What Does Caulking Mean?
Caulking is a general term in any field of construction. Caulking is the application of caulk, a sealant used to fill gaps or seams in pipe joints to ensure watertight or gas-tight integrity of those joints. Water-tight seams and joints are essential in underground piping. This is a fundamental process in trenchless construction.
Trenchlesspedia Explains Caulking
The ends of pipe and conduit segments must meet the manufacturer's tolerances and quality requirements. However, the ends will never match perfectly. This means small gaps will exist between pipe segments regardless of type. Caulking fills any gaps and seams.
The materials used for caulking are often specific to the uses and materials from which pipe or conduit is made. It's used in addition to mechanical seals, such as ring seals, because the seals may have uneven surfaces.
