1234 effective in wet conditions. Compared to Innocoat 1080, the crust is more brittle and less elastic. Control samples with lime milk show the following limitations: • Easy peeling of the surface in wind; • Short effect (up to 24–48 hours); • Requirement for daily treatment; • High solution costs (~14 L/m²); • Instability in humid or rainy conditions. Field tests were carried out in an emergency depot. For the repeated tests, an area (5x5 m) of the emergency depot was prepared. The surface was cleaned of lime milk. Within this area, 9 squares with an area of 1x1 m were defined, treated with equal amounts – 2.5 L/m2 – of the reagents, with different concentrations of the solutions. Reagents: Innocoat 1080, Innocoat 1038, Innocoat 1090 were applied with the corresponding concentration: 1 wt.%, 3 wt.%, 5 wt. Figure 3 - Test section of an emergency fayalite landfill. Table 3 shows the success rate of “sealing” of the treated surfaces, observed during testing with a strong jet of pressurized air. The time for qualitative drying of the surfaces after wetting with the solutions from treatment to testing is 13 days.
