The Foundation is the most important part of any structure, be it a house or a regular fence. That building stood for many years, the Foundation must be solid and reliable. Installation of the Foundation specialists in this area, but with your hands its very easy to do, especially if it is the Foundation for a fence.
Typically, the fence poured continuous footing is a strip, which is a closed rectangle outline, filled with reinforced concrete, providing stability and even weight distribution of the structure over the entire area of the Foundation. There are two options for the fill strip Foundation under the fence is to hire a professional or do it yourself. The cost of the fill varies from 15 to 30 thousand rubles. Cheaper to fill on their own. How to fill strip Foundation under the fence, we will tell our article.
Strip foundations are usually divided according to the depth of backfilling:
- slightly deepened;
- globalsupply.
Intake will fit a belt slightly deepened Foundation.
The types ↑
In addition to the types and even distinguish the types of strip Foundation:
- brick. First, in the pit filled with a solution of approximately 5-6 cm deep, is placed after the brick or stone. It should be noted that for stone need a layer of the solution is less than for a brick;
- quarry. When using this type of strip Foundation will need more sand, as each layer booth should be compacted with sand for greater strength;
- rubble concrete. This species is considered the most durable and long lasting. The filler can be any broken bricks, rubble, broken stone (granite, limestone).
The work plan ↑
At the initial stage, you need to have a clear plan of action to follow which you will be throughout the fill. This is necessary in order not to forget anything in the process. Rough plan looks like this:
- preparation of all necessary tools;
- procurement of necessary materials;
- the development of the design drawing;
- the marking of territory;
- preparation of the trench;
- preparation of formwork and its installation;
- installation of the reinforcement cage;
- concreting;
- the completion of the installation of strip Foundation.
Consider each stage read more.
Training tools ↑
To fill the strip Foundation, you will need:
- iron, it is better to use a sheet;
- boards or plywood, as an alternative, you can use sheets of OSB;
- roulette;
- superna shovel;
- mixer;
- level;
- reinforcing bars;
- wooden hammer;
- welding machine;
- fishing line or rope if there is nothing suitable, you can use the wire;
- trowel;
- building a simple pencil;
- electric jigsaw;
- plastic film;
- screws.
This is a sample list of necessary materials. It can differ from the one you make yourself.
The purchase of materials for mixing the foundations ^ the
When buying concrete and binder purchase only quality materials, the savings in this case are not relevant. So, you will need:
- cement, better if it is Portland cement or a cement grade M-500, characterized by a special fortress;
- gravel or crushed stone;
- water;
- sand.
All the ingredients are mixed either in a concrete mixer or in a large trough. If neither one nor the other, on the ground, having spread a roofing material or film. It is better to have a special «the dishes».
The development of drawing design ↑
In order to make a drawing, you must know the dimensions of the fence. You also need to determine the type of strip Foundation – for each species has its own depth. So, the necessary measurements:
- the length of the fence;
- the width of the fence;
- the depth of the Foundation;
- the diameter of the pillars.
The marking of territory ↑
After you have built the drawing, it is necessary to carry out the marking of territory, to dig the Foundation. Previously on the site of the future fence wikicite all stumps and weeds, remove all debris. For marking hammer stakes into the areas where you plan to install the fence. To stakes tie a rope or thread. This simple device will help you to make a layout exactly. It is on the correct markup depends how you install the fence.
Preparation of the trench ↑
The depth of the trench depends on the weather conditions of your region. So, if you are in the southern part of our country, the depth of the trench should be approximately 70-85 cm for other regions when calculating the depth of the trench should start from the depth of soil freezing. Once you have decided on the depth of the trench and the layout, feel free to dig.
Preparation of formwork and its installation ↑
After you have dug the trench, you can begin the construction of the formwork and its installation. In order to construct the formwork, you will need:
- boards or plywood;
- a simple pencil;
- roulette;
- chainsaw.
The basis of the formwork is the Board thickness of 25-30 mm. of boards constructed panels, which later built a kind of box. She needed to throughout the curing of the strip Foundation held its shape. The length of the casing will be equal to the length of excavated trench.
Installation of the reinforcement cage ↑
Installation of rebar is produced almost simultaneously with the installation of the formwork. Before installation, assemble the frame of the armature, so as to establish the right frame. If you don’t have a project frame, nothing to collect it in the following way: attach between a vertical and horizontal reinforcement rods by welding. The number of bars both vertical and horizontal depends on the depth of Foundation under the fence. Accordingly, the deeper strip foundations, the more you need rods.
When welding of reinforcement follow the step of rebar – distance between the horizontal bars. Typically, the step does not exceed 30 cm.
Concreting ↑
After installation of rebar we can start pouring the Foundation. It is best to distribute the concrete evenly, with a layer of about 15-25 cm, scattering it with a shovel, or pouring of concrete mixers. Be sure the concrete should be placed tightly to avoid air cushions. To avoid the formation of voids periodically prostukivanie the formwork. So the concrete was solid, the height of its jets (if you’re using the mixer) must not exceed 140 cm. it is Better to make a gutter on which the concrete will flow directly to the place fill.
To correctly calculate the strip Foundation under the fence, use a special calculator:
Completion ↑
After you have filled the strip Foundation, leave it to harden. For full «maturation» need, on average, 28 days at a temperature of 15-18 degrees. But if the days are warmer, you will solidify the Foundation, therefore, faster.
In order to install a fence with brick pillars on a strip Foundation, lay the waterproofing and make sure to layer between the brick and the concrete. This is necessary to ensure that the bricks didn’t collapse under the weight of the fence. To reduce the impact on the brick, enough to enclose the iron corners, or completely make metal support. So you can see how to make a fence with brick pillars, we suggest you to view the video:
If you want to install a fence of corrugated Board, this is no big deal. The corrugated sheet is light and strong, so before installing it does not require any additional fortifications. Invite you to view video for installing a fence of corrugated Board:
