by:GeoSierra LLC - a Cascade Company based inNorcross, GEORGIA (US) (USA)
GeoSierra's azimuth controlled injection technology has been used to construct full scale iron permeable reactive barriers (PRBs) from moderate depths (~50 ft bgs) down to significant depth (>180 ft bgs). The injection technology constructs the iron treatment wall from a series of conventionally drilled boreholes along the prescribed wall alignment, with ...
Manufactured by:DeWind One-Pass Trenching LLC based inZeeland, MICHIGAN (USA)
All One-Pass Trenching operations are performed under the water table in highly fluid soils. On contaminated sites… the One-Pass Technology has no equal. ZVI, Zeolite, Active Carbon, Mulch and any other reactive materials can be easily installed in a continuous wall to depths of up to 40’ feet deep. The seamless One-Pass operation cuts a precise trench and simultaneously backfills ...
by:Heijmans Blackwell Remediation Ltd based inEssex, UNITED KINGDOM
A PRB is an engineered in situ treatment zone of reactive media. When installed in the flow path of contaminated ground water, PRB's can remove contaminants as it passes through a more permeable 'reactive' section. Lower permeability barrier sections, essentially cut off walls, can be used to direct ground water through the ...

by:Mersino Dewatering Inc. - a Mersino Company based inDavison, MICHIGAN (USA)
A permeable reactive barrier (PRB), also referred to as a permeable reactive treatment zone (PRTZ) or Bio-Wall, has been recognized as being a cost-effective technology for in-situ (at the site) groundwater remediation. Depending on your groundwater flow control needs, our one-pass trencher can install both slurry walls and permeable ...
by:GeoSierra LLC - a Cascade Company based inNorcross, GEORGIA (US) (USA)
GeoSierra has pioneered the installation of trenchless subsurface permeable reactive barriers (PRBs) for groundwater remediation and has installed kilometers of PRBs at sites throughout the USA. The same technology is used to create a subsurface impermeable barrier, as a freeze wall, or impermeable by grout injection or the injection of a special ...

by:InSitu Remediation Services Limited (IRSL) based inBurlington, ONTARIO (CANADA)
Reducing time and cost with innovative integrated approaches. Most remediation projects require the use of a suite of approaches in order to meet the remedial objectives for the site. Most technologies have limitations and struggle with the removal of the last 5–10% of the contaminant mass within the aquifer. Yet, most projects require the removal of > 99% of the contaminant mass in ...
