Wax Protection for Ground Anchors

In this paper, the author describes why grease cannot guarantee long-term protection against corrosion for ground anchors, why wax is a better solution, and the benefits of changing from grease to wax protection. These products are used mainly for foundations and to secure construction, but also can be used for a variety of additional geotechnical applications. Specific topics covered include metal soaps (petroleum greases), petroleum wax, stability under heat and de-oiling, long term behavior of these products in water or moisture, their long term behavior in an alkaline environment, corrosion protection in electrolytic solutions, wax for strand anchors, and cost considerations. The author discusses three noteworthy case histories. The author concludes that there is always the possibility of water having access to the high strength steel of the anchor tendon. After good quality control in the production and construction arenas, it is vital to incorporate protective materials into the goal of corrosion prevention. The better behavior of petrolatum (wax) observed in the tests coincides with the practical experience gained from buried steel pipelines.
