Execution of special geotechnical works — In-Situ Soil Mixing; German version EN 14679:2026
Abstract
This document specifies general principles for the execution, supervision, inspection, testing, monitoring and maintenance of in situ soil mixing works (Deep Mixing) carried out by two different methods: dry mixing and wet mixing. Soil mixing considered in this document is limited to methods which involve: — mixing by rotating mechanical mixing tools, including jetting and/or compressed air assistance, where the lateral support provided by the surrounding ground is not removed; — different shapes and configurations of soilmix elements, either columns, panels, walls or any combination of more than one single element, with or without overlapping; — treatment of soils and fills, including brownfields, sludges, etc., with possible limited penetration into the rock; — mass mixing; — environmental mixing, involving installation of containment and permeable reactive barriers and solidification/stabilization of contaminated soils and sludges. This document does not apply to shallow soil stabilization, which consists of granulating the surface soil and mixing it with binder using stabilizing machines to improve performance. Shallow soil stabilization is in the scope of EN 16907 4.
