GROUND ENGINEERING & GEO-SYNTHETIC SYSTEM
A - GROUND ENGINEERING
In Strong Force-MGC, we know that we are in the era of coupling and integrations among all the fields. The structural designs are no more disconnected from ground engineering as they are coupled for a better understanding of the complete soil-structure interactions. Hence, and equipped with high-end and advanced Geotechnical tools (such 3D finite element modelling software: PLAXIS3D among others), we provide the most economical, safe, and innovative practical solutions to our clients and partners in success. We provide design & built of buried pipes analyses, cavity filling, cut-off walls, dewatering and waterproofing solutions, engineering alternatives, foundations and pavement solutions, Geo-environmental solutions, Geotechnical evaluation, ground anchors, micropiles, numerical & FEM modelling, piled post-tensioned raft foundations, rock bolts, slope protection, soil improvement, soil nails, soil-water-structure interactions analyses, underpinning and upgrading of foundations and many more. We support our clients from site explorations and investigations stage and till the execution of the most optimized Geotechnical-Structural solution by our skillful and passionate researchers, engineers and technicians.
1. Micropiles, Post-Tensioned Raft, Micropiled Post-Tensioned Raft
The micropiles are considered as vibration-free deep foundation elements that are used extensively for underpinning, strengthening, upgrading, slope stability, offshore, sensitive structures, and inaccessible site applications and as well as in the structural foundation system. The raft foundation is usually adopted to overcome the differential settlement issues. The post-tensioning of the raft allows increasing its stiffness and reduce the thickness and the steel reinforcement required for the raft. However, when found on soft or compressible soil, the raft will experience an undesirable behavior. Therefore, and before heading to the conventional piling system, the micropiled raft system is proposed. Depends on the project and site’s geology, the micropiles will act either as a settlement reducer or a capacity upgrader under the raft. Unlike the conventional piling system, the imposed loads are shared between the micropiles and raft. Such a system has proven its effectiveness in many projects such as warehouses, schools, institutes, hospitals, towers, residential buildings, showrooms, villas, housing projects, malls, car parks, bridges, offshore structures, etc. Nevertheless, this requires a comprehensive evaluation and understanding of the soil-raft-micropile interactions. Our skilled and highly experienced engineers carry out these analysis and evaluationS. The advanced and high-end analyses allow us to install the micropiles at their optimum locations as needed, resulting in a value engineering solution. Both, the post-tension raft and micropiled post-tensioned raft, were successfully completed by Strong Force-MGC for different project in Bahrain, on a design-and-build basis.
2. Ground Improvement:
Strong Force-MGC is supporting its clients from the very initial stages by planning, advising, and evaluating the soil investigation program of the site’s subsurface strata. When the subsurface soil in a project’s site is considered problematic (e.g., debris-mixed soils, expansive/swelling clay, liquefiable soils, contaminated soils, cavities, carbonated soils, etc.), it needs to be remedied, treated, and improved. The conventional treatment by the excavate-remove-replace method is considered a time-consuming and costly process. Therefore, we are supporting our clients by conducting the most viable option for ground improvement with our various improvement methods such as chemical treatment, jet grouting, cavity filling, compaction grouting, grout columns, geosynthetics reinforcement, recycled materials utilization, among others. We do consider the cost, safety, and time to meet and exceed our clients’ expectations.
3. Cut-Off Wall
For the projects near shorelines and below the water table such as basements, deep excavations, tunnels, shafts, and alike, the water seepage is a significant issue that will increase the risk, cost of dewatering & waterproofing, and the project duration. In such a situation, the cut-off wall can be used as a cost-saving and effective solution to control the seepage of the water, enhance the dewatering efficiency, contribute to stability, and to insulate the potential leakage sources from the proposed structure. The cut-off wall material and procedure is tailored to satisfy the site conditions and project specifications.
4. Slope Stabilization and Shotcrete
For excavations, cuts, and slopes in soil and rock; the stability against different failure modes (such as sliding, slipping, wedge failure, toppling, rock falls, etc.) has to be ensured. Therefore, Strong Force-MGC performs a thorough analysis and design to maintain the stability of the project and will propose the most economical solution to satisfy the stability requirements. The stability measures taken by Strong Force-MGC might involve Shotcrete, Geo-Netting, Soil Nails, Rock Bolts, Ground Anchors, Micropiles, Geotextiles, among others. Proudly, we have installed ground anchors for several deep excavation projects and completed rock-cut stability works in the southern part of Bahrain.
B - GEOSYNTHETICS
We are the official distributor and provider/installer of high-quality European geosynthetics. All of our Geosynthetics products are available and customizable as per your project requirements and specifications. Some of which are shown below:
- Geobags: it is produced from the stitching of high strength woven geotextile fabric. The geotextile bags are filled with soil or sand, and they are used for flood control and shoreline & slope protection.
- Geocells: They are widely used in construction for erosion control, soil stabilization on flat ground and steep slopes, channel protection, and structural reinforcement for load support and earth retention. They are made with ultrasonically welded high-density polyethylene (HDPE) strips or novel polymeric alloy (NPA)—and expanded on-site to form a honeycomb-like structure—and filled with sand, soil, rock, gravel or concrete.
- Geocomposites: They combine the best features of different materials in such a way that specific applications are addressed in an optimal manner and at minimum cost. For instance, they can be Geotextile-geonet composites ( for separation and filtration applications), Geotextile-geomembrane composites (for drainage applications), Geomembrane-geogrid composites (as high-strength impervious barriers), and many more.
- Geofoam: It is expanded polystyrene (EPS) or extruded polystyrene (XPS) and usually used as lightweight fill for embankment, retaining walls, and soft soils.
- Geogrids: It is geosynthetic material used to reinforce soils and similar materials. Geogrids are commonly used to reinforce retaining walls, as well as subbases or subsoils below roads or structures. They are also used for pavement reinforcement to enhance pavement performance and reduce the pavement thickness.
- Geomembranes: It is a very low permeability synthetic membrane liner or barrier used with any geotechnical engineering related material to control fluid (or gas) migration in a human-made project, structure, or system.
- Geomembranes: It is a very low permeability synthetic membrane liner or barrier used with any geotechnical engineering related material to control fluid (or gas) migration in a human-made project, structure, or system.
- Geonets: It is a geosynthetic material similar in structure to a geogrid, consisting of integrally connected parallel sets of ribs overlying similar sets at various angles for in-plane drainage of liquids or gases. It is also used in capillary stopping applications.
- Geosynthetic clay liners (GCL): It is a factory-manufactured hydraulic barrier consisting of a layer of bentonite supported by geotextiles and/or geomembranes, mechanically held together by needling, stitching, or chemical adhesives. It is an economic hydraulic barrier and used in the waterproofing and environmental containment applications for canals, tunnels, basements, and others.
- Geotextiles: They are permeable fabrics which, when used in association with soil, have the ability to separate, filter, reinforce, protect, or drain.
- Geo-Mesh Netting: Usually, it is a hexagonal-shaped and a UV resistant that is used for slope stability, retaining structures, and erosion control applications.
