About Temporary Works 

Sheet Piles can be driven, extracted and reused many time.

Given the re-usability of sheet piles, there are several options available to optimize the cost of a project:

  • sheet piles can be rented,
  • purchased for re-sale ÔÇ£buy-backÔÇØ at the end a project,
  • or kept for future works.

Steel sheet piles can be utilized for temporary soil and water retention applications.

This category of applications is usually one of a temporary nature.

However, more and more the temporary applications are transformed to a permanent solution enabling a double function in the design.

If the total costs are considered using these products permanently, instead of removing and replacing them with a new building material, could provide a cost effective solution.

Some of these applications are:

  • Cofferdams
  • Trenches
  • Building Pits

Cofferdams are temporary enclosure structures built within, or across, a body of water and soil.

By pumping the water out the enclosed area a dry working space is created so that the actual building activities can proceed.

Enclosed coffers are commonly used for construction and repair of bridge piers; pump stations and other structures built within or over water.

These cofferdams are usually built with components consisting of sheet piles, walings, and cross braces. ÔÇ£strutsÔÇØ


In the civil engineering field of construction or maintenance, trenches are created to install or search for underground infrastructure or utilities (such as gas and water pipe lines or telephone lines, etc).

The construction of a trench is usually done in an environment with limited space Sheet piles therefore provide a dry construction space.

  1. light and heavy sheet piles (interlocking) which are driven and extracted by a suitable pile driving equipment.
  2. The bracing system which includes one or more layers of horizontally placed H-beams (waler beams), cross bracings (mostly trench struts or beams with spindle heads) and safety chains tosecure the H-beams in horizontal position.
  3. The equipment to drive and extract the trench sheet or sheet piles which can be
    a.) Hydraulic add-on vibrators which are mounted to an excavator boom
    b.) Telescopic piling rigs.
    c.) Hydraulic vibrators with power pack suspended from a crawler crane.

All parts of the sheet pile shoring system have to be designed according to actual site conditions (i.e. Pic of trenching / shoring pipe length and diameter, excavation depth, soil and groundwater condition, additional side loads, etc)

Working procedure:

  1. Make sure that the trench line is carefully and professionally protected on both sides to avoid any accidents.
  2. Check the trench line for existing underground utilities (cables and cable ducts, water and gas pipes, sewerage pipes, etc) and remove them before commencing any other work.
  3. Remove any pavement (concrete or asphalt) and any other obstacles.
  4. Provide sheet piles of sufficient length, section modulus and quantity along the trench and drive them into the ground.
  5. Start excavation with a suitable hydraulic excavator of sufficient operating weight and boom length.
  6. Lift the waler beams of designed section modulus and length into the trench at both sides and fix each beam to the top of the sheet piles to the correct position and the designed trench depth.
  7. Lift the trench struts or other bracings of designed buckling strength into the trench and fix them carefully between the beams.
  8. Continue to excavate the trench to the final depth and repeat steps 5, 6 and 7 in case that more than one layer of waler beams and bracings are required according to the approved shoring design.
  9. After laying the pipe or culvert the trench has to be filled-back and compacted in layers according to project specifications whereby also the bracing system (waler beams, trench struts and safety chains) will be removed in steps.
  10. After reaching the top backfill level extract the trench sheets or sheet piles by a suitable hydraulic vibrator.
  11. Clean the locks of interlocking sheet piles and return them.
Building Pits

Building pits are temporary waterproof constructions in which an excavation is executed for the realization of an underground building structure.

When enough space is available a pit can be dug under natural slope.However, usually this extra space is not available as roads, railways, or other buildings will be situated along the edges of the excavation.

The selection of the proper retaining system depends on a wide range of factors such as: Economical, soil conditions, protection of adjacent structures, ease of construction, environmental issues and more.
