Architecture and Properties of Geocomposite Materials with Polyurethane Binders
(Methods and Results of Laboratory and in situ Research at IGN AS CR)
The paper deals with architecture and properties of polyurethane geocomposites - specific materials created in the field of grouting technologies by pressure grouting of polyurethane resins into soils, disturbed rocks or into damaged building structures. A long-term systematic research on grouting processes, properties of chemical grouts and geocomposite materials is realized at the Institute of Geonics of the Academy of Sciences of the Czech Republic. This subject represents one of crucial trends in the research carried out there. The new findings achieved in laboratories of the Institute of Geonics in this research area during the last 5 years are summarized in the paper.
