List of featured suppliers of CAVITY TRAYS Building Extension on Building Products Index
Cavity trays are a type of waterproofing mechanism that is used to prevent water from penetrating the joint between two building elements. They are typically installed in building extensions to ensure that water does not seep into the walls or floors, causing damage or deterioration over time. These trays are made from various materials such as lead, plastic, or reinforced concrete and are carefully placed to allow water to run off without entering the structure. Cavity trays are an essential component in any building project, especially when constructing extensions that are subject to potential water damage.
