New technology aids environmental remediation in low permeability soils

US-based EOS Remediation and geotechnical construction engineering firm Hayward Baker have formed a strategic alliance with Japanese company Chemical Grouting to launch a new remediation solution.

BioJet, which has taken eight years to develop, uses high pressure jetting tools and geotechnical analysis to create “intimate contact” between the engineered remediation products and the contaminants, according to the alliance.

The alliance has said that treatment time is minimised and contaminant rebound is eliminated by “cutting” circular slots in the soil and allowing effective distribution of the remediation products throughout the low permeability soils.

EOS Remediation president Ann Borden said: “It took a lot of work by a lot of people in the US and Japan to develop this safe and effective way to address back-diffusion issues characteristic of low permeability soils. BioJet sets a new and higher standard for treating a variety of contaminants in difficult lithology.”
