FIELD: chemistry.
SUBSTANCE: group of inventions relates to formation of coatings for reinforcement of rough stone or concrete surfaces, for instance stone structure in mines. Method of reinforcing rough stone or concrete surface includes stages at which solidified foamy composition is applied on at least part of the surface, with foamy composition containing mixture of polyisocyanate component and polyol component; foamy composition is at least partially solidified to form foamy layer, with at least part of foamy layer being attached to surface; solidifiable reinforcing composition is applied on at least part of foamy layer, with reinforcing composition containing polyisocyanate component and polyamine component; reinforcing composition is at least partially solidified to form reinforcing layer, with at least part of reinforcing layer being attached to foamy layer.
EFFECT: reduction of water leak or gas leak through cracks and hollow spaces in rock, efficient reinforcement of cracks and hollow spaces.
