How to save the land and the house from flooding: install roof and surface drainage

How to save the land and the house from flooding

Removing water from the site is the main measuresaving the stability of house foundation. guttering system prevents the erosion of the land, preserves the integrity of road surfaces, increasing the service life of concrete and paving slabs. So zealous owners provide a full range of devices, allowing to withdraw from the territory of area rainfall, the effects of snowmelt and closely spaced groundwater. Consider what functions are performed by surface drainage and other species.

Tasks guttering

The organization of water withdrawal systems with multiple site systems must be used, because they complement each other, solving the flooding problem comprehensively.

  • Drainage from the roof of the building to protect itself from destruction and subsidence of the foundation.
  • Surface systems solve the problem of withdrawal of deposits from all over the site.
  • Deep drainage is struggling with a high level of soil moisture, in which blame closely spaced groundwater.

Roofing systems: the appearance and function

Since the house is built beforebeing improved land, its protection from precipitation engaged first. This function takes the drainage from the roof. It is a system of gutters under the roof, which falls in the water flowing down the roof covering. At the end of the chute begins pipe through which waste water showers are displayed in the receiver, which is part of the surface drainage. The more complex the design of the roof, the greater the number of gutters and pipes have to be mounted.

Prepared structure manufactured from plastic,copper, painted or galvanized metal and metal with polymeric coating. The cheapest is the drainage of galvanized steel, but if it is often brushed from ice and icicles, then quickly damaged galvanization. The copper version of the most durable, but also very expensive. His mount is only complete with the same type of roof. Most often used in new plastic gutters and downspouts. They are not afraid of corrosion, easier to install, easier to metal, and the life of the producers provide at least 10 years. In some types of coatings, such as shingles, metal, and does not apply, because it can damage the mineral grit, which is washed away from the surface of the coating at the time of precipitation.

The most common system is mounted on the outside, but ifThe building is situated in a cold climate zone where the effluent may freeze in the pipes or gutters, it is recommended to install an internal drainage. It consists of rainwater heads, risers, and external drain pipes release.

In domestic wastewater remains open only issue on which the water flows out of the house, and risers and pipes are located inside the building

Lead rainfall and melting snow from the area: the options of surface water discharge

After the erection of all the buildings it is timeto remove water from the surface. It is necessary that after the rain does not stagnate on the site pools, plants did not feel waterlogged, and during heavy rains the water flows are not tempted to the foundation and the tracks, causing subsidence. For this purpose, surface drainage is laid, which covers most "flooded" section of seats.

There are two types of surface systems, which are better to lay complex.

Linear drainage for areas with flat terrain

If the cottage is located on flat terrain, whereduring rain water does not flow in specific places, because there is no bias, the only way to eliminate waterlogging is a linear drainage. It is a system of trays, and covered with grates arranged in the whole area. Grilles are protected against ingress of large debris, but does not hinder the passage of precipitation into the design.

The trays are placed in a trench, dig now so thatThey were at a slight slant to the place of water intake. On the meter of the angle of inclination should be approximately 5 ?. To do this, dig a trench with a bias to either buy water drainage channels, which have provided the desired angle.

To see if you guessed a slope when diggingditches, to mount trays miss gutters on water ways, including full power garden hose. If the thread will run to the inlets freely, then the slope is sufficient. In the case of water delays in areas of slow flow should be increased slope angle. The number of drainage veins depends on the composition of the soil. The more clay in it, the more worth digging ditches.

To protect the main track in the areapaving rainwater trays on the sides of the cover. This road drainage to avoid waterlogging bedding sand and soil under the tile and concrete. Wet surface becomes unstable and can "float" under the wheels of heavy equipment. This means that the base coat and go cracks.

Point system: localized floods in specific locations plot

Point outfalls are considered the easiestone for removing the excess water from the area suffer from floods only during floods or heavy rains. The rest of the water itself out of the ground, thanks to the natural slope of the terrain.

This design represents the receiving waters,who digged in problem areas the site where, after the rainy long standing puddles. These include: the end of the pipe roof gutter, porch area and the main entrance. More specifically, to determine the point of arrangement of water intakes can be after the rain, seeing pegs most flooded areas.

Point drains

Point drains put in places of the most powerful streams of water

Ranked in the drain water can accumulate in a specially dug tanks, then to be used for horticultural purposes, or is displayed in the storm sewer system.

A variety of dot design isdrain drainage. It has a two-section shape and plays the role of a filter for entering into the precipitation. The first section is all rubbish, and from the second clean waste water goes into the sewer or directly into the soil through the drainage capacity. Periodically, the owners can clean the drain to waste does not interfere with the care of precipitation. This structure is provided and trap odors, so near the gutter will not smell the stale, swamp water.

Deep drainage for areas with high water table

The second problem, causing waterloggingland - located high groundwater. During the spring thaw perched water level rises so that the soil turns into a month in perennial marsh. Such a regime can withstand rare plants. Therefore, the owners, which is so "lucky" with the location of villas, there is nothing left, how to create a deep drainage.

  • The depth of laying of drainage ditches

The first step is determined at what depth willlaid drainage pipes. No account is taken of the soil and the degree of freezing of the soil in your area. Drainage must be created below the freezing point, so that any remaining water from freezing in pipes and tore them. If the main component is a clay soil, dig the ditch at 70 cm depth, on loam - 80 cm, on sandy lands - meter or deeper.

  • place the water inlet

It is sure to create a slope When trenching inside water inlet (7 cm per meter). Space for collecting waste is usually disposed on the border area. You can create a special pit to bury a large capacity. In this case, you are always in the summer will be on hand supernatant water for irrigation. Option easier - to bring an end to the pipe off-site in a road livnevki.

  • Selection of drainage pipes

To acquire a deep drainageperforated tubes made of plastic. To openings are not clogged with sand and other debris, pipe wrapped with geotextile, and as an additional filter to create a gravel ditches podsypku. Some manufacturers of pipe wrapped in the filtering fiber directly on the plants.

  • trenching

The most effective system is recognized ditches dug"Tree" scheme. It represents one central large ditch, which runs to the sides (the branches) side. Groundwater flocking through the branches to the central unit, and from there translate into receiving waters or out.

Important! Deep drainage paving after the completion of the main building, that it does not accidentally crushed by heavy machinery.

If the entire system is designed and gutteringinstalled correctly, the owners forget about the flooding of basements, ground subsidence under the foundation and vegetable crops will be less likely to get sick of fungal infections.
