The most common question I get has to do with the large horizontal splits in the logs which are commonly mistaken for cracked or damaged areas of the logs.
This is part of the natural drying process of logs! The checking as it is called does not impact the structural integrity of the log, but depending on the location, size and or depth of the checking water seepage can become an issue. With severe checking we do recommend sealing with an approved flexible sealant.
This is a good example of chinking and end logs that are checking. At this stage not much is needed. Just monitor over the next season to see if the checking increases. With it being located on the bottom portion of the logs, it should not be an issue.
This is an example of chinking with round end logs. This is a flexible chinking compound.
The old mortar based chinking that we still see absorbs water and does not allow for proper drying of the spaces. This leads to and increase in water seepage and damage of the area.
The brands of Chinking we like are called Perma_Chink and Big Stretch and Log Jam by Sashco.
