Why concrete staircase steps collapse
A well-built structure that is produced using quality materials and technology can function dependably for many years before needing any additional maintenance. In actuality, though, the opposite frequently occurs: a private home’s concrete staircase, constructed no more than three years ago, started to show chips and cracks.
Defects in concrete can arise for a number of reasons, including:
- low-grade raw materials for concrete mix;
- the wrong type of mix was selected;
- low quality reinforcement;
- inappropriate class and diameter of reinforcement;
- error in the calculation of the structure;
- cement not suitable for laying (lost activity);
- violation of technological processes;
- the manufacturer incorrectly installed the flights of stairs;
- external factors of an aggressive nature;
- impact on concrete of too low air temperature;
- mechanical damage to the structure.
Gaps in technology are the primary cause of repairs. Concrete compaction or early formwork removal, for instance, were subpar.
With the correct equipment and advice, anyone can tackle the practical and affordable solution of fixing concrete stair steps themselves. This post will guide you through several techniques for repairing common problems such as chips, cracks, and uneven surfaces. It will include step-by-step instructions and advice to make sure your repairs are secure and long-lasting. All the necessary options are available to return your stairs to their original state, regardless of whether you’re a do-it-yourself enthusiast or a homeowner trying to save costs on repairs.
Various degrees of damage
A thorough analysis of the flaws is always done before any repairs are made. The extent of the damage must be determined after a thorough inspection of the structure. Minor restoration might not be sufficient in the case of significant damage to steps caused by technological errors or the use of subpar mortar. In these situations, it’s crucial to enclose the steps with steel corners or start the restoration process by filling the prepared base with concrete-building mixture.
Without the need for specialized tools, the majority of damage is easily visible upon careful visual inspection.
Among them are:
- chips and potholes on the surface;
- rubbing (abrasion) of the top layer;
- protruding reinforcement parts;
- cracking (due to partial subsidence);
- stratification of the material (the concrete has lost its strength).
Minor flaws such as small potholes can be fixed on their own, but faults that have an immediate impact on the structure’s strength and stability should ideally be left to the expertise of trained professionals.
Rib of steps
Since this section of the staircase bears the brunt of the weight when in use, rib repairs are frequently required. This type of damage is particularly evident on heavily trafficked staircases, such as those found at home and public building entrances.
Repairing involves multiple steps:
- With a circular saw (grinder) at a slight angle, carefully cut the places around the deformations (in the direction of the depth of the step).
- Using a sledgehammer, remove the remains of concrete.
- Carry out installation of formwork so that the edge acquires a pointed appearance. To do this, the board must be lubricated with oil, its width should correspond to the height of the step. Apply the board to the vertical side of the step and on the site that is to be repaired, make a backup for fixation (type of pin).
- Next, apply a layer of primer with a brush.
- Fill the voids with a trowel with a construction mortar.
- Remove the board and round the rib using the step flight.
Use mixtures that are resistant to moisture to repair the concrete steps on the porch. Make a porcelain or tile cladding to lessen the amount of wear on the steps.
Treak
The steps’ horizontal surface is less prone to chipping, but friction on this portion of the structure is constant. They develop as a result, and need to be fixed. When abrasion removes the concrete’s protective layer, the issue becomes dangerous. The concrete material on the tread runs the risk of delaminating if this kind of destruction is not removed quickly; in this scenario, you will need to realign the steps and apply protection.
- First, you need to clean the surface of the stairs from dirt and dust.
- Then thoroughly treat it with a primer.
- Build formwork (boards in a vertical position).
- Pour a thin layer of concrete mortar onto the tread.
- Smooth it over the entire working surface.
The formwork can be taken down as soon as the concrete has solidified. Only once the concrete mass has fully bonded can the stairs be used.
Restoring corners
Periodically, chips in the corners show up on the porch and on the steps of closed stairs. In the latter instance, water exposure causes the corners to deteriorate more frequently.
- Clean the chipped areas on the corners with a metal brush.
- Using a brush, apply a layer of primer to the damaged area of the step. Also, the fallen concrete particle is treated with a primer.
- Use a trowel to apply mortar to the chipped area and press the broken piece of concrete.
- After the initial adhesion with pins or strapping, the surface is tightly fastened.
- After complete drying, the pin/strapping is removed.
Treating chips along the edges with tile glue or regular PVA glue is advised to improve the adherence of the work surface’s components.
Surface chips and potholes
Only when the cracks are tiny—about 25–30 mm deep—can surface damage be repaired with high quality. A hammer drill or impact drill is used to artificially deepen damage that is smaller.
- The work surface is cleaned of dust and dirt.
- The depression is primed twice with a frequency of 30 minutes.
- A cement solution (or a special moisture-resistant mixture) is placed in the depression and carefully leveled with a trowel.
An hour later, a thin layer of dry cement can be sprinkled on the still-wet surface and then gently rubbed into the mortar. This kind of manipulation will lessen the degree of abrasion of the protective layer and increase the step’s resistance to new damage.
Calculation of concrete composition
The strength of the staircase structure depends on proper proportions, so it’s critical to follow instructions rather than being lazy. For these purposes, you can use an online calculator (found on practically all websites related to construction), which will determine how much water, sand, and crushed stone are needed for a given volume of cement (of a particular brand).
Repair of damaged steps
There are various options for restoring a damaged staircase through concrete step repair, which helps the structure regain its original appearance and functional features.
Repairs are completed utilizing:
- formwork;
- facing;
- polymeric materials.
Formwork is used for repairs when chips are the result of a mechanical impact (something heavy falling). The cladding is used where there are minor cracks, which are frequently covered up by tile cladding (tiles have a disadvantage of their own: they become slick and possibly hazardous when they come into contact with water).
Minor flaws can also be filled with polymer material, which is far more dependable than tile coverings. It looks fantastic as cladding, is simple to install, and "refreshes" the steps. You can use the stairs safely even in the presence of moisture because the polymer cladding does not slip (see step-by-step instructions for each type of work below).
Mixtures for repairs
Dozens of varieties of dry mixes in different proportions are available on the current building materials market for fixing concrete structures. You can use the manufacturer’s "Nanocrete R3" mixture for low-cost work (subject to minor damage), BASF. About 75–80 rubles will buy a 1 kg bag of the mixture (the mixture consumption for a 1 mm thick concrete layer is 1.5 kg / 1 m2).
When doing extensive work, the
From the producer "KREPS" is appropriate. The material costs about 370 rubles per 25 kg bag (consumption: 1 kg per square meter for a layer thickness of 1 mm).
As a counterpart, you can utilize the
Producer "Khrustalnaya Gora". Costs approximately 930 rubles and is available in 25 kg bags (consumption: 100 kg per m2 for a thickness of about 50 mm).
Positive evaluations were obtained by
From REMMERS, the manufacturer. The material is available for purchase in 5-kg little packages, each costing roughly 2400 rubles. 1.7 kg per square meter of consumption for a 1 mm layer thickness. Therefore, the more layer that is required, the more mixture will be consumed.
Reconstruction
The task of completely restoring steps is one that nearly every homeowner must undertake if they hope to keep the stairs’ original appearance without having to purchase a new building. Restoration of concrete steps is helpful when it is not always possible to replace a flight of stairs with a new model.
Prior to starting work, the stairs must be thoroughly inspected for damage and the true extent of the reconstruction must be determined. It is best to speak with experts if the structure has historical significance.
You will be given a comprehensive inspection report for the structure, which you can use to calculate the necessary supplies and create an action plan for restoring the steps. Following that, you can safely get down to business as long as you adhere to the technology. It is only under these circumstances that the reconstruction will be successful and cost-free.
How the repair is carried out
Let’s begin with the traditional formwork-based version. The following is how the repair is done:
- It is necessary to make something like reinforcement using screws and dowels (screw in the parts at different angles).
- For the construction of the formwork, even and straight boards are used. They need to be well fixed on the work surface so that after pouring concrete the formwork does not “part”.
- We impregnate the formwork with water. This will prevent moisture from concrete to wood. After the harvest, pour a concrete mixture.
- The flooded mixture is carefully tamped to eliminate the appearance of air bubbles inside the mass.
The staircase can be used immediately after the concrete is firmly clamped, or it can be worked on further using tiles or polymer material.
Restoration of concrete steps
Making a thorough material estimate will be essential to restoring the original functionality’s steps and preventing extra expenses along the way. You will need specialized assistance if you suspect serious destruction, but if the steps are just minor damage, you can repair them on your own.
Use polymer concrete to smooth out small imperfections; it readily overcomes the drawbacks of traditional concrete.
Conversely, if restoring a sizable portion of the stairs is required, adhere to these guidelines:
- Using a hammer or chisel, remove the remains of cement stone and debris in the cracks of the steps, level the edges with the optimum striking force.
- Seal the gaps cleared of debris with the prepared concrete solution.
- After drying, the stairs are ready for use.
In the event that the step calls for total restoration, the following work will be done:
- Clean the surface from small debris, dirt and dust (with a hammer or chisel).
- Build formwork. Make a strong support so that the boards do not shift under external influence.
- Fill the damaged section/the entire cavity of the step with concrete mortar or a building mixture for repairing concrete steps, leave until the concrete is completely bonded.
Use a thicknesser when you need to give the steps a rounded edge. After removing the formwork, gently round the surface. Only a portion of the wet concrete has dried before the manipulation is performed.
How to repair steps covered with wood
The work’s technology is comparable to the earlier choices. The way the work surface is prepared is the only difference. Removing the facing carefully is crucial in this case to avoid damaging the concrete base or the wood. Only after the concrete has completely dried can the steps be refaced to prevent material deformation or partial destruction.
Possible options for facing steps to hide defects
Concrete steps will become more streamlined and smooth out small flaws when they are faced. Both hard materials, like laminate or tiles, and soft materials, like carpet and linoleum, are used for this purpose. The outer layer shields the concrete from damage and enhances its appearance.
Tile cladding
In addition to serving as a solid barrier to keep water and moisture out of the concrete reinforcement, the tile effectively conceals any potential flaws in the surface of the concrete. Remember that the abrasion and strength of ceramic and clinker tiles are several times higher than that of concrete.
- The steps are leveled and cleaned of dust and dirt.
- The tiles are laid with glue. For an even contour of the seams, it is necessary to use crosses (special fasteners).
- Finally, the seams are rubbed. The cladding is ready.
Use metal cutters or a grinder to cut tiles if necessary.
Laminate finishing
Only appropriate for indoor staircases shielded from precipitation, snow, and other environmental elements. Choose a material with at least 32 units based on the wear resistance class.
- Make the surface of the steps smooth using a special putty (you can use a ready-made cement-based mixture).
- Apply tile adhesive to the back of the laminate and secure it to the steps. Watch the thickness of the adhesive layer – it should not exceed 2 mm.
- Cover the corner joints and the side part with a decorative corner (made of metal or plastic).
Although they are not required, corners prolong the lining’s service life and shield the laminate from mechanical harm.
Paping with linoleum
The different patterns and hues of linoleum allow you to design a sophisticated stairway design. Finishing both monolithic and prefabricated structures is possible with this material.
- Level the steps. If there are undercuts, use a grinder to remove all irregularities. Pay attention to the tread and risers – they must be even, since linoleum will certainly reflect all the flaws.
- Clean the surface from dirt and dust.
- Trim with corners (protection from breaking and bending).
- Start pasting from the top step.
In the process, we advise chopping off pieces of linoleum so that you can adjust the parts to size if needed.
Facing with carpet
A typical choice for staircases found in homes. This material is nice to the touch and makes climbing and descending stairs extremely comfortable.
- The steps must be made even.
- The material must be cut to the width of the stairs and rolled into a roll.
- We start pasting from the top step, pressing the carpet tightly to the work surface (you can use a roller).
To maintain the external beauty of the finish, attempt to make the joints along the lower edge of the riser.
Wood cladding
Low slip and appears natural in most interiors.
To lower the fire hazard class of wood, the material needs to be impregnated with a fire-retardant substance prior to being clad.
- The step is leveled (it is not necessary to bring it to perfect evenness, since wood will solve this problem).
- We treat the wood with an antiseptic and lay waterproofing (it can only be glued in places where the wood will come into contact with concrete).
- We install a frame on which the cladding will be fixed.
- Along the structure, we assemble logs from slats (we prepare the flooring), repeating the shape of the steps. Every 4 steps, we connect the logs with longitudinal crossbars.
- We attach the frame parts to the concrete base every 2 meters using dowels.
- We sheathe the finished frame with a board or plywood.
- Finally, we apply a layer of varnish or paint.
An aluminum profile can be used as the frame’s foundation; however, self-tapping screws must be used to fasten the wood instead of screws.

If you take the right precautions and use the right tools, fixing concrete stair steps yourself is a manageable task. You can return your stairs to their original state by determining the extent of the damage, assembling the required equipment, and selecting the best repair technique.
Simple repairs with epoxy or concrete filler may be adequate for small cracks. You might need to pour new concrete for a more substantial repair or use a concrete patch compound for larger cracks or chunks. Prior to applying the repair material, don’t forget to thoroughly clean and remove any loose debris from the surface.
Using a form to hold the new concrete in place while it sets can help achieve a clean and long-lasting finish when dealing with broken edges or corners. To make sure the repair holds up over time, exercise patience and give it enough time to cure. Preventing future damage can also be achieved through routine maintenance, such as sealing the concrete.
You can prolong the life of your steps and save money by doing concrete stair repairs yourself. Your stairs can be safe and aesthetically pleasing again with the correct planning and execution.
