Vertical Impermeable Barriers (Cutoff Walls)

The three main types of slurry walls are soil-bentonite, cement-bentonite, and soil-cement-bentonite (see sections 2.1.1-3 for specifics). Depending on which type, the backfill may contain a mixture of bentonite, other clays, cement, fly ash, groundblasted furnace slag, among others (Pearlman, 1999).

USA Practice Slurry Wall Specifications 10 Years Later

Ten years earlier the authors prepared a paper on the then beginning state of practice regarding slurry wall specification in the USA. Changes (or lack thereof) and developments in the basic building blocks of specification criteria for the two types of walls constructed by the slurry wall technique; i.e., structural diaphragm walls and cutoff walls are reviewed.

Cement-bentonite (CB) cutoff walls have long been used to control ground water flow and contaminant migration at polluted sites. Hydraulic conductivity and unconfined compressive strength are two short-term properties often used by industry and owners in CB specification and are important parameters discussed in this paper. For polluted sites, long-term compatibility is also an important issue.
