Waterproofing is the combination of materials used to prevent water intrusion into the structural elements of a building or its finished spaces. Its main purpose is to resist hydrostatic pressure exerted by moisture in the liquid state. Waterproofing membranes consist of waterproof plastic, rubber, or coated-fabric materials. The materials are used in a system to prevent the ingress of water into foundations, roofs, walls, basements, buildings, and structures when properly installed. The term dampproofing is often confused with waterproofing, however, dampproofing is a system designed to resist the flow of moisture in a gaseous state i.e. water vapor.we are bitumen waterproofing membrane sheets supplier in azad kashmir .

Location of Waterproof Membrane

Depending on the structure and need, the waterproofing membrane can either be applied to the interior (negative), such as the case with repairs, the exterior (positive), or in places inaccessible by people (blindside).

Positive side of mbranes are applied to the exterior face of a structure. It can be applied above, below, or at grade to surfaces that will get wet due to exposure to weather conditions and the surrounding soil. Positive waterproofing is a critical step in construction because it prevents moisture infiltration and protects structural components, including the concrete and steel. It can also protect the surface from freeze-thaw cycles and corrosive chemicals. When used for below grade surfaces (such as sealing a foundation) it is available as a fluid applied membrane, sheet-membrane, or as hydros clay and vapor barriers. The disadvantage of positive side waterproofing is that it is inaccessible after construction except with costly removal of the topping landscape. Positive side waterproofing should be used alone when the surface will be exposed to corrosive soil, freeze-thaw cycles, and if there will be limitation to the interior humidity.we are bitumen waterproofing membrane sheets supplier in azad kashmir

is applied to the interior face of a structure. It keeps water from entering an occupied space and is applied to what is known as the dry face. Negative side waterproofing is primarily used for water holding purposes (prevent water from entering space), but it does not prevent the water from entering the substrate (wall). The materials used for negative waterproofing must be able to withstand hydrostatic pressure. The most commonly used materials are epoxy injections and cementitious coatings. The advantage of negative side waterproofing is that it is accessible after installation for repairs or updates. Negative side waterproofing allows moisture into the substrate which can be seen as an advantage and disadvantage. Moisture promotes active curing of the concrete substrate, but it contributes to the corrosion of the concrete and steel reinforcements from the groundwater and chemicals. This type of membrane does not protect against the effects of the freeze-thaw cycle and can only be used on cemenitious systems unicorn chemical is bitumen waterproofing membrane sheets supplier in azad kashmir
