The history of sheet piling goes back to the beginning of the last century. Over the years, ongoing development in steel grades, section shapes ans driving techniques have led to a wide range of applications for sheet piling. The applications include securing excavation, waterfront structures, foundations, bridge abutments, noise abatement walls, highway structures, cuttings, landfill and contaminated ground enclosures, and flood protection schemes. The main engineering advantages of sheet pile walls over other types of wall are:
- • The extremely favourable ratio of steel cross-section to moment of resistance
- • Their suitability for almost all soil types
- • Their suitability for use in water
- • The fast progress on site
- • The ability to carry loads immediately
- • The option of extracting and reusing the sections
- • Their easy combination with other rolled sections
- • The options of staggered embedment depths
- • The low water permeability, if necessary using sealed interlocks
- • There is no need of excavations.
