Applying aluminum-organic matter precipitates to reduce soil permeability in-situ: A field and modeling study

Using naturally occurring processes to modify the engineering properties of the subsurface has received increasing attention from industry and research communities as they aid in the development of cost-effective, robust and sustainable engineering technologies. In line with this trend, we propose to use precipitates of aluminum (Al) and organic...

Direct Injection of Aluminum-Organic Matter Flocs to Reduce Soil Permeability and Create a Vertical Flow Barrier in Situ

This study presents a novel geotechnical engineering approach that utilizes naturally occurring processes to reduce soil permeability in-situ. This approach is inspired by a soil stratification process (Podzolization), where a low permeability layer is formed by metal-organic matter precipitates. In a field experiment, a direct aluminum...
