How do you seal between the logs ?

We cut a groove down the bottom of every exterior wall log, this groove has a special "shelf cut" on each side for placing and holding an expanding foam gasket. This gasket is applied to both sides of the groove. On installation, this gasket is compressed to approximately 3/8" to 1/2", if there is any movement of the joint between the logs, this gasket can expand up to 1-1/8". Notches and the groove are also insulated with fiberglass insulation or optional Natural Wool.
