Projects
A selection of underground detection and geotechnical investigation projects completed across Saudi Arabia.
GPR Survey & Root Cause Investigation
2km pavement collapse adjacent to the Riyadh Metro Blue Line flyover. GPR, trial pits, and root cause analysis identifying metro vibration and adjacent excavation as the cause, followed by grouting remediation.
View Full Case Study →Illegal Tire Landfill Mapping
75,000 m² site with 35 years of buried tire waste. GPR revealed three distinct tire layers at 3m, 6m, and 12m depth, each confirmed by mechanical trial excavation.
View Full Case Study →Guardrail Post Integrity Testing
550 guardrail posts tested with dynamic impulse analysis ahead of the Six Flags Qiddiya opening, verifying embedment depth and structural soundness in just 7 days.
View Full Case Study →Riyadh Metro Corridor Utility Survey
Client: Construction Contractor
Challenge: Identify all existing utilities along a 2.4km road corridor prior to excavation for transit infrastructure works, avoiding any disruption to live electrical and telecom services.
Methodology: Combined GPR and electromagnetic detection survey conducted in 50m grid sections, cross-validated with available municipal utility records.
Equipment: GPR, EM Locator, Radio Detection, GPS Survey
Deliverables: CAD utility map, GIS dataset, written survey report
Outcome: Zero utility strikes recorded during subsequent excavation works.
Industrial Facility Leak Detection — Jubail
Client: Petrochemical Operator
Challenge: Locate the source of unexplained water loss across an underground firefighting pipeline network spanning the facility.
Methodology: Acoustic correlator survey conducted across accessible pipeline sections, supplemented by ground microphone point surveys at suspected leak zones.
Equipment: Acoustic Sensors, Ground Microphones, Correlator
Deliverables: Leak location report with GPS coordinates and repair recommendations
Outcome: Leak isolated to a single joint failure, repaired within 48 hours of report delivery.
Residential Tower Geotechnical Investigation — Jeddah
Client: Real Estate Developer
Challenge: Determine soil bearing capacity and foundation recommendations for a proposed 22-story residential tower on a coastal site.
Methodology: Six boreholes drilled to 25m depth with SPT testing at 1.5m intervals, undisturbed sampling, and full laboratory testing program.
Equipment: Rotary Drilling Rig, SPT Equipment, Laboratory Testing
Deliverables: Geotechnical engineering report with foundation design recommendations
Outcome: Pile foundation design finalized using investigation data, avoiding costly over-design.
