Concreting the site: reinforcement, installation of

Building

Filling the site with concrete is not particularly difficult and it is quite within the power of any home craftsman. But in order for the result to be pleasing to the eye, to be of high quality and durable, compliance with the work technology is required. About her and will be discussed below.

Concreting

Advantages and disadvantages of concreting

This process allows you to create a platform that:

  • has an attractive appearance - with its help, you can create a cozy area, especially if you provide space for beds, benches and other decorative items;
  • is firm and level - it will not form pits, bumps or ruts. The latter is especially true for those places where the road will go;
  • easy to maintain - its surface does not create dirt and grass does not grow on it, which must be mown.

The disadvantages of concreting include its complexity and the need for significant financial expenses. This is especially true when, in addition to purchasing materials, you plan to hire workers. So, the cost of concreting the site is an average of 2500-3000 rubles per 1m ?.

To achieve the desired result, it is necessary to properly carry out all the necessary work. Let us consider them.

Concreting process

Preparatory work

First you need to mark the future site. This is done with the help of hammered pegs and a rope stretched between them. Further, to a depth of 25 centimeters, a fertile layer of earth is extracted. Throw this soil is not worth it - it can be useful for use in the greenhouse or in flower beds.

If any communications pass through the construction site, they must be protected. To do this, they are placed in a box or pipe. Then the ground is leveled and compacted.

The next step is the creation of formwork. It is built from boards, which are reinforced with pegs and struts. This structure is mounted so that its upper edge is flush with the surface of the future site. The correctness of placing the formwork is checked using the construction level.

Formwork for the site

After that, the bottom of the plot is covered with geotextile. This is the name of a special material that allows moisture to pass in one direction only. Its use will prevent the removal of moisture from the solution into the ground.

Another preparatory stage, which our instruction envisages, is the creation of a sand-cement pad. At first, a layer of wet sand 10 centimeters thick is piled and compacted. Above the same layer of gravel. He, too, should be tamped.

Tip! If the site closely adjoins any structures, then a gap must be left at the point of contact. This is due to the fact that when heated, the concrete expands somewhat and, if it is closely adjoined to foundations or other structures, can damage them.

Reinforcement

Creating a quality coating is not possible without reinforcement. For this you can use reinforcement or wire mesh. The second option is simpler, but it is suitable only for the surface on which there will not be significant loads. In this case, a grid with cells of 200 * 200 or 100 * 100 millimeters is used.

If we are talking about creating a platform for a car, then it is better for it to apply the first option, namely, reinforcement. Its price is higher than that of the wire, but, at the same time, its carrying capacity is higher. For work, select samples that are about 10 millimeters thick.

The reinforcement cage is created as follows. At first, the rods are laid in the longitudinal direction, and then in the transverse direction along the entire perimeter of the site. Then, at the intersection, they are connected to each other with soft steel wire.

Tip! Do not use for welding connections. Because of it, the frame will be very tough, unable to adapt to the ground. This will cause cracks on the surface of the concrete.

Installation of beacons

In order to obtain a smooth surface as a result of pouring, it is necessary to use beacons. So called guides, which are installed on the concreted area. As these are used metal profiles ud, which are usually used for the installation of drywall. They are perfect for the role of lighthouses and, moreover, their cost is low.

Install them as follows:

  1. cement mortar is prepared - it is created on the basis of a calculation of 1: 4, where 1 is cement and 4 is sand;
  2. slides are formed from the prepared mixture located in several rows;
  3. lighthouses are placed in the placed lumps - their location is checked and corrected with the help of the construction level.

Answering the question of how to properly concreted site, it should be noted that the distance between the beacons should not exceed 1m. This will make the subsequent work on leveling the filled solution more convenient.

In addition, it should be noted that the transition to concreting the site is possible only after the cement slides are completely frozen. Otherwise, the guides attached to them may move to the side.

Preparation and pouring concrete mix

Mixing mortar in a concrete mixer

To prepare the solution used concrete mixer. First, water is first poured into it. After turning on this device, cement is gradually poured into it, and then rubble.

This sequence allows you to get a good mixture that does not contain lumps. Knead it for 15-20 minutes.

As for the concrete proportions, they depend on the type of concrete used. She, in turn, is selected based on the purpose of the site being prepared and its required strength.

So, for the pedestrian walkway will be enough of the M100. To fill the courtyard is better to use the brand M200 - it is more durable. The proportions of these mixtures are shown in the table below.

The proportions of the concrete mix

The finished solution is poured on the platform and leveled between the lighthouses. For this, a special tool is usually used - the rule. In his absence, the same can be done with an ordinary flat rail.

Leveling mortar

Tip! If there are still defects on the coating, then for their accurate cutting it will be necessary to cut the reinforced concrete with diamond circles. Diamond can be used to remove small irregularities with your own hands.

In conclusion, another important point should be mentioned. Concrete must lose moisture gradually, otherwise it will crack. To avoid this, after the water evaporates from its surface, the pad should be covered with polyethylene.

Conclusion

To create a concrete platform, you first need to clear a suitable area, install a formwork on it, then reinforce, install beacons, pour concrete solution and level it. It uses the composition of the brand M100 or M200.
