It made waterproofing liquid chemical products that went into or on cement and plaster. The products goals were to provide damp-proofing and waterproofing finishing for concrete and Truscon steel to guard against disintegrating action of water and air. == Description of water resistant products == From Truscon laboratories viewpoint waterproofing was considered methods and means of protecting underground construction like foundations and footings. It also pertains to structures intended for retaining water like water tanks and containing water under hydrostatic conditions like in water pipes, tunnels, reservoirs, and cisterns. Damp-proofing was considered the methods of keeping dampness out of the main part of concrete buildings. It involves the methods of treating exposed walls above ground level to avoid the entrance of moisture into the building. These definitions then qualified their various products as servicing particular needs. From the initial idea of protecting against water damage developed the science of integral waterproofing—the introduction of some element into the wet cement during the process of making causing a high degree of impermeability and imperviousness. Water in masonry does harm structurally because of its solvent properties and because it expands when frozen breaking concrete. Water is observed into concrete walls like a sponge absorbs water through capillary action. A wet wall produces damp and clammy conditions that promote and spread disease. While structural damp-proofing and waterproofing to prevent decay was a motive of the Truscon laboratories chemicals, the side benefit was that it provided better hygienic conditions. Some of the products developed for damp-proofing was Por-Seal, Stone-Tex, Stone-Backing, and Plaster Bond. Water Proofing Paste, an ingredient used in the making of stucco cement and plaster, was developed for waterproofing. Another waterproofing product was named Water Proofed Cement Stucco. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Truscon Laboratories」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
