Georadar
A georadar is equipment whose operation is based on the principles of radar, by emitting pulses of electromagnetic waves into a probed environment, the equipment records the time after which the response signals were received. Objects of various shapes and sizes, boundaries of layers in the ground or other environment under study, places with increased or reduced humidity, cracked or contaminated areas can serve as the reason for the reflection of signals – i.e. any places that differ from the enveloping environment by their electrophysical properties. The effectiveness of the georadar method depends primarily on the characteristics of the environment under study.
GEORADAR




With the help of a georadar, it is possible to productively study most of the natural and artificial environments, applying it in geological, archaeological research, survey of building structures, quality control of road and railway surfaces, search for underground communications and other objects. As a result of probing, a continuous cross-section of the environment is obtained in the appearance of a radarogram, which is analyzed by a specialist-interpreter using special software.
Universal application, accessibility for research purposes and speed of realization, since 21. At the beginning of the century, it is put forward as a leader among shallow geophysical research methods.
The main advantages of using a georadar are comparative economic advantage, sensitivity to the studied environment, speed of realization and high resolution.
Specialists of the company “SV solutions” perform both the above-mentioned works (see areas of application of the Georadar), as well as consult and perform other work with the georadar at the request of the customer.
GEORADAR – GEOLOGICAL SURVEYS


One of the most important tasks that arise in geology when a geological survey of any scale is to be carried out is to scan the bottom. Successful preliminary soil scanning allows you to concentrate work only in prospective areas, and the development of the soil is carried out only where the performed soil scan has provided an accurate, positive forecast. How can such a prediction be obtained? The answer is simple – if you need to scan the primer, you need to use a georadar – a device with which it is possible to implement the radar method. With the help of a georadar, it is possible to solve such tasks as mapping of geological structures and drawing up geological cuts, differences in the speed of propagation of electromagnetic waves, detection of karst and suffocating voids, mineral exploration, identification of the depth of water bodies and the profile of the bed, as well as engineering geological studies for construction purposes, etc.
GEORADAR – HORIZONTALLY DIRECTED DRILLING
Under the asphalt and sidewalks of roads there are many communications, the placement schemes of which are often lost or damaged. Therefore, before starting drilling work, it is imperative to clarify the real location of these communications, as well as make sure that there are no architectural monuments at the drilling site, especially if the works are carried out in the historical part of the city!
In the technology of horizontally directed drilling works, the application of a georadar allows you to choose the correct direction of movement of the drill. According to the information obtained by the georadar, the operator of the aggregate, varying the course of the drill in straight and inclined directions, can successfully bypass the obstacles identified under the bottom.
Due to this, the georadar ensures the obtaining of the desired result without interrupting the movement of transport and pedestrians, without damaging the wonderful urban landscape and without creating unnecessary construction debris.
Especially promising is the use of a georadar in horizontally directed drilling in urban conditions, so as not to damage ecologically and archaeologically valuable objects.

Production of environmental, sculptural objects and mock-ups
Design and manufacture of interior design objects
Road research and design
Study of ground and hydrogeological conditions in the track variation strip;
Determination of groundwater status;
Assessment of the contours and depth of the watershed bed at the site of the subsequent bridge passage;
Determination of the place and relative dimensions of the placement of engineering communications;

Quality control during the performance of construction, reconstruction and repair works of motorways
Evaluation of the quality of the creation of the earth’s surface;
Assessment of the thickness of the layers of the newly constructed road blanket;
Evaluation of the sealing quality and humidity of the laid materials.
If the road has obvious defects, then you no longer need to use the georadar – it is time to start replacing the pavement. As a preventive measure, an expert examination should be carried out with the help of a georadar. In this case, the georadar will not only protect the road from complete wear and tear, but also save funds for its restoration.
As a result of scanning roads and railways with a georadar, radarograms are obtained. According to radarogram data, the interpreter of the georadar data determines the boundaries of the bottom (base) and the state of the groundwater level. Against the background of research with a georadar, the design thicknesses of the constructive layers of the road blanket are often not observed. In addition, where the design thickness of the base layer is not observed, the thickness of the screed is necessarily increased during later repairs.


With the help of a georadar, it is also possible to detect such defects of the road surface
Grunts landing and bottom density reduction zones
Karst deformations
Virs ground and groundwater infiltration zones;
Nuniform, dusty and caked bottom areas
the spatial arrangement of the base of the S prost layer;
Wetand washed-out areas at the bottom base
Summing up the above about the georadar, let us note that at the moment the most accurate data on the condition of the road surface can be obtained by applying an economical, safe, reliable and non-destructive assessment method in which the georadar is applied.


GEORADAR – ARCHAEOLOGICAL INVESTIGATION
As a result of the application of the georadar, an opportunity has arisen to start a new stage in archaeology
If the georadar is applied in archaeology, then before the development of the bottom, geological scanning of a separate object can be carried out. By creating a network of profiles, with the help of a georadar, it is possible to survey large sections in detail. Due to this, it is possible to obtain a general cross-section of the terrain and track its possible development, separating the boundaries of the cultural and sedimentary layers. By conducting such studies, it is possible to detect buried valleys, dried up riverbeds and much more. By analyzing the general geophysical enterprise obtained with the help of a georadar, it is possible to plan the conduct of further archaeological work, clarifying the boundaries of ancient cities and settlements.
Detailed reception of the cultural layer with the help of a georadar in order to later clarify the places of development of the object allows you to single out the most promising research sites, thereby reducing the amount of earthworks to be performed.
Taking into account the experience of applying a georadar, we made sure that many archaeological objects have characteristic signals on radarograms that allow you to find and recognize the objects in question, without digging up the bottom.
Survey of the watershed bed, as well as the subsequent search for objects in it.
In conclusion, it can certainly be argued that the application of the georadar significantly simplifies the work of archaeologists and provides a lot of additional useful information, which significantly saves time, money and the amount of work.
GEORADAR – MONITORING OF REINFORCED CONCRETE STRUCTURES
The georadar becomes an indispensable device for non-destructive surveying of reinforced concrete structures. With the help of a georadar, it is possible to determine the quality and internal condition of concrete structures (bridges, buildings, VPP), survey dams, protective walls, slippage areas and locations of engineering networks, as well as find fittings and survey the internal frame of concrete structures.
Particular attention, from the point of view of operational safety, is paid to reinforced concrete structures of buildings. Thanks to the application of the georadar, an opportunity has arisen to determine the safety of their operation, the state of deformation of buildings and engineering structures, the condition of the foundation and piles.
When carrying out inspections of reinforced concrete structures and structures, with the help of a georadar, a general scanning is carried out, the locations of fittings, pipelines and ties are determined.
Specialists of the company “SV solutions” perform the following types of work
Determinationof the quality and condition of ethon structures B
Finding metal and plastic pipes, cables
Localization of cavities
Evaluation of Pposts
Inspection of the condition and quality of architectural objects
Detection of erosion
Localization of lice
Determination of the current status of D ambushes and dams
Builders widely use the georadar for surveying concrete before cutting or drilling, allowing you to find pipelines, so the likelihood of accidents is excluded, as well as excessively high repair costs. Also, one cannot do without a georadar, carrying out the determination of the position of concrete fixtures and tethers, the depth of their laying. For the purpose of surveying a georadar, it is enough to access one, the most convenient and easily accessible side of the structure.
Civil engineers use the information obtained with the help of a georadar on the state of the protective layer of concrete to determine whether the reinforcement is sufficiently protected from environmental influences.
The georadar allows repair workers to save a lot of funds, continue the production process, but most importantly – quickly and qualitatively solve their tasks.


GEORADAR – IDENTIFICATION AND SURVEY OF COMMUNICATIONS
Questions constantly arise about the need to engage in inspections of city communications. The amount of work like that is huge. The high cost of the solutions associated with it is also appropriate. In solving similar issues, specialists can be helped by a georadar.
Currently, the detection and survey of city communications with the help of a georadar is gaining deserved popularity. This is explained by the fact that by applying the georadar it is possible to conduct a search in very difficult urban conditions, which are characterized by a high level of electromagnetic interference, significant saturation and complexity of communications.
It should also not be forgotten that often the existing communication schemes and plans differ very significantly from reality, but sometimes it happens that they are lost altogether. In this case, it is not recommended to work without conducting a preliminary survey with the help of a georadar, since the georadar allows you to avoid inevitable crashes.
First of all, with the help of a georadar, it is possible to obtain all the necessary data to create a real picture of the location of communications. An experienced georadar operator with minimal reliability of error will get information about the spatial arrangement and integrity of the communication line.
Secondly , by applying a georadar, it is possible to find hard-to-find plastic, concrete and other non-metallic pipes.
If the georadar is used by communal repair services, then it is used to determine the location and depth of retracted hidden communications (for example, power and signal cables), to study the surrounding areas before carrying out earthworks, as well as to detect the places of de-hermetization of pipelines.
By applying the georadar, it is possible to successfully search for places of leakage of liquids flowing through underground pipelines, places of retraction of pipes and cables, detect damage to cables and cathode protection lines. If it is necessary to find cable tracks, then with the help of a georadar it is possible to find hidden wiring, which is located both under voltage and without.
WITH THE HELP OF A GEORADAR, IT IS POSSIBLE TO
detect metal and non-metallic objects, voids, and even small heterogeneous places;
find out the locations of gas and oil pipelines, as well as unauthorized connections to pipelines;
to determine the condition and location of underground reservoirs and pipelines connected to them;
detect sources of soil moistening, leaks from water pipes, collectors, hidden places of water lowering;
atrast plastic, metal pipes and cables, as well as determine the depth of their retraction;
detect and survey hidden septic systems, tanks, barrels, voids, filtration fields, etc.;
perform mapping of hidden communications of any complexity and length.
The application of a georadar to solve all the tasks listed above will simplify the technological process, save funds and reduce the time for completing relevant tasks.
