"Concrete Structural Surgery" is a four-page, full-color brochure describing Brown & Root's unique method of repairing and strengthening old, weak offshore platforms. The Houston-based subsidiary of the Halliburton Company has joined forces with cementing experts at Halliburton. A newly-formulated, super-strength, non-shrinkable grouting material is pumped into weak platform piles and cross members, to make them as strong or stronger than the original.
