Have you ever wondered how geotechnical experts stabilize unstable soil and structures? Injection grouting is one of the key techniques we use at GSI to strengthen foundations, fill voids, and reinforce slopes. This specialized process involves injecting grout material into the ground to improve soil properties, increase load-bearing capacity, and mitigate settlement. Check out this video of one of our injection grouting projects to see how it’s done in action! You’ll get a closer look at the precision, expertise, and technology involved in delivering lasting stability solutions.

Before any excavation begins, STRATA engineers meticulously mark our test pit explorations. Following this, we promptly contact Idaho Digline to identify and mark any public utilities on site. Whether the excavations are borings, test pits, or rock probes, safeguarding against accidental strikes on public utilities is paramount to prevent service disruptions and injuries. #GeotechnicalEngineering #ExcavationSafety #ConstructionSafety #STRATA #EngineeringExcellence

How to Inspect a Hydrodynamic Separator The inspection includes proper measuring of sediment levels. Additionally, 2 stage units always use a diversion manhole. The diversion manhole needs to be opened and the screen checked for excessive debris. There are other instances where you might find a diverter. Reference the SWQMP drawings for verification. Additionally, the in and out drains in the diversion manhole need to be free and clear of debris.

UNDERWATER TUNNELS: COMBINED SUPPORT SYSTEM FOR COMPLEX TERRAIN The development of underwater tunnels presents unique and more complex challenges, where the geological classification of the terrain is essential to ensure safety and stability. Depending on the type of bedrock, different excavation methods are used. These methods determine the stabilization system. In terrains with crystalline rocks, where drilling and blasting (D&B) are commonly used for advancement, a combined ground stabilization system is required. A combined support system includes: ✅ Bolts: provide immediate reinforcement and improve the cohesion of the rock mass. ✅ Steel Frames: offer support by distributing loads evenly. ✅ Shotcrete: reinforces the tunnel walls with a protective layer. ✅ Invert Lining: ensures the stability of the tunnel base. Here we present an illustration of support for poor rock masses using spiling. It shows an example of combined pouring with shotcrete ribs and concrete invert (IGN, 2015). 👇 The success in the construction of underwater tunnels depends on geotechnical knowledge and the appropriate support systems. This combination guarantees the safety and efficiency of underground operations. ☝️For example, Norway has extensive experience in the development of tunnels for the petroleum industry, such as the Oslofjord, Bornlafjord, and Eiksund tunnels. At Onix Underground, we drive innovation in the industry, and we understand that safety is fundamental, as is efficiency. That is why each product in our brochure incorporates the latest technologies to ensure optimal performance, reliability, and resilience under extreme conditions.

Cable percussion drilling is an excellent technique for friction pile design, slope stability analysis, and for sites which have a significant probability of Made Ground (landfill sites, dockyards, infilled basements etc). Cable percussion (or Shell and Auger) drilling is suitable for a wide range of applications within clay, sand and gravel deposits as well as made ground, but will not advance through hard strata easily (rock, concrete etc). The technique allows sampling and in-situ testing to be undertaken, including undisturbed (UT100) samples, bulk (B) samples, SPT tests and in-situ vane tests. Because the size of the bore can be reduced during drilling, the technique is perfect if you need to 'seal out' contamination from upper horizons, to prevent polluting the natural ground below. #cablepercussiondrilling #shellandauger #shellandaugerdrilling #geotechnical #geotechnicalsiteinvestigation #geotehnicalinvestigation #piledesign #contamaintion #contamiantedland #contamaintedlandinvestigation #dockyard #madeground #landfill #buriedobstructions

At GTA, our Drillers are specialists in advanced subsurface exploration and well installations using two techniques: 🔹 Hollow Stem Auger (HSA) Method: How It Works: This tool features a helical screw blade with a hollow central core. It drills through unconsolidated soils and sediments while allowing for continuous soil sampling and minimal disturbance. Benefits: Provides stable borehole support and accurate soil profiles, ideal for site assessments and environmental studies. 🔹 Mud Rotary Method: How It Works: Combines rotary drilling with a drilling fluid (mud) to cut through various soil and rock types. It’s perfect for drilling deeper boreholes. Benefits: Effective for a wide range of ground conditions, offering cooling, lubrication, and efficient cutting removal. Both methods are essential for effective subsurface exploration and well installation, tailored to meet the needs of different ground conditions and project requirements. #GeoTechnologyAssociates #EnvironmentalConsulting #GeotechnicalEngineering #GeotechnicalServices #ConstructionServices #EnvironmentalServices #DrillingServices #GeoTechnical #Engineers #Construction

Blue skies, sunshine and a bit of warmth...it's been a while! ☀ We were making the most of the conditions during this project, which was a hybrid of a ground investigation and preliminary assessments for potential water wells. Ground conditions across the vast site were challenging in some parts due to soft and uneven terrain, so one our low ground pressure (LGP) Hycat drill rigs was on hand to make tracking between borehole locations that bit easier. #geotechnical #groundinvestigation #waterwell #boreholes
