Are sheet piles temporary?

Introduction. Sheet Piling is used to provide temporary and permanent walls in the construction industry. Sheet piling is used as excavation support and for soil retention. It creates a border which keeps the soil back, away from the structure.

Are sheet piles reusable?

Steel sheet piles can be used and reused several times for temporary applications, thus reducing the environmental impact each time the sheets are re-used. At the end of life, when they cannot be reused anymore, 100% of the steel can be recycled.

How does sheet piling work?

The concept of sheet piling is pretty straightforward. Wherever a wall or siding needs to be held back, steel sheets are wedged into the earth at predetermined intervals. The sheets are driven into the soil with vibratory or impact hammers. In some cases they may be installed with hydraulic presses.

How long does sheet piles take to install?

Generally, the cycle of excavation, old pile extraction and new pile installation for the 40 feet would take two to three days, depending on bottom conditions; obstructions could add significantly to that time.

Are sheet piles watertight?

On this basis, a steel sheet pile is watertight in all parts of its structure other than the part which needs to connect to other sheet piles – the interlock. Such interlocks are typically located at 600 to 800mm centres along the length of a steel sheet pile wall.

Are sheet piles permanent?

Sheet piling can be used to provide permanent foundations, permanent or temporary retaining walls and as extremely strong shuttering when a poured concrete foundation or retaining wall is required. Sheet piling can form the basis for an underground structure such as a basement or underground car park.

How long does steel sheet piling last?

A design life of 125 years is possible for permanently installed steel sheet piles but the age that a sheet pile wall can reach before needing replacement, will be dependent on the pre-protection built into the design, the type of project and the environmental, physical and weather conditions that the piles endure.

How deep can sheet piles go?

Combined sheet piling wall beam and pipe king piles are able to go deeper into dense soils than sheet piling sections of a contiguous wall — approximately 6.5 feet (2 meters) compared to 1.5 feet (0.5 meters).

How do you drive sheet piles into the ground?

Pressing method of sheet pile installation Using the pressing method, sheet piles are driven into the ground by using a hydraulic pressing method that jacks the piles into the required location. This method is based on each pile using the previously installed one’s reaction force, to push the pile into the ground.
