Impact-drilled RD piles are pipe piles that can be drilled through any ground types using a top or DTH hammer. Impact-drilled RD piles are a popular piling option in the rocky ground of the Scandinavian countries. A suitable drill bit pulls the pipe in when drilling. Pipe elements with a length of 3–6 m are connected by sleeves or welding, and filled with concrete.
