what is corking in building

Caulking is the process of sealing gaps or seams in various structures to ensure watertight or gas-tight integrity. It is typically used in construction and repair projects, such as sealing windows, doors, and other building materials. Caulking is done using a waterproof material called caulk, which is made from flexible polymers. It is the least expensive of the four types of sealants and is readily available in rope and tube form. However, caulking has low durability, lasting only 1-4 years, and poor adhesion to porous surfaces like masonry. It should be painted and can be toxic, so it is important to check the label. Regular caulking and waterproofing is important for building envelope repairs to prevent water damage and air leaks.
