How to Protect Cordwood Masonry from Water Damage?

Choosing the Right Waterproof Sealant

Select a waterproof sealant specifically designed for exterior use on masonry, such as a silicone-based or silane-based sealant. These sealants can withstand harsh weather conditions and provide long-lasting protection. Apply the sealant to the exterior surface of the cordwood masonry, ensuring a 1/4 inch bead is applied around the corners, joints, and edges.

Proper Drainage System Installation

A well-drained drainage system is essential to prevent water accumulation around the cordwood masonry. This can be achieved by installing a French drain or a perforated pipe around the perimeter of the structure. The pipe should be sloped to direct water away from the foundation and the cordwood masonry. For optimal results, install the drainage system at least 6 inches below the grade level.

Insulation and Weatherproofing

To prevent water damage, it’s essential to maintain a consistent temperature and humidity level within the cordwood masonry structure. This can be achieved by adding insulation to the log ends and the walls. Use a high-quality insulation material with an R-value of at least R-10. Additionally, ensure that the cordwood masonry is properly weatherproofed by applying a breathable, water-resistant coating to the interior surface. This will help to prevent moisture from entering the structure through the log ends or gaps in the mortar.
