What will the work consist of?

It is worth noting that it is better to build a porch with the house. Then the house and porch will have a single base and waterproofing. But, if the porch is attached to the finished house, it is worth remembering that it should be 5 cm below the door. In addition, it can have steps, it depends entirely on the height of the entrance to the house.

You do not need to have any special skills in order to build a porch made of concrete. You only need to buy building materials. The construction takes place in several steps:

  • site preparation;
  • calculation of sizes;
  • manufacturer of formwork;
  • formwork installation;
  • completion of formwork;
  • concrete laying.

Preparation and necessary calculations of

Before starting to build, it is necessary to prepare the platform. If earlier there was already a porch, then it should be completely cleaned and cleaned this place. In order to lay the foundation, it is necessary to dig a pit 20-30 cm deep, the width of which should be 2.5 cm larger than the entire area.

Then fill a layer of gravel, and on top a layer of sand. For sand to fill the voids between the rubble, it should be spilled with water. After the pillow is made, you can start making the porch.

For this, first measure the distance from the ground to the bottom of the threshold. This will be his height. Steps for the porch of concrete should be about 15 cm wider than the door itself. A site, which in combination will be the top step, should have, at least, a meter depth. So it will be safer to leave home.

And here to calculate the height of each step, you need to divide the height of the porch into the expected number of steps. To calculate the width of the tread from 45 cm, subtract the height of the step.

Building a porch - mastering the basics of construction in a miniature

After all calculations have been made, we can begin the manufacture of formwork. Its height should exceed the height of the porch by 30 cm, because they will go to the ground. If the soil is strong enough, the height of the formwork needs to be made only 20 cm more. Now, on the plywood, draw the side brushes of the formwork.

First the risers and treads are drawn at a right angle, and then the playground and treads with a slope of 6 mm to 30 cm depth for water drainage. After that, they draw with a gradient of 15 degrees forward risers. To the lateral parts of the formwork are fastened the stiffeners. The prepared boards are mounted 1 cm from the building wall. At a depth of twenty centimeters, stakes are hammered at a distance of 45 cm from the notch.

Between them and the formwork are struts. After all this, the base layer is filled with 10 cm and carefully packed. The pieces of boards are cut according to the size of the risers. Their lower edges should be made inclined so that after pouring of concrete it is possible to eliminate irregularities. To the formwork, boards are nailed with nails with a double hat.

When the formwork is ready, cover the roofing material with the roof of the house, then apply a layer of sealant. It creates a temperature suture. To prevent sticking of concrete to the structure, the inner wall of the formwork must be coated with grease.

Concreting the porch is best done immediately from the tray. For this, it is necessary, if possible, to fit the concrete mixer directly to the porch. If it does not work, then you have to transport it with a wheelbarrow. Begin laying the porch from the bottom step. And only then, after erecting the first, you can take on the next. Continue in the same order.

If the formwork boards begin to bend under the pressure of concrete, then they should be fixed with one more supports. When laying it is recommended to overfill the steps with concrete and fill each corner so that no voids form. The concrete surface is to be further finished, and then kept for a week. And only then formwork is removed.
