Placement of the polymer enhanced foam in a desired treatment region of the soil produces a seal that substantially eliminates the permeability of the treatment region to the migratory fluid and prevents migration of fluid across the region. In each of its numerous embodiments, the process can be employed as either a remedial or a preventative treatment.Field of SearchOrganicChemical Impermeabilization Cement or consolidating material is organic or has organic ingredient Composition for plugging pores in wells or other subterranean formations; consolidating formations in wells or cementing a well or process of preparing Composition for treating unconsolidated or loose strata, e.g., sand consolidation, etc. Composition for in situ soil conditioning or treating or process of preparing | |
