Cleaning of the tank with pressure washer, plus sandblasting for the complete opening of the porosities present, and restoration of total impermeability by closure and remediation of the widest and deepest cracks. For those with a thickness of less than 0.4 mm, the procedure with Penetron grouting was used (indicated for the in-depth waterproofing and chemical protection of any concrete structure).
