Abstract
The invention relates to a process for the reinforcement of anchoring pilings used particularly in the oil-drilling industry, where a tubular steel piling (1) is driven into the ocean floor. Successive injections of a grout which can harden are made into the ground (7) which is contained inside the piling.
