A porch is necessary for almost every home, it not only allows you to solve functional, but also aesthetic problems of the building. It can be built by any person who has at least a remote idea of \ u200b \ u200bbuilding. Today we will talk about a concrete porch, which can be considered a capital structure, as opposed to a wooden one. In this regard, such a structure will take much longer to manufacture and will require more physical costs.
Foreword
The erection instructions are not very complicated, but this does not mean that they should not be taken seriously. Any stage of construction will require heavy physical costs, so immediately tune in this way, alas, but in this case you will have to sweat.
We recommend that you start by drawing up a general sketch of the structure. At the same time, it is very important that the reinforced concrete structure can organically fit into the architecture of the house. Otherwise, the front of the building will be damaged.
Usually concrete is chosen for capital structures, therefore, subject to construction rules, norms and requirements, they will serve for a long time not only to you, but also to future generations. An important factor in this is the ability of the material to undergo repair work at any time, including the use of facing material.
Using concrete will allow a porch to look equally good with a wooden structure when it can be easily sheathed with wood. You can also veneer it with wood-like siding, as a result of which the structure will look like an integral part of the building.
Technical requirements
Any construction should start with competent planning. To do this, first of all, you need to draw a detailed drawing, in extreme cases, a sketch is suitable. The construction of a concrete porch is simple, however, it is necessary to take into account many different nuances during the process.

| Flight of stairs | For movement on the structure by one person, its minimum width should be about 800 mm, if for two - from 1 m. Install handrails if the flight of stairs will have more than 3 steps. |
Below you will learn how to properly fill the porch of a house with concrete with your own hands. Specialists' recommendations will also be given.
Making the foundation
You should proceed directly to construction only after drawing up a drawing. Otherwise, the mistake of many non-professionals, you will have overruns of materials, as a result of which the planned price of work will greatly increase. You have to imagine with your own eyes what kind of porch you will get.
The foundation can be poured in several ways:
- A common monolithic reinforced slab is created for the entire area of the structure, however, the cost of the structure will be high in this case.
- Use the technology of the tape contour, which is located along the perimeter of the future porch... Fill the interior space with gravel or sand. The depth of the foundation for the porch should be the same as that of the main building.
Advice: it will be very good and correct for the level of the base of the porch to pass 150 mm below the freezing point of the soil in this area.
- The layout of a reinforced concrete porch before installing the foundation of the house is considered ideal.so that both constructions form one whole. In this case, no frosty heaving will be scary.
- If in your area the soil freezes deep enough, we recommend staying on a strip-and-column foundation... Supporting concrete pillars are installed below freezing of the soil to a depth of 300 mm, and a tape or slab is placed at a depth of 400 mm.
Tip: do not lean the porch staircase on the foundation of the house if you decide to attach the porch to the finished structure.
Otherwise, in winter, due to soil movement, both structures can collapse. We recommend making both monoliths independent.
- The bottom of the pit should be well tamped and covered with geotextile or roofing felt... Then make a pillow on top of a 100 mm layer of sand 50 mm layer of rubble and compact everything again tightly.
We mount the formwork
For this, sheet metal, thick plywood, OSB boards and wooden boards are usually used. The cost of metal formwork is high and difficult to work with, so wooden options are more often preferred.
Side sheets should be selected so that they can be immersed in the ground to the blind area. Then they are reinforced with struts and stiffeners. After installing the reinforcement cage, install and fix the strips limiting the riser.
We also recommend drawing the reinforcement cage scheme in advance in the sketch. It should be borne in mind that the structure must have 2 or more layers, which must be installed with a step of 100-200 mm. The optimal section of the rod is 12 mm, and it is better to tie them together with a wire, and not weld to each other.
Advice: make holes in the foundation in advance if it is supposed to dock the stairs sideways to it.
It remains only to fill the structure with mortar and wait 21 days until it gains strength.
Output
The concrete version of the porch should be used for stationary objects. Unlike a wooden one, during work you will have to expend a lot of physical strength. Before starting construction, make a drawing or sketch. The video in this article will provide an opportunity to find additional information on the above topic.
