Concrete stairs - durable and durable. That is why they are found in almost all types of buildings - intended for private life, in industrial and commercial premises with high traffic. The reinforced concrete structure is able to withstand high loads, and the use of modern building materials and competent design miscalculation makes it almost eternal. The manufacture of concrete stairs is in demand among far-sighted property owners, which is ensured by their many advantages:
A variety of forms and styles.

Moisture resistance; Low noise; Fire resistance; Strength; A variety of forms and styles. At the same time, the production of concrete stairs is affordable for a wide audience.
Types and forms of concrete stairs According to the type of construction, concrete stairs are divided into 2 types:
Direct - an inexpensive and easy to implement form, but requires a lot of space. Depending on the conditions, the installation technique may vary. The easiest way to mount a staircase is between two walls that serve as its support. It is more difficult to implement a design with support on one wall, or without it at all. In addition, a straight staircase can have from 1 to 3 marches, which expands the possibilities of its use in rooms with any layout and decorative decoration.
Spiral - this type of stairs is compact and has enhanced decorative properties. The spiral design is carried out in various forms and fits into the interior of any room. However, its external beauty requires a special approach to design and manufacture. For the formwork of the curved staircase, individually manufactured panels are used, the method of knitting the reinforcing frame is different.
Stages of manufacturing concrete stairs
The installation process of a monolithic staircase has many features, depending on the chosen form and working conditions. But, the general procedure for carrying out work is similar in various cases and is divided into the following stages:
Design - the primary stage of construction is the calculation of the entire structure. A drawing is being developed indicating the dimensions and the angle of the stairs, the width, the height and the number of steps; Assembly of formwork - a wooden structure that serves as the basis for further pouring concrete. At this stage, special accuracy and accuracy in the measurement of the dimensions of the structure is required, based on the design drawing;
Knitting reinforcement - an iron frame, which serves as the basis of a concrete structure and ensures its strength. The size and type of iron base is determined individually for small and large stairs;
Concreting - concrete of a class not lower than B15 is used for pouring, the consistency of the mixture is maintained. To avoid leakage from the formwork, the solution is mixed with large gravel from 10 to 20 mm in size. After pouring, the tamping step follows - with the help of a construction vibrator, air bubbles are removed from the mixture in order to avoid uneven subsidence and loss of strength. This is important because concrete that is only 1% less compacted loses strength by 5-7%.
Upon completion, you should carefully look after the mixture and control the drying rate - it is covered with polyethylene and periodically moistened; Formwork removal - the formwork is dismantled after the concrete mixture is solidified, but these works should be carried out with caution. If you remove the structure too early, the risk of collapse of the stairs increases. The formwork of the steps and the flanging are removed after 7-8 days, the supporting boards and the lower part - not earlier than after 3 weeks;
Finishing - after removing the wooden frame, the concrete surface is sanded and plastered. On the prepared smooth base, the finishing coating is laid out - tiles, carpet, linoleum, porcelain stoneware, wood or other materials.
