Does Cordwood Construction Require Specialized Tools?

Basic Tool Requirements

While cordwood construction does not need a wide array of specialized tools, some specific equipment is necessary to handle the logs and mixing mortar. Typically, a person building a cordwood structure will need a chainsaw or a log splitter to cut the logs into the required sections, a maul or a sledgehammer to split the logs, and a hand saw or a chainsaw to prepare the ends for notching. A trowel and mixing bucket are also essential for applying the mortar mix.

Log Preparation and Notching

To achieve a tight seal and ensure structural integrity, it’s crucial to notch the log ends properly. A notch depth of about 1/4 inch (6 mm) is usually sufficient, and the notch should be about 1 inch (25 mm) from the top of the log. A hand saw or a chainsaw can be used to make the notch, and a maul or a sledgehammer can be used to tap the log into place. A cordless drill with a mixing bit can also be useful for mixing the mortar. A well-notched log end will provide a strong foundation for the structure.

Mixing and Applying Mortar

A well-crafted mortar mix is essential for a successful cordwood structure. A typical mix ratio for a cordwood mortar is 1 part cement, 1 part lime, and 3 parts sand. The mixture should be consistent and free-flowing, but not too wet. A trowel can be used to apply the mortar mix to the notched log ends, and a level or a string can be used to ensure the structure remains level and plumb. A cordwood structure should be built in a way that allows for adequate insulation, typically using materials like straw bales or recycled denim.
