Which type of membrane is categorized as a cleavage membrane?

A cleavage membrane serves as a separation layer between a substrate and the tile or vinyl flooring applied on top. This type of membrane is designed to allow for movement between the two layers without compromising the integrity of the finished floor.

Reinforced asphalt paper is classified as a cleavage membrane because it provides a certain level of waterproofing while allowing for the structure beneath it to expand and contract. It typically consists of an asphalt-saturated paper that can effectively manage moisture and provide a barrier while maintaining a degree of flexibility, which is essential in tile installations where movement is expected.

The other types of membranes mentioned, such as chlorinated polyethylene sheeting, high solids cold liquid applied membrane, and polyvinyl chloride, serve different purposes. Chlorinated polyethylene sheeting is often used for roofing and waterproofing applications rather than as a cleavage membrane. High solids cold liquid applied membranes provide a seamless waterproofing solution but are not designed specifically for separation between layers. Polyvinyl chloride membranes are commonly used in roofing and other environmental applications but do not fit the definition of a cleavage membrane in the context of flooring installations.
