The range of chemical grout uses in civil and underground engineering has increased rapidly, along with requirements on special sealing and reinforcing grouting technologies with high target parameters. Connecting demands of knowledge of grout properties and behaviour during grouting process and after curing are necessary for the design and control of the grouting technologies. In the past, the laboratory research on grouts was mainly directed at concrete mixtures. Recently, the laboratory testing methods for chemical grouts have been developed; the methods are often different, and the chemical grouts used have different properties. The paper deals with methods used and developed in the laboratories of the Institute of Geonics in Ostrava, Czech Republic, and present the results of laboratory tests connecting to wellknown projects in the C2ech Repuvlic (e. g. underground gas storage Hdje).
