Yes, concrete can be grinded down. Grinding concrete down will happen for a variety of reasons, including resurfacing a floor or removing old sealers and coatings. Grinding is likely to produce large amounts of dust and debris, so it’s important to work with a professional that is equipped with adequate safety and dust-control equipment.
The process involves using an industrial grinder with a diamond grinding wheel to remove material from the concrete. Depending on the type of grinding being done, different diamond grits may be used for the grinding process.
The grinding process is often followed by a power floating step to smooth out any unevenness in the concrete.
How do you grind old concrete?
Grinding old concrete can be an arduous task, but it is necessary in order to create a smooth, level surface. To begin, you will need a grinder with diamond blades or a handheld sander. Once the grinder or sander is prepared and equipped with the appropriate diamond or abrasive blades or discs, you can begin grinding the concrete surface.
Start by slowly moving the grinder in a circular movement over the surface. This will help to remove any loose material and to level the concrete. As you work, check the concrete for any deep depressions or areas that are uneven.
If any are found, switch to a more aggressive grit of disc or blade to level the surface. Depending on the condition of the concrete, you may need to repeat the process several times to achieve a smooth finish.
Once you have completed the grinding process, sweep up all the dust and debris and then use a vacuum to remove any remaining particles. The final step is to apply a concrete sealer to the surface. This will help to protect the concrete and provide a longer lasting and durable finish.
How much does it cost to grind concrete?
The cost to grind concrete will vary depending on various factors, such as the size and condition of the concrete, the type of grinding equipment being used, and the amount of time needed to complete the job.
As a rough estimate, most concrete grinding projects will cost around $2 to $5 per square foot. However, larger projects may come with a higher price tag. For instance, if you need to remove several layers of epoxy, then you could be looking at paying up to $15 per square foot.
Additionally, you may need to pay more if you require specialty grinding tools, secure insurance, or secure a permit for the job. On average, most homeowners hire professional concrete grinders and pay around $150 per hour for them to do the job.
Is Mudjacking a good idea?
Yes, mudjacking can be a good idea depending on the situation. Mudjacking is a process that uses a mixture of soil, cement, and other additives to raise, or “jack up” sunken or uneven slabs of concrete.
It is an economical and durable alternative to replacing damaged concrete with new material. The most common applications for mudjacking are for driveways, walkways, patios, and garage or shed floors.
Mudjacking is a relatively quick and easy solution for filling in gaps and leveling the surface, and can often be completed in a single day, saving both time and money. Additionally, mudjacking is highly customizable and can be adjusted to accommodate different settling and soil conditions.
Although mudjacking cannot fix deep foundations or structural problems, it is a great option for quickly remedying outdoor concrete surfaces.
Is Polyjacking better than Mudjacking?
When it comes to comparing polyjacking and mudjacking, both are types of concrete lifting and repair services. Polyjacking offers numerous benefits over traditional mudjacking.
Polyjacking is a more effective concrete lifting and repair process than mudjacking. Polyjacking uses a polyurethane foam solution, rather than a gravel and sand mixture. Polyurethane is lightweight and can easily fill in empty pockets and provide a much stronger support for the concrete.
Polyurethane expands and hardens quickly and does not displace soil the way the mixture used in mudjacking does, reducing the risk for sinkholes around your home.
Polyjacking also does not require a hole to be drilled into the concrete, unlike mudjacking. Polyjacking is also less disruptive to adjacent structures. Additionally, polyjacking can be used to restore concrete on driveways, patios, and other difficult-to-repair surfaces where mudjacking is not an option.
Overall, polyjacking is a great option because it is less disruptive, requires no injections, and cures more quickly than mudjacking. It is also more structurally sound, which means it will last longer and provide a better repair and restoration of concrete surfaces.
How much does concrete grinding and sealing cost?
The cost of concrete grinding and sealing depends on several factors, such as the size of the area to be treated, the condition of the existing concrete, the materials needed, and the complexity of the job.
Generally, concrete grinding and sealing costs between $2 and $4 per square foot for basic grinding, prep work and sealing. For more complex jobs that may require additional labor, materials and tools, the cost can rise significantly.
Re-sealing every 2-3 years can increase the cost even more, as additional grinding and sealing may be required to keep the concrete in good condition.
How much does Mudjacking concrete typically cost?
The cost of mudjacking concrete typically depends on factors such as the size and complexity of the repair, the type of soil the slab is sitting on, the amount of material and labor required to complete the job, and the location of the repair.
Generally speaking, the cost of concrete mudjacking ranges from $3 to $7 per square foot. That said, larger and more complex jobs can cost as much as $10 per square foot. Generally, mudjacking is much cheaper than other forms of concrete repair such as replacing the concrete slab, so it can be a cost-effective solution for restoring the appearance and providing stability to the area.
What kind of grinding wheel do you use on concrete?
The type of grinding wheel you use on concrete depends on the type of concrete and the job you are doing. For general purpose grinding, a cup wheel is typically used, as this is designed to provide a fast removal rate on concrete, masonry, and other building materials.
If the concrete is particularly hard and abrasive, an abrasive stone wheel could be used, as this is designed to provide a higher level of removal. If the job requires a finer finish, a vitrified bond diamond wheel may be used.
This is designed to provide a smooth, low-temperature cutting action on concrete and other hard materials. Whatever type of grinding wheel you use, it is important to ensure that it is rated for the type of material you are working on.
How do you smooth out bumpy concrete?
Smoothing out bumpy concrete requires a few steps to ensure that the surface is smooth when the process is completed. The first step is to clean the area of any debris or dirt and remove any existing sealer or protective coatings.
If there are cracks, fill them with a quick-drying concrete repair product. Once this is done, you can use a concrete grinder to grind down the bumpy surfaces. This should be done with care so that the surface is even, with no high and low spots.
After the grinding is done, a concrete sealer should be applied to help protect the surface from future damage and wear. Lastly, a concrete polishing machine can be used to help create a smoother finish.
It is important to take the time to ensure that the entire surface is even and smooth before the entire process is completed.
How do you smooth cement with an angle grinder?
Smoothing cement with an angle grinder can be done by using the correct protective gear and being mindful of sparks and debris. To begin, make sure you have the required safety gear and the correct blades that can handle the concrete.
You will want to make sure to hold the angle grinder firmly and in the correct position, allowing it to slowly grind away the surface material to get the desired smooth finish. Move slowly to avoid gouging the concrete and make sure to move the angle grinder in even, circular motions.
After smoothing the surface, use a wet sponge to soften the raised cement and make any necessary touch-ups, then allow the cement to completely dry prior to sealing. Lastly, seal the cement to ensure the job is finished properly and increase the durability of the surface.
