Soil Bentonite Walls:

Soil Bentonite and Cement Bentonite walls by DeWind One-Pass Trenching are revolutionizing the Slurry Wall industry! Now there is a cost-effective mixed in place technology that completely homogenizes all of the soils and bentonite from TOP to BOTTOM in a continuous linear wall from beginning to end. With this continuous mixing process there is virtually no possibility for windows or voids in the wall. Each wall is evenly and consistently mixed from top to bottom and from start to finish.


DeWind has developed a number of custom attachments and quality control features for our One-Pass Trenchers to ensure a perfect wall every time regardless of changing soil conditions. The Trenchers are equipped with metered bentonite delivery systems, underground water injection nozzles, pre-mixed slurry injection ports, speed controls for both the mixing chain and track speeds, GPS mapping and laser guides to control depth.


Engineers who use the DeWind One-Pass Mixed-In-Place method prefer it to the conventional excavator installation methods because of the completely homogenized soils from top to bottom, secure key into confining layer, no possibility for voids in the wall, precise laser installations, no messing mixing ponds, ability to work in tight sites, no open excavation and super fast installation rates with a precise mapping of the alignment for future use.
