Excavator mixing is the simplest form of soil mixing and can be used to mechanically mix cement or other additives with soil in-situ. This method is often used for stabilization and solidification of contaminated soils on sites where the contamination is contained within the upper ~20’.
Excavator, a.k.a. bucket mixing, is generally performed with conventional excavators and buckets, but can be performed with excavators fitted with long sticks and/or specialty buckets. Specialty buckets used for bucket mixing are designed to improve mixing efficiency and might include rakes, holes or screens.
This technique offers a cost effective and schedule efficient solution that can be applied to problems on many sites, depending on the improvement objectives and treatment depth.
