Understanding Fence Post Cracking: The Process of Checking

Introduction:

Explanation of “Checking”

     “Checking” is a natural result of lumber seasoning or drying our, particularly noticeable in      round or square wood timbers.

Insights from USDA Research:

     The USDA Forest Procuts Laboratory in Madison, Wisconsin has extensively studied this phenomenum.

     According to USDA Bulletin #1187, round items are more challenging to season due to the presence of heartwood and sapwood, leading to stresses and the development of V-shaped checks.

Understanding the Drying Process:

     When a full round or square timber dries, the exterior surface (sapwood) shrinks faster than the inner heartwood, resulting in checks.

     This checking is not technically a split or crack but rather a natural adjustment of the wood during the drying process.

Comparing Different Timber Forms: 

     Checking is less visible but still possible in boards and planks due to more even drying from being cut from larger trees and sawn on four sides.

Assurance of Strength:

     Laboratory and field tests indicate that the natural checking of full round materials does not impact their strength.

     Users of full round timbers or dimensional members can be confident that checking, though likely to occur, will not weaken the structural integrity of the fence posts.
