自世纪之交以来，冷藏设施中保持在0°C（32°F）或更低温度的地板已发生弯曲和隆起。此类设施中的地板被广泛破坏，许多系统已被用于尝试防止新设施中出现此类重物。在地板已经弯曲的现有设施中，使用了几种方法来减轻重量。地面隆起的问题并没有得到普遍解决，因为大多数方法要么被不加区别地使用，要么施药者不了解他使用的方法中涉及的原理。一旦设施建成，如果防止底鼓的方法不充分且安装不当，那么在地板实际发生底鼓后纠正错误不仅困难、成本高昂，而且耗时，即使安装了防止此类底鼓的系统。 问题似乎一直摆在我们面前:“在设计和建造的制冷设施下，我可以使用什么样的系统来防止冻胀，它将是无故障、成本最低、安装合理简单的？”要回答这个问题，我们必须回到物理学的基本原理，这些原理涉及到地板为什么会真正隆起。引文:俄亥俄州辛辛那提ASHRAE学报第87卷第2部分研讨会

Since the turn of the Century, floors in refrigerated facilities kept at 0°C (32°F) or lower have buckled and heaved. The destruction of floors in such facilities has been widespread, and many systems have been used in an attempt to prevent such heavage in new facilities. A few methods have been used to reduce the heavage in existing facilities where floors have already buckled.The problem of heaved floors has not been universally solved since most methods have been used either indiscriminately or the applicator has not understood what principles are involved in the methods he is using. Once a facility has been built, and if the method of floor heavage prevention is not adequate and has been installed improperly, it is not only difficult, costly, but also time-consuming to rectify the mistakes after the floor has in fact heaved even though a system was installed to prevent such a heavage. The question seems to be always in front of us: "What system can I use in preventing frost heavage under the refrigerated facility being designed and constructed which will be trouble-free, least costly, and installed with reasonable simplicity?"To answer this question, one has to go back to the basic principles of physics involved with why a floor actually heaves.
