What is the depth of lead poured over oakum in a caulk joint?

In a caulk joint, the depth of lead poured over oakum is typically recognized as being a standard measurement of 25 mm. This depth ensures that there is sufficient material to create a watertight seal while minimizing the risk of damage caused by thermal expansion or contraction. The use of oakum in combination with lead helps to fill the gaps, providing support and stability in the joint.

Having the proper depth is critical for effective sealing and maintaining the structural integrity of the joint, which is essential in plumbing and HVAC systems where leaks could lead to significant issues. A depth of 25 mm is standard across the industry and contributes to proper installation practices in various applications.
