Various sized cuts of 1 ⁄ 2 in (13 mm) drywall with tools for maintenance and installation . Drywall (also called plasterboard, dry lining, [1] wallboard, sheet rock, gib board, gypsum board, buster board, turtles board, slap board, custard board, gypsum panel and gyprock) is a panel made of calcium sulfate dihydrate (), with or without additives, typically extruded between thick sheets of ...
Gypsum concrete is lightweight and fire-resistant. A 1.5-inch slab of gypsum concrete weighs 13 pounds per square foot versus 18 pounds per square foot for regular concrete. [10] Even though gypsum concrete weighs less, it still has the same compressive strength as regular concrete, based on its application as underlayment or top coat flooring ...
In 1940, the U.S. Justice Department filed suit against USG and six other wallboard manufacturers, charging them with price fixing under §§ 1 and 2 of the Sherman Act. The claim stemmed from US Gypsum's 1929 cross-licensing agreements for its patented wallboard, which set prices at which the wallboard must be sold.

The expected minimum sensitivity of the water-based bare geomembrane liner integrity methods is a one millimeter diameter circular leak. For the arc testing method, water is not required. A high voltage (Approximately 5000V-35000V) with a very low current is introduced above the geomembrane and grounded to the conductive layer below it.
