Technical Measures for Limitation of Frost Depth in Soil

Abstract:

Renovation processes of existing buildings, including historically protected ones, are most of the time focused on energy saving. Nonetheless these processes might affect the function of existing shallow foundations. This paper deals with the influence of soils moisture content onto the depth of freezing. The depth of freezing depends on the type of soil as well, not just the moisture content. The influence of water and soils composition are generally perceived to be substantial for depth of freezing. Sub-zero temperatures do significantly change the soils characteristics, which has an effect to the building structure. The purpose of the research done by the personnel of Brno University of Technology was to determine the effects of special measures against frost penetration of soil. These measures included the application of various materials and solutions over the terrain in winter to monitor frost depth of soil.
