Abstract: Sandy soil is stabilised by treatment with a combination of a film-forming polymer and a cement with a water-binding capacity of at least 50 wt% and/or an early strength value (after 12 hours) which is at least 30% of the final strength. A method for stabilising sandy soil (I) involves incorporating into the soil (i) a finely-divided, water-insoluble, film-forming polymer (P) with a minimum film-forming temperature (MFT) of not above 30[deg]C in amounts of 0.1-10 wt% based on the solid content of (I), and (ii) 0.5-10 wt% of cement with a water-binding capacity of at least 50 wt% and/or an early strength value (DIN EN 196-1; at 20[deg]C after 12 hours) which is at least 30% of the final strength.
