The gel-push sampling technique was developed to try to provide an economic technique capable of obtaining high quality specimens of silty sands and sands. This paper describes two of the gel-push samplers which are now commercially available and describes their performance on recent projects carried out on soils in New Zealand with reference to field measurements of shear wave velocity.
