THE FOUNDATION SOIL IMPROVEMENT USING EXPANDABLE RESIN

Abstract

The foundation soil is an inevitable factor in the stability of a building and should be viewed as a separate entity that requires a detailed characterization and assessment of the geotechnical circumstances at individual locations. Through the exploitation of buildings, we witness changes in the geomechanical characteristics of the soil as a result of secondary influences characterized by climate change, the presence of sanitary and storm water, vibrations in urban areas and earthquakes. All the mentioned occurrences result in the settlement of bearing parts, and thus endanger the structural parts of buildings. In the world of geotechnics, for the past few years we have witnessed the affirmation of the Deep Injections method, which is used for rehabilitation, but also for improving the foundation soil of existing buildings using expandable resins.
