Static probing

STATIC PROBING

The most frequently performed engineering method of geological research in Lithuania (field testing)  is static probing, sometimes called simply CPT (Cone Penetration Testing). Testing with a cone penetrometer (CPT) or with a pore pressure measuring head (CPTU) is also one of the most economical and sufficiently accurate testing methods for assessing the information obtained on soil properties, amount, water form and condition in soils and time. Geoengineering is your reliable partner if you need a building probing service.

In order to determine the boundaries of the soil layers, the type of soil, its strength properties, a probe with a cone-shaped nozzle is hydraulically pressed into the soil by rods. During the probing of the structure, electronic stress gauges are used, which not only allow the accurate measurement of the physical properties of the soil, but also to systematize all the data obtained and form them into a single stratigraphic record. According to the European standard ISO 22476-1: 2012 valid in Lithuania, the probe readings are recorded every 1-2 cm. Such a methodology allows not only to achieve maximum results, obtain relevant information, but also to protect the test site from major destruction of the foundation, as well as from unwanted products formed during drilling, which can become harmful to humans and the environment.

Depending on geological conditions, soils and their strength, the depth of the static probing test can reach more than 60 meters, but under Lithuanian soil conditions (gravelly and gravelly fluvioglacial and alluvial soils, very compact moraine clays and dust) usually reach only 20-25m or even much shallower depth.

WHEN IS STATIC PROBING NEEDED?

Cone penetrometer (static probing) testing for buildings of various complexity, roads, railways, tunnels, viaducts is an indispensable source of information - design research can help prevent future problems, reduce costs and avoid additional, unplanned investments. Building probing provides valuable information for the construction of wind turbine towers, overhead power line supports, other engineering structures and multi-purpose buildings.

WHY IS THE STATIC PROBING METHOD ONE OF THE BEST?

  • static probing makes it possible to obtain a continuous stratigraphy of the soil base;
  • this method can be used to examine even the thinnest soil layers and sublayers;
  • static probing is independent of weather conditions so the test can be performed in any weather - the progress of the work or the results will not be affected;
  • all soil layers are tested safely in accordance with the requirements without endangering the physical and mechanical properties of the soil and the environment;
  • the testing completely avoids the generation of hazardous waste, so static probing is environmentally friendly and complies with all environmental principles;
  • compared to other analogous methods, static probing is more precise (in data collection and analysis) and takes much less time – up to 2-3 times;
  • static probing is relevant for environmental and geotechnical research.

ADVANTAGES OF STATIC PROBING COMPARED TO ALTERNATIVE METHODS

The static probing method is superior to alternatives such as conventional drilling in terms of the impact on the soil, time and cost. Static probing is characterized by its versatility and mobility, which means that it can be carried out both on land (even in hard-to-reach places) and in water (from ships, lifting platforms, etc.).

The data obtained during static probing is very accurate, received and processed quickly, includes a wealth of data collection points, and thus provides a comprehensive set of information.

Compared to alternative conventional soil drilling studies, static probing is much superior (2-5 times) in terms of time.

The innovative, advanced technology used by our team allows geologists and engineers to obtain detailed, accurate and useful information about the soil.

Static probing is a soil testing methodology characterized by its speed, versatility, safety and accuracy, as well as great benefits in determining the mechanical properties of the soil.

  • Building probing and other services are performed using modern equipment, which allows us to speed up work processes and obtain optimal results.
  • We provide services in Lithuania and neighboring countries.
  • We offer flexible terms for all our clients.
  • We are trusted by state and municipal institutions, construction companies and transport infrastructure companies, design and architecture offices, various development companies, agricultural companies and private individuals, among others.

OTHER SERVICES PROVIDED BY GEO ENGINEERING:

  • Soil drilling. The method allows us to accurately identify and study the soil and its mechanical and physical properties, boundary layers and other significant aspects.
  • Dynamic probing. A method that proves itself in the design of roads, railways, viaducts and other communications. This is a rapid field study that is recommended to be combined with other field studies for optimal, accurate, and reliable results.
  • Soil laboratory tests. Indispensable when it comes to studying the physical and mechanical properties of a soil, its composition, type, strength, and many other aspects.
  • Soil compaction control. A method to assess the degree and quality of soil compaction is necessary for the design of transport networks and any other structures.
  • Static and dynamic plate tests. Static plate testing determines exactly what the strength of the soil, the quality of compaction and the risk of deformation under load are, and the use of a dynamic plate allows you to quickly determine the quality of soil compaction.
  • Excavation and description of pits. This field research method provides an opportunity to study the foundations of the old building and the soil underneath it, to take good quality soil samples, which is relevant when planning reconstruction or new construction in the countries.
