Interaction Between Sandy Deposits and Multimolecular Organic Solutions by Stabilisation of Soil / Saveika Tarp Smelio Nuosedu Ir Daugiamolekuliu Organiniu Tirpalu Stabilizuojant Grunta

The paper presents the state of the art in grouting technologies for underpinning of old foundations, the analysis of grouting with multimolecular organic solutions and the results of investigations of dispersive soils stabilised with organic polymers over a period of one year. It describes the comparison between properties of unmodified carbamide resins and properties of modified carbamide resins. The following properties of resin solutions were investigated: density, viscosity, pH (alkalinity level) and evaporation of components from solution. The next stage of investigations involved the comparison of properties of alluvial medium dense sand stabilised with unmodified and modified resins.
