Earth Retention & Shoring

Sheet Pile Shoring

Pacific Foundation installs steel sheet pile walls for excavation support, cofferdams, temporary or permanent earth retention, and water-control-adjacent work.

The fit comes down to driveability, groundwater, vibration limits, wall support, access, and what has to happen inside the excavation next.

Continuous Wall Interlocking steel sections create a continuous wall for earth retention, excavation support, and cutoff applications.
Excavation Support Cantilevered, anchored, or internally braced systems can support temporary or permanent excavations where the ground and wall design fit the method.
Water-Control Interface Sheet pile can reduce seepage into an excavation, but interlocks, embedment, bottom conditions, penetrations, and the dewatering plan still matter.
Installation + Extraction Temporary sheets can often be extracted after the permanent work is complete when access, adjacent construction, ground response, and the installed condition allow.
Method Fit

Where Sheet Pile Fits

Method selection · 01–04

Sheet pile works best when a continuous driven wall matches the ground, access, vibration limits, excavation geometry, and water-control objectives.

01

Temporary Excavation Support

Utility structures, pits, foundations, and below-grade work where a continuous wall can be installed before excavation and supported as the cut advances.

02

Cofferdams and Wet Excavations

Waterfront, bridge, utility, and civil work where sheet pile forms the perimeter of the work area and may help reduce groundwater or surface-water inflow.

03

Constrained Wall Lines

Sites where the shoring system has to stay close to the excavation and a driven wall can fit the available setup and pile-handling area.

04

Permanent Wall Applications

Sheet piles can remain as part of the completed work where the design, corrosion protection, cutoff elevations, and finished condition call for a permanent wall.

Field Conditions

What Controls the Work

A sheet-pile callout on the plans does not mean the installation is automatic. The wall still has to reach embedment, stay on alignment, fit the support system, and work with the rest of the excavation.

Ground and Obstructions

Dense fill, cobbles, boulders, buried concrete, hard layers, or shallow rock can slow or stop penetration. Driveability needs to be understood before production assumptions are carried into the bid.

Vibration and Adjacent Structures

Vibratory installation transfers energy into the ground. Nearby structures, utilities, active facilities, vibration-sensitive equipment, and sensitive soils can change the installation method or make another shoring system more practical.

Groundwater

Sheet-pile interlocks can reduce seepage, but the wall should not be treated as automatically watertight. Toe conditions, interlocks, penetrations, bottom stability, and the dewatering or bottom-seal plan all affect the excavation.

Embedment and Wall Support

Retained height, surcharge, soil, groundwater, and movement criteria determine whether the wall can cantilever or requires tiebacks, walers, struts, deadmen, or another designed support system.

Access and Pile Handling

Sheet length, crane reach, leader or hammer geometry, overhead clearance, laydown area, working-platform capacity, and access along the wall line all affect the field setup.

Extraction and Turnover

Temporary sheets still need an exit plan. Extraction has to be coordinated with the permanent work, backfill, neighboring structures, access, and acceptable ground movement.

Construction Sequence

The Wall Is Only the Start

Sheet-pile installation has to stay coordinated with excavation, wall support, groundwater control, and the structure being built inside the shored area.

  1. Layout and setup

    Confirm wall line, utilities, access, guide conditions, pile handling, and installation equipment.

  2. Install the wall

    Advance sheets to the required line and embedment using the approved installation method.

  3. Start excavation

    Excavate to the elevation allowed by the wall design.

  4. Install support

    Add walers, tiebacks, struts, rakers, or other designed support at the required stage.

  5. Continue excavation

    Advance excavation and groundwater control in the required sequence.

  6. Build permanent work

    Coordinate wall support and site access with the structure, utilities, or civil work inside the excavation.

  7. Complete the wall

    Extract, cut off, or retain the sheets as the design requires and site access allows.

Installation Equipment

Sheet Pile Equipment

Pacific reviews the soil conditions and specified sheets before choosing a hammer. The crew also needs room to lift and position each sheet along the wall. Vibration limits near existing structures may require a different installation method.

MKT V-1 Vibratory Hammer

Used for light sheet pile installation and extraction and smaller pile-driving scopes.

MKT V-5 Vibratory Hammer

Used for mid-size crane-hung sheet pile installation and removal.

View Equipment
APE Model 50 Vibratory Hammer

Used for sheet pile installation and extraction, temporary shoring removal, and marine or waterfront pile work.

View Equipment
ICE Model 416L Vibratory Hammer

Used for heavy sheet pile installation and extraction, cofferdam pile work, and larger temporary piling scopes.

System Selection

When Another Wall Fits Better

Sheet pile is one earth-retention method. Project conditions can make a drilled wall, soldier pile wall, or separately coordinated anchor and groundwater-control scope more practical.

Severe Vibration Restrictions

Where adjacent structures, utilities, equipment, or soils cannot tolerate expected installation vibration, a drilled shoring system may be more appropriate.

View Secant & Tangent Piles

Hard Ground or Obstructions

Frequent boulders, buried structures, hard layers, or shallow rock can create driveability and alignment risk.

View Soldier Pile Shoring

Tight Movement or Cutoff Criteria

Where wall stiffness, movement limits, or groundwater cutoff control the work, a stiffer drilled system or overlapping secant wall may fit better.

View Secant & Tangent Piles

Support Beyond the Wall

If the excavation requires anchors, tiebacks, dewatering, or another support system, those scopes have to stay coordinated with the wall and construction sequence.

Sheet Pile FAQs

Questions We Hear During Preconstruction

Can sheet pile control groundwater?

Sheet pile can reduce seepage because the interlocking sheets form a continuous wall, but it should not be assumed to be watertight. Interlocks, penetrations, embedment, soil conditions, bottom stability, and the dewatering or bottom-seal plan all affect groundwater performance.

What can make sheet pile a poor fit?

Hard layers, boulders, buried obstructions, severe vibration restrictions, limited pile-handling access, difficult wall alignment, or movement and groundwater criteria that exceed the selected system can make another shoring method more practical.

How is sheet pile different from soldier pile and lagging?

Sheet pile creates a continuous interlocking wall. Soldier pile walls use spaced vertical piles with lagging installed between them as excavation advances. Groundwater, vibration limits, obstructions, excavation sequence, movement criteria, access, and cost all affect which system fits the job.

Can sheet pile be used for temporary shoring and then removed?

Yes. Temporary sheet pile is commonly extracted, but removal has to be planned around access, adjacent construction, ground movement, backfill, and the condition of the sheets after installation.

Can sheet pile be used for deeper excavations?

Sheet-pile walls can be supported with tiebacks, walers, internal struts, deadmen, or other engineered systems. Excavation depth, ground, groundwater, surcharge, movement criteria, and available support geometry determine the design.

What does Pacific need to price a sheet-pile scope?

Send the wall layout and shoring drawings, excavation depth, geotechnical report, groundwater information, specified sheet section if available, bracing or tieback requirements, utilities, adjacent structures, vibration limits, access restrictions, temporary or permanent requirements, extraction assumptions, bid date, and construction schedule.
