LOW MOBILITY GROUTING

Nicholson Construction Company has the ground treatment techniques to meet the diverse challenges our customers face.  We draw on our experience and capabilities to produce high-quality and cost-effective solutions.

Nicholson utilizes low mobility grouting (LMG) in situations where the grout mix needs to have a very limited ability to travel from its point of injection.  These situations are common for grouting abandoned mines, karst solution cavities, and for water cutoff projects (also see asphalt grouting for water cutoffs). 

The means and methods for low mobility grouting are very similar to compaction grouting (a form of low mobility grouting) with the exception of a slightly higher slump range on the grout mixes. Also, injection rates are increased to > 2 cubic feet/minute due to typical open voids versus displacement of soils as with compaction grouting. 

In recent years, low mobility grouting has become desirable for the installation of micropiles in voided or highly fractured formations.  Using this technique, Nicholson provides both a deep foundation structural element while providing ground treatment at the same time by consolidation grouting the surrounding formation with low mobility grout.

Nicholson has the unmatched experience and value-added engineering capabilities to develop the most viable and cost-effective solution for the use of low mobility grouting techniques.
