French term

injection par passe remontante

French to English Tech/Engineering Engineering: Industrial land remediation techniques
"L'injection se fait par passe remontante, manchette par manchette à l'aide d'obturateur gonflable double."

This is in a description of a project where land polluted with mercure was reclaimed by injecting a special substance that immobilised the pollutant so that it stayed in place, without penetrating into groundwaters.

Thank you in advance
