Originally developed in the 1950s, soil mixing really took off in the United States in the late 1980s to early 1990s. Today, it is a widely used means of creating a stable structural foundation while reducing the environmental impact construction may have on the surrounding areas. The ultimate goal of every soil mixing project is to create a more stable soil with improved properties relative to the existing soil.
How Soil Mixing Works
There are three main types of in situ soil mixing: deep soil mixing, shallow soil mixing, and backhoe stabilization. In all of these processes, a soil mixing auger will penetrate the soil and then a fluid grout will be added to the soil to help create a type of soil-cement. These materials added to the soil, or reagents, will vary depending on the project and the design mix service, but they may comprise bentonite, blast furnace slag, cement kiln dust, or other such materials.
In Situ Soil Mixing Uses in Construction
The applications for in situ soil mixing have increased dramatically over the past few decades. Common uses include being used to stabilize, solidify, and treat for improved seismic shear resistance and leachability reduction. This commonly takes the form of creating structural foundations and retaining walls. However, newer applications include introducing specialized cements to treat hazardous waste, provide environmental site remediation, stabilize sludge and lagoons, and groundwater containment and treatment.
The Environmental Advantages of In Situ Soil Mixing
This expansion into environmental stabilization and protection has made in situ soil mixing a valuable choice over alternative forms of soil mixing that often have greater environmental repercussions. Environmental contaminants represent a major concern in construction. Fortunately, certain reagents, including special clays, oxidants, and other reactive media can be introduced into in situ soil by using deep and shallow soil mixing techniques to help treat and contain the harmful components in the soil within the soil mixing wall. By using certain reagents, contractors can render harmful chemicals in the soil less damaging or even inert, particularly through oxidization.
Contractors and Construction Services for In Situ Soil Mixing
From design mix services to project completion, there are many contractors able to provide design support and construction services. Contractors will provide owners and engineers with the specialized equipment needed to perform the specific tasks involved in soil mixing. They can also provide additional support as needed, including project planning, design assistance, and other geotechnical services. The parameters of every project vary both by soil composition as well as by the ultimate construction goals for the building or containment site.
In addition to identifying the type of in situ soil mixing needed, geotechnical contractors can also identify alternative projects or construction techniques that may be more suited to a particular environment or task. This could include building a soil mixing wall, collection trenches, grouting services, and slurry walls. To identify the needs of your particular project, consult with a geotechnical contractor while drawing up plans for your project.
