HOW LOGS BECOME WALLS
horizontal interface surfaces are perhaps the simplest. They usually use a butt-and-pass corner design, dry or well-seasoned wood that isn’t surfaces require precision milling machinery, which cut lengthwise into the horizontal surface to form a single or double tongue-and-groove configuration. The tongues are on the top where they won’t catch and retain water, and the grooves are milled into the bottom. When the logs are stacked, the tongues and grooves fit together to create a tight seal, and the inside and outside edges of the surfaces provide a wide base for structural stability.
