Steel sheetpiles are popular due to:

Ø          strength

Ø          ease of handling

Ø          ease of construction

Ø          potential for reuse

Lengths may be mixed within a wall, but sheet piles should be ordered from a single source because interlocks vary by manufacturer.  Steel sheetpiles are generally shipped and driven in pairs.

Applications:  

Sheetpiles are used for the construction of retaining walls, temporary shoring, cofferdams, docks, jetties, bridge abutments, flood and ocean protection, cut-off walls, and more. Sheetpiles compete for shoring applications with beam and plate or beam and lagging (treated wood, steel, sheets or shotcrete), soil nails, tiebacks (washers), secant piles, contiguous piles, trench boxes, crib walls, and retaining walls.

However, sheetpiles excel in wet environments. Uses for steel sheetpiles fall into two categories:

Temporary applications of steel sheetpiles:

Ø          basement to a building

Ø          retaining walls to exclude earth and/or water

Ø          construction of the pile cap for a pier in the river

Ø          prevent slides and cave-ins in trenches

Permanent applications of steel sheetpiles:

Ø          basements

Ø          underground car parks

Ø          waterfront structures

Ø          landfill and waste disposal

Ø          foundations

Ø          beach erosion protection

Ø          cofferdams

Ø          stabilizing ground slopes

Ø          pump house below grade

Advantages of steel sheetpile walls:

Ø           positive trench wall support

Ø          controls groundwater effectively

Ø          can be extracted and used many times

Ø          minimum right of way required

Ø          allows maximum access

Ø          fast in loose soils

Ø          satisfies "extraction of temporary works" requirement

Ø          excavation / backfill quantities minimized
