Abstract

A method of de-watering a slurry mixture produced from a jet grouting operation, comprising the addition to the mixture of an anionic polyacrylamide in such manner that it is uniformly distributed therein, the anionic polyacrylamide having a high molecular weight and a low-medium charge density. Dewatering is achieved readily and economically.
