Geophysical surveys

September 26, 2019

Geophysical surveys include the implementation of geophysical methods to indirectly determine the geological and structural as well as the physical and mechanical characteristics of the foundation soil. These methods are used to determine the layout, thickness and properties of individual layers below the terrain surface, on which the construction of a specific structure is planned. […]

Cone Penetration Test with pore water pressure measurement (CPTU)

Cone Penetration Test with pore water pressure measurement (CPTU)

June 13, 2019

A cone penetration test with pore water pressure measurement, or CPTU, is a static penetration test with water pressure measurement. The main purpose of CPT (CPTU) testing is to identify subsurface conditions: classify soil, detect layers and measure strength, determine deformation characteristics and the permeability of foundation soils. This is done mainly on the basis […]

3D geological model

3D geological model

May 3, 2019

In order to increase the quality of project documentation through more detailed preparation, gets insight into potentially problematic situations, and other technical solutions we create 3D geological models. What is a 3D geological model? A 3D geological model represents a spatial view of the foundation soil structure in the observed area. It is used as […]

Point load test (PLT)

Point load test (PLT)

February 7, 2019

The Point load test is an index test by which the rock is classified according to the strength. The test can be used to estimate other characteristics of intact rocks with which it correlates, such as uniaxial compressive and tensile strength. The test determines the strength index values at a point (Is (50)) and the […]

How to determine the age of a rock?

How to determine the age of a rock?

October 29, 2018

The age of a rock is determined by stratigraphy, a branch in geology which studies the chronology of events and changes, along with the development of organisms, which have determined the development of the Earth from when it became an independent spatial body until today. The age, or the chronology of geological creations and events […]

How to build on unstable terrains and avoid landslides?

How to build on unstable terrains and avoid landslides?

September 27, 2018

How to avoid landslides? In today’s blog, we present you examples of good practice in building structures on potentially unstable slopes. The temperatures are falling, the autumn is in front of us and we are expecting soon, wanting or not, the rainy periods that will actualize the subject in geotechnical engineering – LANDSLIDES. We have […]

Light dynamic penetrometer (DPL)

Light dynamic penetrometer (DPL)

September 6, 2018

About light dynamic penetrometer Light dynamic penetrometer (DPL) is used for testing the thickness of different soil layers, control of soil density or consistency and determination of strength and deformation parameters. In general, if the ground is not too dense or consistant, penetration tests can be carried out to depths of about 8 to 12 […]

Permeability test – Lugeon test

Permeability test – Lugeon test

July 26, 2018

Why we need permeability test? Permeability test is necessary on terrain where are predicted soakaways which store water after big rainfall and provide efficient soil infiltration. Usually they are used in areas where surface run-off cannot be disposed into existing sewers or watercourses. A Soakaway is constructed in one of two basic forms: Conventional soakaway […]

Exploratory drilling

Exploratory drilling

June 29, 2018

Exploratory drilling represents common underground research methods in geotechnical investigation works. It provides visual insight into the geological and geotechnical profile of the explored site. The most important result of the exploratory drilling is the drilling core that represents the depth profile of the studied position. In the way of performance, we differentiate the following […]

How to determine number and depth of exploration boreholes?

April 27, 2018

Number and depth of exploration boreholes   Like we have written in previous blogs, exploration works, geotechnical exploration works are an important part of each project. Unquality and unprofessional exploration works can lead to structural damage and costly and difficult remediation.   The position and depth of exploration and investigation has to be selected based […]

Dynamic plate – ideal tool for determining soil constrained modulus

Dynamic plate – ideal tool for determining soil constrained modulus

February 23, 2018

Dynamic plate For the beginning, let us consider a hypothetical scenario. A building has been constructed, e.g. a business warehouse. The new owner has begun noticing cracks in the walls and even a light-leaning of the building after a certain time. The problems are probably large settlements of soil under the building’s foundations. In that […]
