Problems arise when erecting a sheet pile on rock substratum and subsequently anchoring the piles. If a channel is blasted, this has the draw-back that the over burden has to be initially cleared prior to blasting and then replaced subsequently. In addition, the piles when secured in the blasted channel when refilled with concrete and the anchors in the rock substratum are not as securely supported as piles driven into normal substratum. A method of erecting sheet pile and a method of anchoring the sheet pile is disclosed where the substratum is shattered by blasting sufficiently to allow the piles and the anchors, which are also piles, to be driven into the rock substratum. Each method involves drilling bore holes and inserting a water tight charged container into these and determining the volume of charge relative to container volume such that the rock substratum surrounding a bore hole after detonation is not significantly damaged in its external form but has a shattered internal structure allowing pile driving.
