Services
Thrust boring and pipeline services: directional drilling, micro tunnelling, Direct Pipe, auger boring, vacuum excavation, piling, dewatering, vertical drilling and field joint coating.
Micro tunnelling
Laser-guided tunnel boring for 1,000 to 2,800 mm pipe, holding precise gradients below the water table at up to 3 bar face pressure.
- Pipe size
- 1,000 mm to 2,800 mm ID
- Drive length
- 20 m to 700+ m
- Face pressure
- Up to 3.0 bar
Direct Pipe
Pre-fabricated steel pipelines of 30" to 56" pushed into the ground while it is excavated, in one step, over drives of up to 1,200 m.
- Pipe size
- 30" to 56"
- Drive length
- Up to 1,200 m
- Ground
- Soft, medium and rock
Auger boring
Cost-effective jacked casing crossings of 12" to 48" under railways, roads and structures.
- Pipe size
- 12" to 48"
- Bore length
- 20 m to 150 m
- Ground
- Soft and medium
Vacuum excavation
Exposing buried services by suction, with no mechanical contact, so cables and pipes are not damaged.
- Excavation rate
- Up to 10 m³ per hour
- Material size
- Up to 250 mm
- Reach

Concrete and steel piling
Sheet pile walls and bored piles for deep excavations, launch and reception pits.
- Methods
- Steel sheet piling, bored concrete piles
- Installation
- Impact and vibratory hammers, piling rigs
- Use
- Shoring of deep excavations and pits
Dewatering
Lowering groundwater before excavation so pits, foundations and trenches stay dry and stable.
- Equipment
- Submersible and centrifugal pumps, eductors, well points
- Use
- Foundations, shoring, pits and cellars
Vertical drilling and cathodic protection
Water wells, geothermal boreholes and deep anode wells for cathodic protection. Approved by Saudi Aramco.
