Services
We maintain professional licenses accredited in the UK, Canada, Australia, New Zealand & other Commonwealth Countries, Middle East, and USA. Our services help you to overcome geotechnical challenges to create new infrastructure and buildings. We provide a diverse range of assessments, interpretations and analyses of geotechnical data of the site. Our objective is to provide foundation design solutions which are innovative, cost effective and buildable for our clients adding value to projects. We provide a full range of geotechnical services:
1. Scoping of ground investigation
Scoping of ground investigation will be performed into several stages starting by Initial Desk Study of available data for the site, such as aerial photographs, geological and hydrogeological information, review of performance of existing adjacent structures to identify geotechnical hazards for site with problematic soils such as soft ground or Peat, gypsiferous soil/rock with cavities and sites with high groundwater level or tar springs
Uncommon ground conditions – Project Site with Tar Springs – Heet, Iraq
2. Interpretation of ground conditions
Data interpretation/analysis is used mainly for understanding ground conditions and selecting the most suitable foundations and/or soil improvement technique to achieve the improvements intent. And, to design soils improvement injection configuration, depth, selecting grout mix, injection pressures, stoppage criteria, etc.

Soil Replacement (Stone Columns)
-
Soil Densification (Vibro-Compaction )
-
Grouting (Soil Compaction & Permeation)
Compaction Grouting is used for soil densification, and liquefaction abatement, and for large cavity fill. Compaction Grouting consists of the injection of a low-slump (less than 50mm) soil cement grout under high pressure (1.2 –4 MPa) to compact and displace the adjacent soils. The grout does not penetrate soil pores but displaces the subsurface soils by forming a homogeneous bulb with its centre near the tip of the injection pipe

Soil Preloading and Consolidation - Wick Drains
Wick drains also known as Prefabricated Vertical Drains (PVD), and it work by promoting horizontal dissipation of excess pore pressures instead of vertical excess pore pressure flow in traditional 2D consolidation problems in clayey soils. Below figure presents the concept of soil consolidation techniques. In most cases, a surcharge applied to make the wick drains more effective.
4 - Micropiles, Tie Backs, and Tie Downs
Micropiles have been designed to achieve up to 500 tons or even more loads, and have been extensively used in upgrading existing buildings, and where there is limited access. Our team has designed, installed and tested many of them under different conditions, where access is extremely limited
Geotechnical Assessments
3. Earthwork Studies
4. Slope Stability Analysis
Carry out a static or dynamic, analytical or empirical method to evaluate the stability of fill, excavated/natural slopes and propose stabilization measures

9. Site Inspections
1. Foundation Design with Bearing Capacity and Settlements Values
2. Pile Design & Existing Pile Issues
3. Conventional and Segmental Retaining Wall Design
Verifying designs that were carried out by international consultants who have different design approaches/software’s and discuss criticality of various factors on electing the best supporting systems for deep excavations. The work accompanied by predicting ground movements with different ground water scenario’s due to local hydrogeological conditions and the high variations in permeability between different formation and the flow of groundwater in the respective interface, producing karstic voids and fissures at the limestone.

Determine the optimum ground improvement option.
The best improvement option will be determined considering site conditions, structure type, cost effectiveness and sustainability of the improvement option
2. Provide conceptual design, specifications and design criteria's of different ground improvement techniques such as:
Soil shallow mixing can be done by full soil replacement or to a selected lower ratio where all the soil inside a defined block is treated, as mass stabilization. Depth of this type of treatment limited to around 5m
The weak soil is penetrated by the aid of vibration and compressed air or water. At the required depth stone is discharged and compacted. By the continuous addition of stone, a dense column of stone constructed, which is tightly interlocked with the surrounding soil

3 - Seismic Upgrade of Existing Structures
Seismically up grading foundation soils for existing structures to current codes, to mitigate liquefaction and/ or lateral spreading, and reduce dynamic settlement
