Abstract
A method for gravity grouting the annulus between a piling and a piling sleeve wherein air pressure is used to expel water and foreign matter from the annulus. Air pressure is then reduced in the annulus that is sealed at the top and has a seal at the bottom capable of holding a differential pressure between water pressure at depth and atmospheric air pressure within the annulus. Grouting material is then fed to the annulus between the piling and the sleeve and permitted to set.
