FIELD: chemistry.
SUBSTANCE: invention relates to backfill compositions used in the oil and gas industry in sealing production casings and cement sheath, when detaching strata, when sealing water inflow and lost circulation control. The backfill composition contains the following in wt %: an queous solution of an alkali metal silicate - 30-40, sodium silicofluoride - 60-70. In another version, the backfill composition contains the following in wt %: an queous solution of an alkali metal silicate - 30-40, sodium silicofluoride - 60-70, filler - solid zeolite-containing wastes - the rest.
EFFECT: improved waterproofing properties of the backfill composition due to improvement of its strength and adhesion properties.
