A Concrete Patio is a really affordable structure that can be installed in a couple of days and that can give you a nice patio for your outdoor seating areas and grills. To create a long lasting patio, always make sure to install a 3" to 4" compacted gravel bed on top of a compacted surface. Concrete is a very unforgiving material, so make sure that the excavation, gravel base and all the wooden forms you might need are 100% ready before you start with the mix. There are three ways to obtain the concrete: premixed on a concrete truck, premixed on bags, or by mixing it on place from its base materials (Cement, Gravel and Sand). Remember to pour the concrete by areas, always finishing the top smooth before it dries too much!
Now installing patios and stone work on the areas of: Bethesda, Potomac, Chevy Chase, Rockville, Silver Spring, Gaithersburg, Germantown, Olney, Montgomery Village, Wheaton, Kensington, and many more in Montgomery County and Maryland! When building concrete stairs, especially inside your house, you have to use the right mix of concrete and install a proper amount and structure of reinforcing bars.
Before building the wooden form for the concrete stairs, we recommend you to get accustomed to the components of a regular star. Therefore you have to decide from the very beginning the dimensions of the treads and risers, taking into account the slope and the run of the stairs.
Remember that the height of the risers and the width of the treads should remain the same along the stairs.
In the image you can see the concrete stairs form, and the proper dimensions to use for the risers and threads. Use a spirit level, as to make sure the form is level and plumb, if you want to obtain a neat look. Work with patience and  make sure the wooden form is level and plumb, otherwise the concrete stairs would look misaligned.
In this image, you can see that the wooden formwork must be locked together tightly, using different boards and posts. A proper recipe for the concrete you have to pour in the formwork is the following: mix thoroughly 3 parts cement, 2 parts sand, 4 parts gravel and water.
Work with patience, as to make sure the structure of the wooden formwork is rigid and able to sustain the rebars and the concrete.
If you are not able to level the stairs perfectly, then you will have to pour a thin layer of self-leveling screed, after the stairs have dried out. Smart Tip: Wear rubber boots, safety glasses and gloves, as to avoid irritating your skin, while you pour the concrete.
The stairs need at least 4 weeks to dry out completely, so make sure you remove the forms only after it dries properly. Smart Tip: sprinkle water on the concrete stairs before brooming it, as to prevent the creation of dust.
In the image you can see how the concrete stairs look, after we have removed the wooden form. As we have already highlighted, you must vibrate the concrete, otherwise it will crack easily and might even not support your weight.

In addition, we must point out that the hight of the risers must be the same for every step, as well as the dimensions of the treads. From our experience, we recommend you to build a quarter space landing, as it will be easier to use by children and elders. We can assert that building concrete stairs is complex and there are many aspects which require knowledge and expertise in this field, therefore consult a qualified engineer before putting your life at risk. After you have built the concrete stairs and completed the rest of your house, you have to finish it, wither by installing tiles, carpet or by laying wooden treads.
Thank you for reading our article on how to build concrete stairs and we recommend you to check out the rest of our projects. If the concrete dries before you were able to finish it, the only real solution to fix it is to jack it out and rebuild. But if you want to give it a try, at least try not to make a very big patio as your first project. Which option is selected would depend on the amount of concrete, the use of the concrete and the workspace itself.
Building interior concrete stairs is a complex project, as you have to build a formwork, install a structure of reinforcing bars, pour concrete and finish the stairs with a float. Therefore, proper concrete stairs should be at least 3′ (90 cm) wide, as to be able to install the railings and still have enough space for a person to use it without any issues. In this manner, the stairs will support your weight and will resist for many years in a row.
Therefore, pay attention to optimal dimensions for interior concrete stairs and use solid wooden boards.
The wooden boards creating the steps, must be fastened with several screws to the lateral structure of the formwork.
We always recommend to our clients to pour the concrete ceiling and stairs in the same day, as to create a strong bond between these components. Use long screws and nails to lock together the wooden formwork and make sure there are no gaps between the boards. While pouring the concrete in the form, it will create a great pressure and might move the risers from their position.
Nevertheless, the ideal option would be to buy the concrete already mixed from your local concrete company and to pour it in the formwork with a pomp.
It is important to order the concrete only after you are perfectly sure the form is able to support its weight and the form it is level and plumb. Use a straight edge to spread the concrete and them use circular moves to give a nice finish, by using a polystyrene float. Work with patience from the top to the bottom of the stairs, making sure you vibrate the concrete (either with a concrete vibrator or by hitting the formwork with a hammer). You should be able to notice that the concrete is uniform and even over the whole surface,  and that there are no holes, pockets of air or cracks. In addition, the concrete stairs are at least 4-5” thick, as we have installed the rebar structure, which will reinforce the concrete.

In addition, as you can easily see in the image, in our case we have built a split landing, as we didn’t have enough space to construct a quarter space landing. We have to point out that we don’t recommend you to do this kind of project by yourself, but to hire an engineer and a qualified team of builders. Each of these alternatives is good if it is performed in a professional manner, so you should choose the one which fits your tastes and needs best.

Green Cross Australia's CEO Mara Bun admires Robyn Morris' new sustainable and fashionable home that she rebuilt following the Black Saturday bushfires. We really recomend a professional to install or just help you with your DIY concrete patio. As compared to regular wooden stairs, concrete stairs are more durable and rigid, therefore it is a perfect choice if you want less problems for many years in a row. In addition, the angle of the stairs is important when building them, as you should take into consideration the end users.
These are the standard dimensions for concrete stairs, as to satisfy the needs of many categories of persons. In addition, make sure you consult a structural engineer to comply with the local building codes. In addition, you have to observe the proper dimensions for the stair treads and risers, as to be able to use it easily. Just after you have filled the formwork with concrete, you have to vibrate it thoroughly, as to distribute it evenly and prevent the creation of air pockets. Remember that this step is essential, so use a hose to sprinkle water over the concrete at least every morning (it it is hot outside, you have to water it at least three times a day). Nevertheless, you should remember that you can build concrete stairs only in a masonry house, otherwise you won’t be able to secure it properly (you can build entrance steps for a wooden house, but not interior concrete stairs). If the stairs are to be used by older people, you should decrease the slope of the stairs (<30?). A concrete stair is an important part of your house, so we recommend you to hire a qualified construction engineer to design the plans.
Your paint will have to adhere to the concrete surface, and therefore, you need a perfectly clean concrete surface. Check the manufacturer instructions for applying and the drying time.Do not pay attention to hair thin cracks.
