From field studies to planning the extent of subgrade reinforcement
Each study begins with a field study of the target area, in which continuous sets of samples are taken from fine-grained sediment layers. The sample series are analysed to identify the typical characteristics of the geological depositional environment, which must be considered in the construction planning and environmental impact management.
The samples from the field study are analysed according to the customer’s needs. In addition, GTK can prepare a 3D model of the stratigraphy and distribution of fine-grained sediments in the area.
Sample series that extend through the fine-grained sediment layers enable a comprehensive analysis of the soil layers.
By conducting site-specific laboratory studies, GTK can obtain detailed information on the location and properties of both soft and dense clay deposits, which facilitates the planning of the scope and material needs of subgrade reinforcements.
Moreover, the customer will learn what kinds of clay layers exist at different depths, which makes it easier to anticipate the amount of surplus soil, for example. Furthermore, knowledge of the different layers and their distribution enhances the targeting of further geotechnical studies.
