What is needed drainage around the house ?

Think about drainage around the house must be still in the construction phase, if you do not want to one day your home was flooded in the foundation cracks, or started to rot wall.

All of this - a consequence of infiltration of ground water into the base of the house.

not excessive and will blind area - it also protects the house from moisture.

Everyone knows about the need waterproofing, but few people think, that the drainage system - no less than the desired item.

Groundwater has in any soil, and, although rare, they can rise sufficiently to flood the basement.

But most likely will begin to penetrate the base, causing the development of mold and mildew, dampness and deformation of house foundation.

unlikely that you will want to constantly deal with the repair of your home, especially considering that the blind area, as well as the drainage is not too complicated and expensive undertaking as it might seem at first glance.

In this article you will learn about different types of drainage systems, as well as on how to make the drainage around the house.

presented video and diagram will help you get the job done correctly, so do not worry about possible problems with water in the future.

device types and drainage systems

blind area - the simplest form of protection against water.It does not replace the drainage, but will enhance its properties.To learn how to install it correctly, you will learn in the next section.

Types drainage differ in structure and way of functioning.

On the first ground drainage system is divided into perfect and imperfect.

first be established in accordance with the level of water flow, so that moisture gets there through the holes in the sides or top.Closed hand poured and tamped sand and crushed stone pillow.

second type of system is installed necessarily above the water level so that water penetrates it in three places: at the top, bottom and through the side holes.

Such a system should also be strengthened, sand and crushed stone pillow.

also shared surface and underground drainage: the first will protect the house from precipitation, the second - from penetrating into the basement and foundation of groundwater.

Construction of the drainage system is separated into a reservoir, ring and wall.

Formation drainage type less reliable, so often it is used as an auxiliary element to the structure of another type, or if the water table is not deep.

This drain is only suitable for clay soil and should be positioned close to the building foundation.

The reservoir drainage

Ring drainage - a reliable way to protect against the ingress of water into the ground floor and basement.

drainage This type is most suitable for the soil with a high sand content, ashe does not hold water, and quickly passes it through.

If you know that your area has a risk of flooding during heavy rains, it is best to choose this type of arrangement design.

annular drainage scheme has the form of a vicious circle, which eliminates the penetration of water into their fenced territory.

Install a drain to a depth below the level of the cap and at a distance of 2-3 meters from the construction of housing in order not to destroy the nearby soil.

Ring drainage

trim drainage type - the most common among private house owners.It is also the most reliable, becausenot only protects the building, but the lower floors (ground floor and basement) from flooding.

This type of drainage may be superficial or deep - and he and the other to effectively protect your home from moisture.

best thing to do trim drainage on soil with a high content of clay or a heterogeneous composition.If you are sure that the water table is close to the surface, then select the type of drainage is the best solution.

Construction construction going on right next to the walls -. At a distance of about 50 cm, it is set below the level of the basement.

Perimeter drainage

drainage Whatever you choose, work scheme will be approximately one.

Construction of drainage system

drainage system design is connected to pipes installed under the building foundation level.

Any drainage system is constructed at an angle to allow the moisture to drain.

To select a system, and method of installation, it is necessary, first of all, find out what depth of groundwater - this is done by evaluating the soil: dig it 2-3 meters to see overall.

Drainage around the house

Any drainage system should have a well, which will collect water.Install it is usually in the corner of the building, and the drainage system is carried out off-site, where work is underway.

If you know that your local soil is very wet or the water table is high, in addition to drainage, you can also consider additional waterproofing.

In more arid regions, and a drainage system would be sufficient.

Stages of work on the installation of the drainage system

Well, if in addition to the drainage will be done blind area and - if moisture protection will be almost 100%.

blind area - a band that runs around the perimeter of the house.It can be made of concrete, bricks and other similar material.

First, a blind area, and a drain, serves as drainage, but also often a decorative portion and a supplement, becauseon the surface it looks very interesting.

Set it as follows: in a trench stacked membrane that is filled with sand and gravel.

best if blind area is made of cold-resistant material - will last longer.

But still choose what material to do it, it should be based on the weather conditions in your area.

If the weather is often cold and rainy, it is best to choose the material of concrete.

Concrete blind area is as follows: first poured sand bag, which is filled with gravel and tamped, and the top is poured concrete solution and impose concrete slabs.Stitches in the joints need to pour asphalt.

If your site is set blind area, the drainage is done around it, its purpose - to remove excess moisture from the soil and protect the house as much as possible from water penetration.

Construction of drainage system begins with preparatory work: studying the soil and reveal the depth at which the groundwater occur, as well as work with the foundation.

drainage system

As mentioned above, the easiest way to learn the state of the soil - dig it 2-3 meters down: as a rule, the depth of the top layer of groundwater - no deeper than 2 meters down in the ground.

After that, you need to prepare the foundation.

It is treated with primer content of bitumen and kerosene, as well as make the waterproofing using asphalt mastic.Solution set top reinforcement mesh, which mesh size should be about 2x2 mm.

After drying - about a day - a grid covered with another layer of coating so that it could not be seen.

To make trim underground drainage pipe to choose.It is best suited for this plastic.In addition, the connection will be needed for them - couplings, elbows, tees.

first step is to make the site layout and select, which will host pipe and located well.

Any drainage needs in the well, where the water will be displayed.You can buy ready-made or make it out of concrete, but it will take more time.

If you chose a homemade version, then you need to make pits in your selected locations for the wells.The easiest way to make a square-shaped wells.

Watch the video installation at the well site.


Once the design is ready, you can do the trumpets.They are placed in a pre-dug trenches at an angle of about 2 cm

bottom of the trench should be pre-fill with gravel or sand, and on top close geotextile, which again is filled with gravel -. And it will be laid pipe.

the well pipe to be connected by joints and tees.After laying the need to re-check the correct slope and if done correctly, process pipes with cement mortar for fixing them in the trench.

pipes backfilled with gravel about 10 mm.Also, you need to wrap the pipe geotextile fabric, which should be placed overlapping.Secure it from the nylon thread or a special adhesive tape.

This is a diagram showing how to do the drainage around the house on their own.Watch the video with the stages of the work, the whole process has become clearer to you.


Surface drainage - a measure not less than necessary.He needs to collect rain water: rain and snow, which are sent to the sewer or sump, and thus does not accumulate on the territory of the plot and do not get into the house.

most efficient surface drainage - is the roof drainage system.This sloping pipes through which water will go below, without stopping on the roof.

Such surface drainage is best done from plastic or metal.You can buy ready-made or make it yourself, if you have experience.

surface drainage can be on the ground - it will collect water in the area and divert it into the sewer.

Such surface drainage make follows: tube placed in shallow ditches around the foundation so that the pipes are completely underground.

pipes should be removed off-site.

Thus, surface drainage are doing all around the house - ring method is the best protection against moisture.

drainage device around the house - a necessary measure to protect and maximum service life, so do not neglect this measure.And perform circular drainage around the house with their hands quite force using the above instructions.
