Riyadh · Jeddah · Dammam · Jubail — excavation shoring, basements and port marine works.
As a specialist sheet piling contractor Saudi Arabia infrastructure clients rely on, EG Core delivers engineered earth retention and cofferdam systems for commercial, industrial, marine and utility projects across the Kingdom. Our scope covers temporary and permanent sheet pile walls, combi-walls and king-post systems installed with high-frequency vibratory hammers, silent hydraulic press-in rigs and impact drivers matched to soil conditions and site sensitivity. From deep basements in Riyadh commercial districts to jetty upgrades in Jubail and Ras Al Khair, we combine ArcelorMittal and ThyssenKrupp hot-rolled sections with Giken, PVE, ICE, Movax and Junttan driving equipment to achieve verticality, penetration and watertightness in strict accordance with EN 12063, EN 1997 Eurocode 7 and Saudi Building Code SBC 303.
Every deployment begins with a full review of the geotechnical investigation, groundwater profile and adjacent structure survey, followed by section selection, driveability analysis and installation method statements sealed by our in-house geotechnical engineers. Our field crews operate across Jeddah, Dammam, Khobar, Yanbu and remote industrial sites, executing dewatering, excavation, waling and anchor works under continuous instrumentation and monitoring. As a sheet piling contractor Saudi Arabia developers select for high-risk excavations, EG Core prioritises schedule certainty, low-vibration methods near live assets and full traceability of steel grade, section modulus and driven length for permanent record and Eurocode compliance.
Hot-rolled U-profile sheet piles from ArcelorMittal and ThyssenKrupp, interlocked on the neutral axis for cofferdams, basement walls and temporary retention in cohesive and mixed soils typical of Riyadh and Dammam sites.
Z-profile sheet piles with interlocks on the outer flanges deliver superior section modulus per metre of wall, ideal for deep basements, underpasses and permanent retaining walls where bending capacity governs the design.
Combined walls pairing tubular king piles with intermediate Z or U sheet piles provide extreme stiffness for quay walls, deep cofferdams and marine berths in Jubail, Yanbu and Ras Al Khair port developments.
Soldier pile and lagging systems using driven or bored H-section king posts with timber or precast concrete infill panels, suited to dry granular sites and phased excavations where full watertightness is not required.
PVE, ICE and Movax high-frequency variable-moment vibrators install sheet piles rapidly in sands, gravels and soft cohesive soils while controlling ground vibrations transmitted to neighbouring commercial and industrial assets.
Giken Silent Piler press-in machines install sheet piles by static hydraulic reaction, eliminating vibration and noise for work next to operating refineries, hospitals, metro tunnels and heritage structures across the Kingdom.

Our geotechnical engineers analyse the site investigation, groundwater regime and surcharge loads to develop the retaining wall concept and preliminary embedment depths.
Section profile, steel grade and length are selected against bending, shear and driveability criteria using ArcelorMittal and ThyssenKrupp product catalogues.
The pile line is set out by total station and a steel guide frame is fixed at working level to control alignment and pitch of the first pair of piles.
The lead pile is pitched into the guide frame, plumbed in both axes with digital inclinometers and locked to establish the reference for the panel.
Piles are driven to the design toe level using PVE, ICE, Movax or Giken equipment selected for soil resistance, proximity constraints and permitted vibration limits.
Steel walings, hydraulic props or post-tensioned ground anchors are installed at each design level to transfer lateral loads before further excavation proceeds.
Excavation advances in controlled lifts with wellpoint or deep well dewatering while inclinometers, piezometers and survey targets confirm wall performance against predictions.
On temporary works, piles are extracted with high-frequency vibrators, inspected, straightened where required and returned to stock for redeployment on future contracts.
Our chartered geotechnical engineers deliver full temporary works design to Eurocode 7 and SBC 303. Every wall is analysed for bending, deflection, base heave and hydraulic stability before mobilisation.
We operate high-frequency vibrators, impact hammers and Giken Silent Piler press-in rigs. This lets us select the correct method for soil, vibration limits and proximity to sensitive assets on every project.
Crews and equipment deploy rapidly to Riyadh, Jeddah, Dammam, Khobar, Jubail, Yanbu and Ras Al Khair. Our logistics team handles heavy transport permits and remote camp setup for industrial sites.
Direct procurement relationships with ArcelorMittal and ThyssenKrupp secure hot-rolled sections in required grades and lengths. Mill certificates accompany every delivery for full traceability.
We execute jetty, quay and cofferdam works from jack-up barges and land plant alike. Combi-walls and tubular king piles are installed to port authority specifications in the Arabian Gulf and Red Sea.
Inclinometers, piezometers, load cells and automated total stations track wall behaviour in real time. Data is reviewed daily against trigger levels agreed with the designer and client.
