This paper concerns two of the most widely used methods of groundwater control for construction in alluvial deposits, namely grouting and groundwater lowering. An adequate site investigation is imperative for their successful design, and the particular information required of the investigation is discussed.
The various techniques employed to stabilise a wide range of soils by these methods are described in outline, and examples are given. An appraisal is made of the two methods and their relative merits under various ground conditions.
