Hello . I have a question for you . I have a house of logs 8 m 10 m and the fact, what line lengthwise of the logs did not axe properly, and a chainsaw and a full-length logs there is an empty space between the crowns . The house is 3 year , fully sat down and prokanaet does not work. I was advised to drill at a distance of half a meter in length logs holes and into the voids blow out foam . Is it possible to do so and will eventually rot or dry Logs ?
