Abstract

A method of making on site, a ground anchor comprising an anchor element (9) having a corrosion proof sleeve (1) secured to an end portion of the element, comprises locating a number of lengths of the sleeve (1) about the end portion of the element (9), applying a cap (11) to the end of the sleeve, and supplying a self-setting composition via the cap into an annular clearance (15) between the sleeve (1) and the element (9). The cap (11) may be left in place to seal the end of the anchor and to protect the anchor during insertion into a borehole. The sleeve (1) preferably comprises an outer layer of plastics, an intermediante layer of set filler and an inner layer of metal. The invention includes the sleeved anchor element and the sleeve lengths themselves.
