An integral part of the system to protect any home from waterlogging is the ebb. Experts recommend to mount them to protect the walls and foundation of the house from dampness and mold. If you do not provide adequate protection, the walls can lose their insulating properties, while the building will gradually begin to lose its aesthetic appearance and collapse. From the point of view of places of protection, distinguished basement, window and roofing ebb.
In the article we will tell you how to make ebbs on the roof with your own hands from various materials (galvanized, plastic pipes, stainless steel), consider the process of mounting ebb, and give photos and video instructions.
What should be the drains
Materials for low tides
Due to constant the impact of adverse environmental factors (precipitation, temperature changes, sun, wind), the correct choice of material ebb is extremely important.
Modern ebb is made from different materials.
Galvanized steel . For the manufacture of castings used steel sheets, with a thickness of 1 mm. For additional protection against corrosion and aesthetics of the structure, polyester, pural or plastisol coating is used.
Aluminum . The thickness of the original sheets is 0.8-1 mm. To protect against corrosion, a special multi-colored varnish is used, which also allows to improve the appearance of the ebb.
Copper . It can be used both without treatment, and with oxidation or brass. It is considered the most beautiful, high-quality and durable material for the manufacture of castings. It has a significant disadvantage - a high price.
Polymers . Due to low cost, increased durability, noiselessness, resistance to ultraviolet radiation and durability, polyester and plastisol are widely used in the manufacture of ebb. Due to the low weight and ease of installation, it is quite possible to mount the ebb for the roof.
Composition of the drainage system
The drain system consists of several elements .
Gutters. Designed to collect water flowing from the roof slopes.
Funnels . Used to receive water from the gutters and then direct it to the pipes.
Pipes . Used to transport water to special water intakes.
Different turns . They are used to bring the pipes closer to the walls of the building, provide an opportunity to avoid obstacles and prevent water splashes from reaching the basement of the building by installing them at the bottom of the pipes.
Stub . Designed to limit the flow of water. They are mounted on the ends of the gutters.
Fastening elements . Special brackets are used for mounting gutters. To fasten the pipe clamps are required sizes.
Calculation of material for castings
The number of grooves corresponds to the length roof slopes.
The number of drain funnels is determined based on the length of the slopes. Usually one funnel is installed on 10 running meters of a slope. With a greater roof length, it is necessary to provide several discharge points.
The number of pipes (total length) is calculated based on the number of discharge points, the distance from the installation points of the craters to the ground, taking into account the features of the facade.
The number of turns is calculated on the basis of the features of the facade of the building and the discharge points.
The number of brackets is determined based on the calculation of: at least one bracket per linear meter of the mounted trough.
The number of clamps used for pipe fastening depends on the number and length of pipes (at least 2 for each pipe). In addition, each pipe section must be secured at least in one place with a special clamp.
Drainage installation scheme
Modern external drains , in fact, are a constructor that should be properly assembled. The density of the connections is provided by the manufacturer. The presence of an assembly drawing describing the principle of assembling a structure will greatly facilitate the installation process.
When installing the gutters of the drainage system, it is necessary to follow the basic principle - the principle of slopes and tightness of connections. To ensure rapid flow is required to provide a slope of 2-3 °. Visually, this bias is not noticeable and does not spoil the appearance. If desired, the slope can be increased to 5 °, but in this case it will become noticeable and the view of the building may be damaged.
Assembly of the individual parts of the gutters should be carried out in the direction of water movement.For additional sealing compounds can be used sealant.
Assembling the pipes is sufficient to ensure the tightness of the connections.
When installing a drainpipe system, follow the manufacturer's recommendations for fastening methods. Also, be careful, because the work is carried out at altitude.
Proper use of the ebb will protect your house from the negative effects of precipitation, decorate it, preserve the appearance of the building for a long time and significantly prolong its service life.
