Kosteusjäämät

Kosteusjäämät, meaning residual moisture, refers to the presence of water or dampness that remains in building materials or structures after a construction or renovation project, or after a moisture event such as a leak or flood. This residual moisture can be problematic if not properly addressed, as it can lead to a range of issues.

Common sources of kosteusjäämät include inadequate drying times between construction phases, rain exposure during construction, leaks from plumbing or the building envelope, and insufficient ventilation. The materials most susceptible to retaining moisture include wood, concrete, plasterboard, and insulation.

The presence of excess moisture can foster the growth of mold and mildew, which can negatively impact indoor air quality and pose health risks. Furthermore, persistent dampness can lead to the degradation of building materials, causing structural damage, rot, and corrosion of metal components. It can also contribute to unpleasant odors.

Identifying and quantifying kosteusjäämät typically involves moisture meters that measure the electrical resistance or capacitance of materials. Infrared cameras can also detect temperature differences that indicate underlying moisture.

Effective management of kosteusjäämät requires proper drying techniques, often involving ventilation, dehumidifiers, or specialized drying equipment. Ensuring adequate ventilation during construction and in occupied spaces is crucial for preventing future moisture accumulation. Addressing the source of any leaks promptly is also essential.
