Prefabricated Cement House Roof Treatment
The treatment of prefabricated cement house roofs mainly includes four aspects: reinforcement, waterproofing, plastering the base, and thermal insulation. The specific treatment methods are as follows:
Reinforcement Treatment: When the prefabricated panels show signs of separation or damage, they can be refilled with cement mortar, and the thickness of the steel bars can be increased to enhance structural strength. If the roof shifts, iron pipes can be used for support, or brick piers can be added at key positions to provide additional support. These measures can effectively improve the stability and load-bearing capacity of the roof, preventing further damage caused by structural issues.
Waterproofing Treatment: Due to their structural characteristics, prefabricated panel roofs commonly suffer from rain leakage problems and require regular waterproofing treatment. Waterproofing is a crucial aspect of roof maintenance, directly affecting the service life of the building. As long as the wall structure is stable, a prefabricated building that has undergone proper waterproofing treatment can have a service life of over 50 years. The selection of waterproofing materials should consider durability and adaptability to ensure good performance under different climatic conditions.
Plastering the Base Treatment: For prefabricated concrete floor slabs, fine aggregate concrete should be used to fill the panel joints to prevent cracking caused by temperature changes or loads. Before filling, the sand and mortar adhering to the panel joints should be thoroughly removed with a wire brush to ensure full adhesion between the filling material and the base. This step is crucial for improving the overall integrity and durability of the roof and can effectively reduce later maintenance costs.
Thermal Insulation Treatment: To enhance the thermal insulation performance of the roof, materials such as polystyrene boards, rock wool boards, or polyurethane foam can be selected. These materials should be evenly laid on the treated cement roof, with a thickness controlled between 20 to 30 centimeters, ensuring seamless coverage. After laying the thermal insulation layer, a waterproof layer, such as waterproofing membranes or coatings, should be added to prevent moisture penetration from affecting the insulation effect. Finally, subsequent treatments such as leveling and decoration should be carried out according to design requirements to make the roof both functional and aesthetically pleasing.
