How to make a ditch along the fence with your own hands: Instructions + Video Arrangement of a drainage ditch along the fence. In fact, it is not so difficult to arrange a drainage ditch along the fence to drain water. It is important that you choose the optimal format by which you can prepare a drainage ditch near the fence,


and also determine how much and what materials will be required.

General information

Why do you need a ditch

In a private house there are such problems that are definitely required solution:

  • How to make a ditch along the fence with your own hands: Instructions + Video In areas with a lot of precipitation, soil erosion occurs.
  • If the groundwater is high, then the soil is waterlogged on the site.
  • If there is a natural slope, then all the water from the site will accumulate in the lower part, will begin to "pull" the fertile layer of soil.
  • In mountainous and hilly areas, depending on the season, a large amount of water may fall on the site from the area located higher up the slope.

  • Precipitation from the atmosphere on the road surface begins to accumulate and drain under the fence around the entire perimeter of the site, and this can wash away the foundation and even the supports of the fence.

In all situations described above, the only optimal solution would be to create a drainage ditch or a hidden drainage system around the entire perimeter of the site. The main task of the ditch along the fence is to collect surface sediments and remove them from the site.

At the same time, it will not be used to transport excess water, rather, on the contrary, it is a localized drainage field, where excess moisture can accumulate and it will gradually begin to be absorbed into the soil, while not bringing negative consequences for buildings and fertile topsoil.


There are three types of drain:

  • Open.

  • Closed, perforated pipes are laid and filled up.
  • Backfill, the ditch is first filled with coarse gravel, as well as with filtering bulk materials in order to quickly drain water.

To create a ditch along the fence around the entire site, it is easiest to use open drainage ditches from the outside, which will have a reinforced slope and a stable slope. In this case, all excess moisture from the site and adjacent areas (even from the road surface) quickly went into the depths, where groundwater is deposited or moved to a drainage field / well.

The main advantages are the following:

  • A minimum amount of materials is required.

  • Small amount of land work.
  • A wide range of ways to strengthen the slopes.
  • An easy way to keep the area in good condition, cleaning and maintenance.

Now let's talk a little about the requirements.

Requirements for placement

Normalization is performed for any drainage systems that are focused on reclamation of a private area according to SP 104-34-96, as well as SNiP 2 .

05.07-85. The optimal slope should be negotiated in order to organize a drainage ditch, the distance to the fence, as well as other structures. In addition, you should select the version depending on what value of the throughput is required and what are the characteristics of the drained area, for example, the type of soil, the general slope, etc.

For a plot with a flat surface and a minimum slope of up to 5 degrees along the horizon, the additional slope at the bottom of the ditch should be equal to 3 to 5 ppm, and this will correspond to a difference in height from 3 to 5 cm for every ten meters.

In fact, the quality of the made slope and the uniformity can be determined on the spot, during the preparation of the trench. In addition, it is difficult to ensure the shape of the trench with high accuracy, therefore, when operating the drain, its geometry will have to be corrected.

It is important that the drainage ditch is located away from the fence posts and support structures so that the base is not washed out. It will be enough to move the upper border away from the plane of the fence by approximately 0.3-0.

5 meters, and during the arrangement and strengthening of the walls, make the soil denser so that water in the future could not get under the fence.

Details of the question

Several ways to strengthen the walls

Arrangement of a ditch along the fence only in which -to a measure will play the role of a transport system, and the water that will enter it must be well absorbed into the ground along its entire length at the bottom of the ditch.

The use of concrete sections or other means of reinforcing the bottom will be impractical. It is also allowed to use a waterproof rigid base, but only if underground communications will pass under it, which must be surely protected from precipitation and water in the ground.

Here are the methods that are effective for strengthening the slopes:

  • How to make a ditch along the fence with your own hands: Instructions + Video Dense plantations with a well-developed mealy root system.

    In this case, perennial low-growing plants, grasses, etc. for slopes up to 30 degrees are ideal for you.

  • Geomats , which are nothing more than networks of polymeric materials with large cells that are stacked in several layers. They will not interfere with the growth of green spaces, but at the same time, they will protect the soil from convergence and erosion in areas where the slope is up to 70 degrees.
  • Biomats are special porous and cellular polymer webs with a large thickness, which have places for filling soils and perennial seeds.

    Suitable for areas with a slope of up to 60 degrees.

  • Large reinforced cubes made of galvanized steel wire mesh or polymer material, to which are filled with drainage materials for backfill. They are used to erect deep ditches with steep walls in mountainous terrain, and if there is a large depth of groundwater, there is a clay layer close to the surface, which prevents the removal of precipitation.

When carrying out excavation work and preparing the foundation of the ditch, a pit should be dug with a great length and approximately 2 times wider than required. The material should be poured along the bottom and a cushion made of gravel and coarse sand should be made.

The slopes are compacted manually or mechanically, and then covered with a material that has been specially selected for reinforcement.


So that the arrangement of the drainage ditch along the fence is not done in vain and cope with the tasks, the following important recommendations should be followed:

  1. The depth of the ditch along its entire length should be slightly greater than the depth of the foundation located near the buildings, by about 0.3-0. 5 meters.
  2. Slope along the entire length, taking into account turns or bypass around the perimeter of the site, which will direct water to a single point or along the deepest border of the site.

  3. The slope should be determined by the composition of the ground and the calculated capacity and be located in the range of 1-5 cm for every 10 meters of length.

If there is a drainage well that departs from the drainage ditch contour, it is better to take the extreme one extending farthest from the drainage system well and calculate the deepening, and then calculate the control point. Everything should be located along a route that will be used in order to derive the correct geometry of the ditch.

How to make a ditch along the fence with your own hands

It is not difficult to create a ditch with your own hands to drain water, even if you do almost all the land work yourself. But the difficulty will be caused by the fact that there will be a lot of raised soil, and it will interfere during the work.

For this reason, it will need to be removed to another place, and it can be used to make a front garden around the entire perimeter of the site in such a way that it is raised above the ground level. It will be much easier to use the option where reinforcement is required with biomats, mesh, geomats or geotextiles. In this case, it will not be necessary to moisten the soil too much for the base, and it will be possible to limit ourselves to a small amount of loose drainage, gravel or sand, and this will significantly help reduce the load on the performer.

Cost of work

It will be possible to make a drainage ditch efficiently, quickly and beautifully if you are ready to pay for the use of heavy rafter equipment.With a minimum volume, you will need to hire a driver with an excavator who can dig the base for the ditch in a few hours and at the same time it will be easier to correct the shape and geometry of the slopes, the depth at the base.

The executing company will be able to carry out the preparation of the project of work and the estimate in advance so that you do not think and do not guess in terms of the final cost of the work in fact, and you can count on a guaranteed result.

The main burden on the budget of such an event is the creation of a drainage well, if it is required, and the rest of the work will come out to you relatively inexpensively.
