Typical applications for this agent include the construction of diaphragm walls, foundations, pipe jacking, tunnelling, and so on. Modern chemical processes to modify the ionic surface of bentonite greatly intensify this stickiness, resulting in remarkably dough-like yet strong casting sand mixes that stand up to molten metal temperatures. However, in commercial and industrial applications, the term bentonite is used more generally to refer to any swelling clay composed mostly of smectite clay minerals, which includes montmorillonite. In sandy soils, bentonite clay (sodium montmorillonite) must be mixed with the drilling water to increase its viscosity and keep the borehole from collapsing (just a small amount of bentonite is required).

It is used to line the base of landfills to prevent migration of leachate, for confining metal pollutants of groundwater, and for the sealing of subsurface disposal systems for spent nuclear fuel. These characteristics of bentonite clay make it a strong option for the heavy metal ion reduction from bulk solution. Clays, especially bentonite, have high affinities for water, distribute themselves evenly throughout water, swell when they become wet and the reverse when they become dry, and have electrically active surfaces and high specific charges (charge/mass). How long does bentonite waterproofing last? The Bentonite continues to expand for about the next 30 days as it forms a high-performance watertight membrane against the structure. Its physical composition (high aggregate solids content and low permeability) makes it particularly well-suited to serve as a collar or "plug" around a pipe. A method used to increase driving depth is to utilize an oversized drive shoe, slightly opening the hole. A trench that would collapse due to the hydraulic pressure in the surrounding soil does not collapse as the slurry balances the hydraulic pressure. Sodium activation is performed to convert calcium bentonite to sodium bentonite, in which calcium ions are exchanged for sodium carbonate.
