Fremgangsmåte og apparat for utgravning av koesivt mater- iale som omfatter å rette en fluidstråle, f.eks. vann, mot en skjæreflate til materialet og langs spor plassert fra hveran- dre for å skjære adskilt spor og derved å skape et snitt mellom de to sporene. Oppfinnelsen er spesielt anvendelig for utgravningen av grøfter som underjordiske kabler og rør legges i.
