Have been looking for information on frostline. Found a post here and was hoping you could help. Trying to find out what our local frostline is. I am located in Lubbock, Texas. Where can you find this information and why is the frostline so important. Locally they are trying to reset our frostline to a deeper depth. We have a committee researching this and have had a difficult time finding the needed information. This is very important because it will not only affect contractors but the extra cost will of course be passed on to the consumer. Would appreciate any direction you could give. Thank you in advance for any help you could give in this area.
