÇ»retaining structures at which ships can berth.

They can be located on the sea, a lake or a river, inside a harbour or a canal, and are equipped with the necessary superstructure to allow the common operations of transshipment of goods.

The H- Beam & Sheet Pile combi wall and tubular combined wall systems offer hundreds of combinations in a wide variety of steel grades for the designer to choose from. The entire quay structure must be able to satisfy numerous requirements imposed by:

  • location
  • soil conditions,
  • sea water (high tide, low tide, etc) & groundwater levels,
  • wave conditions,seismic conditions.
  • service conditions, service life (durability),
  • size of ships that will berth (draught),

Combined wall solutions

Conventional steel sheet piles walls were replaced with combined walls which consist of two complementary elements: a primary stiff element (king pile, H-beam or Tubalar pile and a secondary flexible element (intermediary sheet pile, predominantly ZZ sections).

The result is an overall safe and cost-effective high capacity retaining structure, with a high stiffness and high bending moment capacity.


AÔÇ»jettyÔÇ»is a structure that projects from the land out into water. Often, “jetty” refers to a walkway accessing the centre of an enclosed waterbody.

For regulating rivers:
Another form of jetties,ÔÇ»wing damsÔÇ»are extended out, opposite one another,ÔÇ»from each bank of a river, at intervals, to contract a wideÔÇ»channel, and by concentration of the current to produce a deepening.

For berthing at docks:

WhereÔÇ»docksÔÇ»are given sloping sides,ÔÇ»openworkÔÇ»timber jetties are generally carried across the slope, at the ends of which vessels can lie in deep water or more solid structures are erected over the slope for supporting coal-tips. Pile work jetties are also constructed in the water outside the entrances to docks on each side, so as to form an enlarging trumpet-shaped channel between the entrance,ÔÇ»lockÔÇ»or tidal basin and the approach channel, in order to guide vessels in entering or leaving the docks.

Jetties are usually built as a deck on piles structure, founded on individual vertical or battered steel piles driven into the soil, and topped by a deck built with steel or reinforced concrete. Steel HP piles and spirally welded tubular piles are ideal for this application. Alternatively, jetties can be executed as a double sheet pile wall, with one or more anchor levels.
