Types of shallow foundations

July 25, 2019

Shallow foundation Foundation depth usually involves depth, measured from the terrain surface, to the base surface through which the foundation transfers the structure load to the soil. According to Eurocode, shallow foundations are considered to be bases whose width is greater than the depth of foundation (D <B). Shallow foundation is applied in cases where […]

Differential settlements

Differential settlements

April 26, 2019

Settlement of the foundation structures is a problem that people have faced ever since they first started constructing. The size of a foundation structure settlement is primarily dependent on the weight of the structure and the deformation characteristics of foundation soil. When analyzing this problem, it is necessary to distinguish between the concepts of uniform […]

Material replacement under foundation

Material replacement under foundation

February 28, 2019

What is material replacement? Material replacement is the process of removing the existing and installing materials with better properties which are achieved by controlled installation. This is one of the most common foundation soil improvement processes applied when low soil physical and mechanical properties are present under the foundation. The purpose of the material replacement […]

Soil liquefaction

Soil liquefaction

February 22, 2019

Local soil conditions have a significant effect on damage to structures caused by earthquakes. During an earthquake, different kinds of soil conduct generated seismic waves in different ways and their effect on structures depends on the characteristics of the foundation soil. Many earthquakes, such as those that occurred in Japan in 1964 (Niigata) and in […]

Use od spectral analysis of surface waves (SASW) for foundation soil improvement quality control

December 20, 2018

What is foundation soil improvement? Soil improvement includes a range of compaction and mixing technologies of the existing and new soil in which the natural soil transforms into a new material. Using soil improvement methods, it is possible to increase the soil load bearing capacity, reduce or keep under control total and differential settlements, reduce […]

Foundation soil improvement of the Zaprešić – Zabok railway line R201

November 23, 2018

The company Geotech Ltd. is a part of the project that includes modernization of the Zaprešić-Zabok railway line R201. This is a section of the Zagorje line, leading to Čakovec with a regional character (R201 Zaprešić – Bedekovčina – Čakovec) and plays an important role in passenger transport in the area of Zagreb agglomeration. For […]

Pile integrity test

Pile integrity test

August 2, 2018

What is pile integrity test? Pile integrity test covers the procedure for determining the integrity of individual vertical or inclined piles by measuring and analyzing the velocity (required) and force (optional) response of the pile induced by an (hand held hammer or other similar type) impact device usually applied axially and perpendicularly to the pile […]

Geotechnical exploration, investigation and foundation remediation for a former Croatian post office building in Rijeka A reconstruction and conversion of a former Croatian post office building in the street Korzo, in Rijeka, is currently underway. The Croatian post office building, the so-called Main post, was built in 1887. as an administrative-business building of the Royal […]

Foundation remediation with jet grouting

Foundation remediation with jet grouting

March 19, 2018

Jet grouting   Jet grouting is one of the technologies of foundation remediation. Foundation remediation of the buildings that are in function is very complex and it is necessary to adjust the technology to the conditions on site.   Jet grouting is a soil improvement method that converts a certain volume of soil into a […]

Foudation remediation by using expanding geopolymers

Foudation remediation by using expanding geopolymers

March 2, 2018

Expanding geopolymers   Deep injection of expanding geopolymers is a relatively new and innovative way of solving foundation settlement problem. The original idea comes from Scandinavia, where the first experiments were made in 1975.   The method is based on the principle that a special expanding geopolymer is injected underneath the foundation with a pressure […]

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 […]

Former industrial complex Rikard Benčić – from tobacco factory to a cultural district

February 19, 2018

Geotechnical exploration and investigation and foundation design for Rikard Benčić In 1851, the production of tobacco started in an existing building of the old Sugar Refinery. At that time, it served as administrative building for the tobacco factory, and then as an engine factory “Rikard Benčić”. The complex was expanded by a historicist four-story building […]

Foundation remediation technologies – When? Why? How?   Whether you are an investor, an architect, a structural engineer, a supervising engineer or a designer, if you are interested in this subject you have probably come across this kind of problem. When the need for foundation remediation appears it is probably due to occurred unaccepted total […]

Jet grouting – verification of the design requirements

January 24, 2018

Soil improvement method: Jet grouting Jet grouting is a soil improvement method that converts a certain volume of soil into a mortar, breaking down the soil structure using high energy fluid jets. The normal pressure used for jet grouting is approximately 500 bars, and the injection speed is about 300 m / s (1080 km […]

Foundation design of the garage beside Hotel Adriatic in Opatija – a combination of shallow foundations and deep foundations

January 9, 2018

Foundation design of the garage   As part of the existing hotel Adriatic in Opatija, it is necessary to extend the parking capacity and it was decided to build a multi-story parking building (G + 3 floors) at the back of the hotel.   The location of the future garage is located on the southern […]
