Concrete floors lying on ground that contains pyrite (iron(II) disulfide) are also at risk. As a preventive measure sewage may be pretreated to increase pH or oxidize or precipitate the sulfides in order to minimize the activity of sulfide-reducing bacteria. [citation needed]
Gypcrust forms in a manner similar to that of caliche, which is composed of calcium carbonate.The development of gypcrust has three main stages. The first stage is primary crystallization of the surface brines or groundwater; the second stage is transportation and redeposition by wind or water; and the third stage is post-depositional alteration above or below the capillary fringe.
Cracks in the walls and ceiling and gaps in the flooring can indicate significant problems. Also, check out common areas like hallways and stairwells for indications of structural issues or ...
A floor is the bottom surface of a room or vehicle. Floors vary from simple dirt in a cave to many layered surfaces made with modern technology.

Epoxy moisture control systems are chemical barriers that are used to prevent moisture damage to flooring. Excessive moisture vapor emissions in concrete slabs can mean significant, expensive damage to a flooring installation. Hundreds of millions of dollars are spent annually just in the United States to correct moisture-related problems in ...
“Recovery typically occurs within 1-3 days, though symptoms can persist longer in severe cases, in the elderly, or in persons with other health problems,” says Dr. Chung.
Gypsum concrete is a building material used as a floor underlay [44] used in wood-frame and concrete construction for fire ratings, [44] sound reduction, [44] radiant heating, [45] and floor leveling. It is a mixture of gypsum, Portland cement, and sand. [44] One of its advantages is the lightweight nature.
