Protecting Concrete Tanks for Chemical Service: A Guide to Applying Polyurea Geomembranes

摘要

Design engineers and applicators are often laced with challenging liner or coatings installations for con-crete tanks or related structures in chemical other aggressive service. Often, the chal lcnge starts with the existing structural surface, which might be cont animated or require significant repair, resurfacing, or extensive surface preparation. When such surface conditions are not remediated completely, traditional liquid applied linings often fail because their performance depends directly on the surface to which they are applied. Coating systems may be also susceptible to chemical attack and may delaminate or blister, compromising their performance and the tank itself.
