Study Procedure
Electrodes are installed, which are integrated into the transmission and reception circuit in an automatic sequential way. One electrode at a time in sequential form constitutes the emission circuit and supplies direct current on the ground surface; the electric current circulates through the subsoil materials, creating an electric field whose potential is measured through the electrodes that constitute the receiving circuit. This sequence is intercalated between all the electrodes used.
The objective of the equipment used to obtain field data is to measure the differential mass resistivity of the ground, which is specially designed to perform measurements from 0.5 ohm-m to 9.999 ohm-m in 0.1 ohm-meter intervals. Subsequently, the information is processed, and the results are interpreted using software and mathematical models. The results of the vertical electrical probs are grouped together forming the Geoelectric profiles.
The Electric Resisitivity/Conductivity Survey that is employed by Geopile Engineering is mainly for aquafer (a.k.a. underground water) detection. Our high accuracy detection rates have proven in various projects with successful detection and water well drilling.

Micropiles, commonly referred to as “mini-piles,” are elements constructed using high-quality, durable, small-diameter steel casings or threaded bar. They’re most frequently used when installing a deep foundation. There are many reasons to use this pile type. Here are the most common reasons: To provide structural support To underpin your foundation To transfer loads To enhance mass stability This pile option will help you underpin your foundation, minimize foundation settlement, and are ideal when installing in areas with difficult soil makeup.
How Does the Micropile Installation Process Work? The first thing you need to do is dig a deep hole with a small diameter. Once you’ve cleared the space for the pile, you can lower that into the hole and apply torque to secure the pile. Then you fill the hole with a concrete grout mixture to keep everything in place. After you let the structure settle, you can apply a support system to the top of the pile. This will distribute weight evenly and guarantee good contact with the supported foundation.
What are the Benefits of Micropile?
This pile option is one of the most practical and cost-effective solutions. It offers easy installation with its compact, lightweight nature, and is great for confined or remote areas like steep slopes, basements, overpasses, and even river pier foundations and wetlands. It also can be installed at various angles and is capable of resisting axial and lateral loads. This option is ideal for rocky areas because they can be secured within the rock, and actually draw load bearing capabilities from it. It’s also more easily installed in congested areas, and since it’s installed vertically, it can be used for tight spaces that machines can’t get to. It’s great for situations when you actually need to repair your foundation. But its main benefit is that it’s durable and cost-effective and take far less time to install than other pile options.Foundations provide support for structures, transferring their load to layers of soil or rock that have sufficient bearing capacity and suitable settlement characteristics. Very broadly, foundations can be categorised as shallow foundations or deep foundations. Pile foundations are deep foundations. They are formed by long, slender, columnar elements typically made from steel or reinforced concrete or sometimes timber. A foundation is described as piled when its depth is more than three times its breadth. Micropiles are piles that have a relatively small diameter, typically in the range of 100-250 mm. They can also be described as: Minipiles (generally mini piles are smaller than micro piles) Pin piles. Needle piles. Root piles. Lightweight piles. The size of the pile is determined by the load-bearing capacity of the ground and the size of rig that is able to access the piling location. They can be driven or screw piles and tend to be used where access is restricted, for example underpinning structures affected by settlement. They were first used in Italy in the 1950s in response to the demand for innovative underpinning techniques that could be used for historic buildings and monuments. They are particularly suited to: Shallow bedrock. Boulders and cavities. Immediate hard strata. Where underpinning is required, such as for foundations adjacent to planned excavations. Micropiles can also be used in combination with other ground modification techniques where complex site conditions and design specifications are present. In a typical installation process a high-strength steel casing is drilled down to the design depth. A reinforcing bar is inserted and high-strength cement grout pumped into the casing. The casing may extend along the full length of the pile, or it may only extend along part of the length of the pile, with the reinforcing bar extending along the full length. Drilling may be achieved by a removable bit, or by a sacrificial head to the steel casing. In some cases, the steel casing may be removed, or partially removed, and further grout pumped in at pressure. They can be installed in restricted access sites where there is low headroom by the use of lagging. This is where wood, steel or precast concrete panels are inserted behind the pile as the excavation proceeds so as to resist the load of the retained soil and transfer it to the pile. Greater capacity can be achieved by post-grouting within the bond length to increase frictional forces with surrounding soils. There are advantages of micropiles include: They are small and relatively light. They are relatively inexpensive. They can be installed through almost any ground condition, making them suitable for installation in environmentally-challenging conditions, such as for wind turbine towers. The limited vibration and noise causes little disturbance. Piling rigs can be low-emission or even electrically driven. They can be installed while avoiding existing utilities, meaning that expensive utility re-routing is not required. They can beinstalled close to existing walls with limited headroom and congested site conditions. They have a high load capacity and an ability to resist compressive, tensile and lateral loads.
