Rating of the best drainage channels and storm drains for 2022

The creation of a well-equipped stormwater / drainage system is the key to effective and modern removal of excess moisture in the territory of a country house. Exceeding the permissible level of water concentration in the soil will easily lead to a gradual deformation of the foundation, an increase in the level of humidity in the basement and basement spaces. Among other things, excess water will contribute to the rapid development of mold and fungal colonies.

Purpose of drainage systems

It is a complex of elements, which includes special trays or pipes designed to drain excess water from the backyard. The water collected in a special reservoir, with the help of a special drain system, will later be transported to the nearest reservoir or ravine. The main purpose of a storm drain is to protect the foundation of buildings from the harmful effects of groundwater and to ensure normal soil moisture indicators, which clearly contributes to the growth of crop yields.

Increased soil moisture can be associated with shallow water in the ground, heavy precipitation or accelerated snow melting and can lead to serious troubles:

• The presence of excess water in the ground condones its uneven distribution under or near the foundation.This may not be a problem if the house is built on a pile-screw or pile foundation, however, if the building is erected on a shallow foundation, then the likelihood of frost heaving during the cold season increases greatly.
• The frozen soil under the foundation acts on its sole and pushes it up, while the supporting structures do not experience such movement. This can lead to both the destruction of the foundation itself and the walls of the building. A similar situation may arise with paths paved with paving slabs or other material.
• High humidity contributes to the spread of mold and other fungi, worsens the overall microclimate in the room and provokes colds and respiratory diseases. Cases have been noted where the spread of mold led to the fact that the building had to be demolished.
• Excess moisture leads to rotting of the root system of domestic plants, which leads to a decrease in yield and their death.
• Also, if an outbuilding or a garage is located on damp soil, then premature corrosion of the tool, car and other metal objects of structural elements is inevitable.

The need for drainage

All of the above problems associated with high soil moisture can be eliminated or prevented with the help of properly arranged drainage, which promptly removes excess moisture outside the site or into a special container. There are a number of signs that clearly indicate the need for a drainage device:

• After rain, puddles and mud remain on the site for a long time;
• For no apparent reason, garden trees and houseplants die;
• Intensive mold formation in basements;
• The soil remains moist even during a brief drought;
• A large number of weeds that love moisture, such as nettles or cattails;
• the location of the site in a wetland or near a reservoir.

IMPORTANT! There are signs by which it can be unambiguously determined that groundwater flows no more than 1.5 m from the soil surface. With such a depth of the aquifer, a mandatory drainage device is required.

Types of modern drainage systems

Existing modifications can be divided into two categories:

1. Located on the surface (open);
2. Buried in the ground (closed).

closed point drainage

This variety involves the use of special pallets stacked in trenches. From above, the moat is covered with decorative gratings. This design provides free flow of water into the drainage channels, in addition, it excludes clogging of the channel with leaves, soil and other objects. Due to the affordable cost, high performance properties and a long period of operation, concrete trays and plastic trays are most widely used.

deep systems

Deep drainage is divided into two categories:

1. Local;
2. General.

In the presence of general drainage, moisture is removed from the entire territory of the site. The local drainage system is designed to drain water from a specific building or object located on the site. Such objects include: residential and outbuildings, garden paths, beds, etc. Depending on the design features, local drainage systems can be:

• wall;
• ring type;
• Plast type.

wall

It is advisable to use this type of drainage for the removal of melt and groundwater from basements and semi-basements built on clay and loamy soils. In addition, it performs preventive functions. Usually completed with pipes with filtering capabilities. To ensure efficient operation, the pipes must be located above the level of the foundation. The distance from the basement is determined by the design features of the building. If the foundation of the house is too deep, then it is quite acceptable to install such a drainage system on the surface. However, one should take into account the possibility of soil subsidence under the weight of structural elements.

ring drainage

This type of drainage allows for effective removal of excess water from foundation structures and from basements. Such drainage is used if the system of general deep drainage does not ensure the removal of excess moisture in full. Most often, this situation occurs on sandy soils. In addition, ring drainage allows for efficient removal of pressure groundwater. The ring drainage system is located below the floor level around the entire perimeter of the building. This arrangement provides effective protection against moisture in residential and commercial buildings. The functionality of the system is directly related to the area of ​​the site and the depth of groundwater. Ring drainage can be installed after completion of general construction work.

Reservoir drainage system

Used to drain groundwater. Laying is carried out in parallel with the construction of the building. Typically, such a system provides for communication with a tubular drain.It is advisable to install it above the ground level (containing groundwater) at the base of the building. Reservoir drainage has an underground drain, through which the collection and removal of groundwater is carried out.

Reservoir drainage is advisable in the following cases:

• The tubular system is not able to reliably protect the building from groundwater seepage;
• The soil of the site consists of various heterogeneous rocks;
• There are flooded closed zones on the territory of the site.

IMPORTANT! The main advantage of the reservoir drainage system is that it effectively removes not only groundwater, but also capillary moisture. Installation of reservoir drainage begins with sand filling under the building. Further, channels from crushed stone or gravel are formed in this sand. The depth of such channels should be at least 0.2 m. The location of the channels depends on the topography of the site and its hydrogeological features.

Surface drainage

The device for storm sewers to drain water is quite simple. The drainage tray is a gutter, which can be U-shaped or U-shaped, depending on the material. On top of such a drainage drain there is a grate into which rainwater is drained and subsequently redirected to the sewer.

Depending on the permissible load, such drain channels are divided into groups:

• A15 have a low degree of load, so they can only be mounted in relatively dry places: on sports grounds, along the paths of country houses, in areas where park and bicycle paths are located;
• B125 are more stable, so they can be mounted along the roads for cars;
• C250 are suitable for installation in car washes and car services;
• D400 are suitable for installation along roads intended for all types of transport, as well as in industrial areas;
• E600 is laid next to industrial plants and warehouses;
• F900 are suitable for installation near military bases, airports and airfields.

Drains are divided into groups not only on the basis of the load on them, but also on the basis of the materials from which they are made. The most common groups of raw materials used for the manufacture of gutters should be considered in more detail.

Plastic

For the manufacture of plastic stormwater use polypropylene and HDPE - low pressure polyethylene. All plastic models, due to the fact that they cannot be called durable, can only be classified as categories A-C. Plastic models are lightweight, and their installation by hand will not cause any particular difficulties. If the task is to equip the territory of a country house with gutters for water drainage, then it is recommended to choose plastic models. To increase the strength of such drainage systems, they are equipped with stiffeners. Reinforced plastic options are recommended to be installed near garages, since it is just required to use catchment drains of categories B-C there. Without a grate, the weight of one plastic gutter does not exceed one and a half kilograms with a standard length of 1 m. The width can vary between 7-30 cm. A grate is additionally purchased. It is recommended to choose a relatively light option, for example, made of galvanized steel. And stainless steel options are also suitable. Depending on where the drain is planned to be located, the strength of the grate should also vary. For example, near the garage, the grate should be large enough to support the weight of the car if you accidentally run over it.Polymer sand options are used at facilities under construction, as well as in underground parking lots. There are classes A and B.

metal

Metal rain gutters are a relic, as it seems to many. Most remember the days when such drains were everywhere on the streets. However, the metal does not lose its relevance to this day. It is difficult to find a material stronger and more convenient to use. The only unpleasant moment is that most metal products sooner or later corrode.

The most reliable are cast-iron gutters. In terms of strength, they can only be compared with concrete products, while they are able to withstand a lot of weight. Cast iron storm drains can be found near military bases and other military facilities, where there is a large flow of descending waters. Unfortunately, cast iron products have an impressive weight, which makes them not the most convenient for installation. However, this is where their shortcomings end.

Steel gutters can be of two types: galvanized and stainless steel. In both cases, the options are designed for a much lower load than cast iron, but this does not mean that there are no places for them to use. With the right shapes and placement, they will last no less. So, steel metal structures can be placed along the roads for cars, and they will also fit perfectly into park areas.

Reinforced concrete

These catchment drains combine all the advantages of concrete and metal structures. They are just as strong, have a huge range of categories for resistance to stress. Working with reinforced concrete is easier than just iron, so there is a fairly large selection of gutter shapes. There are not only traditional rectangular options, but also round ones.Reinforced concrete trays are used not only for industrial, but also for domestic construction. They are easy to install, despite their relatively high weight (which, however, is much less than that of cast iron or plain concrete). Both conventional drainage trays and slotted trays for heating mains are produced.

Remarkably, reinforced concrete trays should be used when the water has an aggressive composition. For example, the acid-base balance of pH is disturbed in it. Depending on the composition of the water, a similar design is also chosen, since some brands of concrete simply dissolve under the influence of alkali. Reinforced concrete drains are cheaper than metal counterparts, if we compare samples of the same category in terms of load resistance. When transporting, it is necessary to adhere to some rules, among which - try to avoid shock loads, otherwise the gutter may crack.

Composite

Composite trays are the modern version of concrete trays. Gutters of this type serve several times longer than concrete counterparts, but at the same time they are not inferior to them in terms of performance. Composite variations have some advantages:

• Less weight compared to concrete gutters;
• Ease of installation;
• Ease of transportation;
• Increased water permeability due to smooth surface.

Parameters affecting the selection of drainage pipes

The efficiency and durability of the drainage system is ensured by the right choice of drainage pipes. What does it depend on:

• From the area of ​​the site;
• Heights of groundwater occurrence;
• Average annual rainfall for the region;
• Type of soil on the site;
• relief;
• Laying depths.

In lowland areas, experts recommend using products with a diameter of 63 and 110 mm. They are able to drain the site along the sewerage within a radius of 4-5 m.Flexible single-layer products are laid to a depth of 0.7-1 m.

For example, wall drainage to protect the foundation is carried out with double-walled pipes with a stiffness class of SN 6. They can be placed at a depth of up to 2.5 m. The diameter depends on the volume of water that will pass through the drainage.

The choice of pipes depending on the type of soil:

• Crushed stone - perforated pipe, filter material is not required;
• Sand - pipes with geotextile + crushed stone sprinkling;
• Loam - pipes with a filter wrap + crushed stone sprinkling with a layer of up to 20 cm;
• Clay - pipes wrapped with geotextile or coconut fiber;

IMPORTANT! Pipe laying can be done without crushed stone. Expanded polystyrene in the form of small balls is used as a filter backfill layer.

Features of maintenance and operation of drainage systems

In order for the stormwater system to work properly for decades, while maintaining its throughput, after construction, it is necessary to follow the rules of operation and periodically carry out maintenance. For these purposes, the following points should be followed:

• Rain inlets, trays and other external elements of the storm sewer at home should be covered with grates to prevent large debris from entering;
• After spring floods and downpours, receivers and rotary wells are inspected and cleaned if necessary;
• Every two years, a major cleaning of all elements from debris and sediment is carried out, including rinsing from a hose;
• Every ten to fifteen years, if the need does not arise earlier, a major maintenance is carried out, flushing the system of deposits and deposits with pressurized water in both directions. Rigid blockages are removed mechanically if the hydrodynamic method does not work.

Timely maintenance of individual parts and periodic maintenance of the entire system is the key to trouble-free operation, and repairs, if necessary, without the need for dismantling.
