What is the line Frost?
freezing line is the depth into which ice or frost penetrates into the ground. Although the factor is often thought out in terms of general weather information, it is very important for building regulations. The freezing depth is determined by different factors, including the temperature, the time at which the air temperature remains under the freezing and moisture levels in the ground. Other factors, such as exposure, amount of vegetation and soil use, could also play small roles in determining the exact depth.
The easiest way to determine the depth of frost for the area is to consult a frost map. The map serves as a general link and finding a specific zone should provide an exact idea of what can be expected even in the worst winters. In most cases, local inspectors should also have information about Frost. This local source of information is often the most accurate because it is finely tuned to a specific area in a way that the National Map of CAN to be.
freezing line can vary very much from one place to another. For example, there is no front line for Floride in the United States, but in some northern parts of the lower 48 states there may be up to 60 inches (152.4 cm). In the minnesota, the maximum of 60 inches (152.4 cm) in northern countries has a maximum of 60 inches (152.4 cm), but in southern countries it reaches only 40 inches (101.6 cm). Some frost maps show the average freezing depth for the state, but these are very unreliable information and should not be the basis of any decision due to the scattering described.
Although the range of frost penetration is not relevant to most people, it is important because the posts and the foot foot must be installed in the country under the line Frost. If the underground parts of the support structure are above the frost boundary, the pressure exerted on the post or on the basis of it will be upside down. This could push out mail or position from the ground or even be responsible for major structural damage in buildings. Ensure that these structures are located nAt least a few inches below the line, this mitigates this concerns.
In fact, the location of the bases and contributions is such a main concern that it is often registered in the local Building Code. Those who do not follow the construction regulations on the Frost line may find that they must make extensive project modifications before it is approved for use. Even if it may be an inconvenience, it will save the consumer with the difficulty of repairing work that has been done incorrectly from the beginning.
