Preventative treatment: Petrofix coating allows installation of pipeline through contaminated zone, Germany

A new underground pipeline was required to be installed across a complex chemical plant in southwestern Germany. It was found that part of the pipeline would intersect an area of soil and groundwater impacted with petroleum hydrocarbons and BTEX compounds.

Case Study Highlights:

• Total Petroleum Hydrocarbons and BTEX contamination, up to approx. 10,000 mg/kg
• Topical application of PetroFix onto the excavation base and sides to prevent the occurrence of recontamination
• The combination of sorption and biological degradation results in long term protection of the pipeline and avoidance of potential contaminant migration into and along the pipe bedding
• Results: Monitoring showed that there was 94% less petroleum hydrocarbons in MW-1 compared to MW-2
