Advancements in subsurface barrier wall technology

Subsurface barrier walls are enjoying a resurgence in popularity as components of site remediation systems largely for two reasons. First, treatment technologies have shown themselves to be incapable of fully managing a large proportion of waste disposal sites, especially large landfills, DNAPL sites, and large industrial plant sites, thus underscoring the importance of site-wide containment technologies such as subsurface barrier walls. The second factor is a parallel advancement in the technologies of barrier wall construction. Advancements, include a variety of geomembrane-based barrier walls, jet grouting techniques, deep soil mixing, and the ability to construct deep barrier walls (greater than 150 feet deep) using interlocking plastic concrete panels. These advancements have led to barrier walls which are not only more impervious, more resistant to chemical attack, and capable of achieving greater depths, but in many cases are less costly than earlier technologies.
