What Is the Difference Between Damp-Proofing and Waterproofing?<\/strong><\/h2>\n

The selection of hydro-insulation<\/strong> depends on the soil conditions<\/strong> and the groundwater level<\/strong> at the construction site. Damp-proofing and waterproofing<\/strong> serve different purposes, and conducting a soil survey<\/strong> should be the first step before starting construction. This will help determine the right type of hydro-insulation<\/strong> for the project.<\/p>\n

Damp-Proofing<\/strong> vs. Waterproofing<\/strong><\/h4>\n
    \n
  • Damp-proofing<\/strong> protects against non-pressurized water<\/strong>, such as rainwater and capillary moisture<\/strong> from the ground.<\/li>\n
  • Waterproofing<\/strong> shields foundations<\/strong> from pressurized water<\/strong> that exerts force on the underground parts of the building, providing a higher level of protection<\/strong>.<\/li>\n<\/ul>\n

    It is not always possible to predict future threats<\/strong> to a building\u2019s foundation. Even newly built houses in the surrounding area<\/strong> can alter the groundwater level<\/strong>, increasing the risk of water pressure on foundations<\/strong>. If pressurized water<\/strong> appears, damp-proofing alone will not be sufficient<\/strong>.<\/p>\n

    Damp-Proofing (Moisture Barrier)<\/strong><\/h3>\n
      \n
    • Applied to the subterranean and base levels<\/strong> of a building situated above the groundwater table<\/strong>.<\/li>\n
    • Used when there is no hydrostatic pressure<\/strong> from rainwater on foundations or foundation walls<\/strong>.<\/li>\n<\/ul>\n

      Waterproofing<\/strong><\/h3>\n
        \n
      • Applied to the subterranean and base levels<\/strong> of a building located above the groundwater table<\/strong>, but in impermeable soils<\/strong> where hydrostatic pressure from rainwater<\/strong> is present.<\/li>\n
      • Required when the building\u2019s foundation (or parts of it) are positioned below the groundwater table<\/strong>.<\/li>\n<\/ul>\n
