What is the freeze line depth commonly found in Texas?

The freeze line depth commonly found in Texas is typically 18 inches below grade. This depth is significant because it provides guidelines for various construction and installation practices, particularly for utilities and on-site sewage facilities. In areas prone to freezing temperatures, knowing the depth of the freeze line helps prevent damage to pipes and other installations due to frost heaving.

Factors such as location, soil type, and local climate can influence the freeze line depth. However, 18 inches serves as a general standard across many Texas regions, providing a balance between preventing freeze damage and practical installation conditions. Understanding this depth is essential for installers to ensure the proper operation of on-site sewage systems throughout the colder months.
