Effect Of Vapor Barrier And Construction Method

                The purpose of a damp-proof layer in the wall is to prevent soil moisture from rising along the base wall and the surface water on the foot of the wall. Its role is to improve the durability of buildings and maintain indoor dry hygiene. When the indoor floor is paved, the exterior wall of the damp-proof layer in the indoor floor below 60mm; When the walls of the building are unequal, on each side of the surface of the 60mm, Moistureproof layer should be set separately, and in the two damp-proof layer of the wall between the vertical damp-proof layer; When the indoor floor is used as an aerial floor, the outer wall moisture-proof layer should be located above the outdoor floor, under the wooden joists. The wall moistureproof layer generally has the roll material moistureproof layer, the waterproof mortar moistureproof layer, the fine stone concrete moistureproof layer and the reinforced concrete moistureproof layer and so on.Vapor Barrier

                The role of moisture-proof layer in the wall is to prevent soil moisture from rising along the base wall and the surface water of the foot part of the wall; its role is to improve the durability of the building, to maintain indoor dry health, moisture-proof layer of indoor floor below 60mm; When the interior wall inside the floor is unequal, on each side of the surface of the 60mm, moisture-proof layer set separately.Vapor Barrier

                A damp-proof layer shall be provided on the outer surface of the equipment or piping cold insulation layer and the insulating layer laid in the pipe of the trench. The damp-proof layer construction often uses the smearing method and the banding method. (1) Smearing method. A damp-proof layer construction method for attaching a layer or multilayer material on the surface of an insulating layer and layering it on top of the coating material. (2) Banding method. Apply damp-proof film and sheet material to the surface of insulating layer, then tighten it with strapping material, and the construction method of damp-proof layer which is sealed by binder and sealant.Vapor Barrier
