Metal roof waterproofing construction attention to detail

Want to live in a newly renovated house, live a long time, live comfortably, then waterproofing is a very critical factor. Many consumers in order to save money, and the waterproofing of the house of simple construction, so that the use of the house a little longer, there will be many problems. Therefore, the construction of waterproofing is very important, today we will talk about the metal roof waterproofing construction attention to detail.

Metal roof waterproofing construction attention to detail

Construction if you meet the roof without insulation, be sure to wait until the insulation layer is dry before the construction of waterproofing, otherwise it will cause waterproofing drums on the waterproofing layer, seriously affecting the waterproofing layer of the use of life. Due to the insulation layer above a layer of cement mortar leveling layer, so it is difficult to visually check the dryness of the insulation layer before construction. In this case, most of the construction workers tend to rely on experience and feeling to determine the degree of dryness of the insulation layer, such a practice is not desirable, the construction aspects of the construction can not play a better role. In fact, the insulation layer in the drying process by the temperature of the environment, humidity, water absorption of moisturizing materials and construction factors have a great impact, so solely on the basis of experience and construction time to judge the length of time is completely unsure.

At present, there are many varieties of new roof waterproofing materials on the market, and the formation of a high, medium and low different grades of classification, these waterproofing materials have different characteristics and their respective scope of application. In the selection of waterproofing materials, we should be based on the building's grade, nature, function and structure and other characteristics as well as the region's environmental conditions to choose the appropriate waterproofing materials, such as polymer waterproofing roll-roofing and modified asphalt waterproofing roll-roofing for roofing and underground waterproofing projects, aging-resistant performance can be used for exposed projects.

In the construction also pay attention to the setting of isolation layer, first of all between the rigid waterproof layer and the grass-roots level to set up isolation layer, in order to prevent or mitigate due to the structural layer deflection and serious deformation, foundation subsidence, and temperature deformation and other factors lead to the rigid waterproof layer cracking, resulting in leakage of metal roofing. Further is the rigid protective layer and waterproof layer between the isolation layer, to prevent cement mortar, fine stone concrete and other rigid protective layer due to temperature difference expansion and contraction deformation, the waterproof layer will be stretched and extruded and lead to its destruction. The last is the inverted roofing pebble protective layer and insulation layer between the set of isolation layer. In the inverted roof insulation layer, such as the use of paving pebbles as a protective layer, in the insulation layer should be paved with a layer of fiber fabrics, and then paved pebbles. Fiber fabrics should be selected puncture resistance, durability and corrosion resistance of good materials, paving should be full paving, shall not be exposed to the bottom. The daughter wall of the building is pulled apart due to the thermal expansion and contraction of the structural layer of the roof. Therefore, in the structural layer and the daughter wall to leave a gap, take detachment measures, you can avoid or reduce the occurrence of this phenomenon.

So pay attention to waterproofing project maintenance and management of waterproofing projects are often combined with structural engineering and other mutual, roof waterproofing and leakage repair project construction is completed, there must be a finished product protection measures to eliminate leakage due to the destruction of the next process. In use should also be frequently maintained, inspection, in order to extend the service life of the roof. Improve the warranty system of waterproofing project, waterproofing project completion, leakage within 5 years, the construction unit must be responsible for the return to repair, the cost of the responsible party. Metal roof waterproofing project requires multi-party efforts, strict control, so as to achieve the use of roof function and durability requirements.

Metal roofing is the top of the steel factory building structure, but also by the most direct part of natural disasters, so for the metal roofing rust and corrosion prevention, waterproofing and leakage repair works is very important, in the construction process, we can not be careless, a step wrong, it may be the waterproofing of the effect of the weakening of water leakage due to its leakage of water damage or rust through the roofing plate. On the metal roof waterproofing construction attention to the details of the content, I will introduce here.
