Abstract
A method of anchoring an anchor element in a borehole comprises supplying self-setting composition into a sleeve while withdrawing the sleeve so that the self-setting composition fills the annular clearance between the element and the wall of the hole. Preferably the element is first secured within the hole by a self-setting resinous composition and, in order to provide additional corrosion protection for the element, the end portion of the element has a precast sleeve, and a plastics sheath is heat-shrunk on to the remaining portion of the element.
