7 Tips for Choosing the Right Concrete Contractor

concrete service

The role of concrete in the world today cannot be ignored. Most of the structures we see daily have used concrete as the primary construction material. As it stands, concrete is the most used man-made construction material in the world.

Whether you are interested in the walkway, patio, driveway, or any other concrete service, you must look for concrete grinding experts who understand their jobs. Because you want your concrete service to be done right, you need to make sure that you choose the right professionals. When hiring a concrete floor grinding contractor, here are some of the tips you can use to make the right decision.

1. Look for Experience

When you are hiring for any concrete service, you must consider industrial experience. Try to make sure that they have been in the business for more than five years, which will give you some reliability and stability. Experienced concrete service men will provide insight and handle technical works, which ensures that your work runs smoothly. Considering experience helps you to choose a contractor who will be able to provide the right ready mix concrete and additional concrete.

2. Verify Insurance

Concrete services can theoretically go wrong at any given time and you don’t want to be liable if that happens. Therefore, you have to make sure that the concrete floor grinding technicians you are considering have an insurance policy that can cover your project in the event of an accident. You also need to verify the insurance policy by verifying the coverage dates from the insurance provider. Verifying will help you to avoid an insurance policy that covers your project, at least partially.

3. Compare Prices

When you meet with concrete service contractors, they will typically present you with an estimate for the project. Compare quotes from different crack repair contractors and use the estimates to make a sound decision. However, it is important to make sure that you don’t get attracted to the lowest prices because you might be getting low-quality services. The key lies in making sure that you get concrete services at reasonable prices.

4. Search For Online Reputation

In the digital age, you don’t have to ask neighbors about the best concrete service provider in the locality. Thousands of concrete companies have websites where they have been getting feedback from their previous customers. Online reputation is reliable and very useful when choosing a technician. Consider working with the contractor who has high positive reviews. You don’t want your driveway to be handled by individuals who have been labeled unreliable by their previous clients.

5. Evaluate Customer Service

Professional customer services form the epicenter of any project. Therefore, when you are hiring a concrete service provider, you should make sure that you hire a technician who is punctual, respectful, and has good communication skills. You want to work with friendly people who understand your needs. For the project to be handled professionally, there needs to be improved human interactions. This is only possible in companies with good customer services.

6. Review the Company Portfolio

Before hiring for concrete raising, make sure that you ask potential contractors to present to you some of the previous portfolios. Most concrete companies will have, on their website or social platforms, a portfolio of the jobs they have handled in recent times. These are the images you should use to get inspired or to find out whether the work done is consistent with your needs.

7. Obtain Licenses and Certifications

Licenses and certifications are essential legal documents that you should consider before hiring a concrete leveling company. Both Federal and State governments provide licenses and certifications to the concrete companies so that they can operate in the country legally. Avoid dealing with unlicensed and uncertified companies because they might be missing on skills and equipment to professionally handle your project.

These are some of the factors that you should consider when you are looking for a concrete service provider. Choose a licensed and insured company that provides concrete services such as raising and leveling, void filling, concrete grinding, and crack repair among others.

What is Concrete Raising?

crack repair

Have you ever encountered broken, cracked, or damaged concrete areas? If you have, you’ll understand how unsafe it can be for you to walk on. This means that crack repair is required as soon as possible to ensure that the existing cracks do not cause more damage to the underlying concrete or serve as a potential source of injury for passersby.

Though there are many solutions to fix these cracks, one of the most popular and effective options is slab jacking. Also known as mud jacking or poly jacking, this is the process of adding more material to raise the level of concrete and to make it even and smooth. This cement raising option is a great alternative to a complete concrete replacement and can save you anywhere from 30% to 50% in time and costs. In other words, when you spot damaged or cracked concrete, simply fill the underlying area with concrete and raise the level so it becomes uniform.

How Does Concrete Raising Work?

In slab jacking, a small hole is drilled on your concrete and the material is poured through it. This makes the foundation sturdy and fixes cracks and holes at the same time. Later, concrete is injected to support and level the slab. After those steps are completed, the drilled holes are patched and smoothed out to give you a concrete area that looks almost like new.

Why Choose Concrete Raising?

Many advantages come with concrete leveling or raising and some of them are as follows.

Saves Time and Money

Traditionally, the best way to perform concrete crack repair is to replace the entire concrete area. But the catch is that this option is time-consuming and expensive. It may not be ideal for all situations, to put it plainly. Many times, such concrete replacements are out of reach for homeowners and small businesses.

In such cases, a simple crack repair is a better option, as it can be done within a short time and will cost only half as much as a concrete replacement. Unlike traditional mud jacking, where you need to wait anywhere from two to seven days for completion and restored use, you can use raised concrete immediately.

Minimizes Damage

Concrete raising reduces the possibility of damage to your yard or walkway because no heavy equipment is needed or used in the process. The only equipment that could possibly impact is a large hose pipe, but even that will not cause any damage to your lawn. Anything you can do to minimize further damage to the surrounding area can be considered a

Reduced Chance of Injury

Traditional crack repair options can take many days. During this time, there is always a possibility for your family members or visitors to get hurt. But with the right concrete crack repair services, you can complete the repair work within a matter of hours. The less time the job takes to complete, the less likely it will be for someone to get hurt.

Improves Ground Support

When you pour mud or pump cement to the ground, it further strengthens the foundation and ensures that your crack repair work lasts for a long time. By taking this small step, you can strengthen the area that surrounded the crack and make the entire piece of concrete last for a longer period.

Thus, these are some of the benefits of concrete raising.

Facts About Concrete Voids and Concrete Damage

Though concrete is a durable and inexpensive material used both inside and outside the home, concrete does not last forever. Cracked, uneven, or sunken concrete can occur for many reasons. In rare cases, damaged concrete results from ice, earthquakes, impacts, or overloading. More commonly, however, voids under the concrete are responsible for damaged concrete. When a void is responsible for concrete damage, concrete crack repair may be ineffective without first filling the void. Here are some facts about concrete damage and the process for repairing it effectively:


Voids are underground areas where soil is less dense and, consequently, able to support less weight than compacted soil. This fact is confusing to some people because the general view is that the ground is stable and should always remain so. However, voids under a concrete slab can be caused by a number of conditions:

  • Water flowing under the concrete slab causing soil erosion
  • Underground water flows dissolving limestone shelves and causing soil to collapse
  • Insufficient soil compaction before construction, exacerbated by the weight of the structure built on top of the uncompacted soil
  • Loss of lateral support due to nearby excavation, mining, or construction activity

The risk of voids can be reduced by properly draining soil around the structure and completely compacting soil before construction. However, some voids are, no pun intended, unavoidable. Voids due to dissolved limestone or subsidence probably cannot be prevented in any event.

Concrete Damage

Concrete is strong under compression forces, but weak under tension forces. Prestressed concrete, which has steel rebar embedded in a concrete slab, was designed to compensate for concrete’s weakness in tension. In tension, the steel bars bear the load so that the concrete does not need to. However, there are limits to the tension forces any concrete slab can bear. When those limits are reached, the concrete will crack necessitating concrete crack repair.

Imagine, for example, a concrete slab that is supported in the middle by compacted soil but has voids under each end. The concrete slab would be balanced like a see-saw, with both ends sagging. At this point, gravity takes over and the concrete slab will eventually reach a more stable position. The slab may pivot and slide laterally into a void, resulting in a raised or sunken concrete slab. Additionally or alternatively, the sagging ends will cause the concrete slab to crack in the middle.

Concrete Repair

Concrete crack repair is not as simple as filling the crack. Anyone who has used DIY concrete crack filler knows that filling the crack will be an ineffective form of crack repair absent filling the void that created the crack in the first place. Merely filling the crack will often fall short as a form of concrete crack repair because the crack will reopen as the concrete continues to sag into the underground voids.

The process used to fill concrete voids has existed for nearly 100 years. The process was formerly referred to as mudjacking or slabjacking because the process is exactly as the name implies – grout (referred to as mud in those days) is injected into the void, where it expands and hardens. Filling the void under a concrete slab with grout accomplishes a few important tasks:

  1. Injecting grout into the void densifies the soil, supporting the concrete slab and filling the void
  2. Grout expands, lifting the concrete slab and straightening it
  3. Grout hardens, preventing further soil collapse

There are a few different forms of grout used to fill voids. The “mud” version of grout is a mixture of water, cement, and a fine aggregate, such as fly ash or sand. The grout is usually looser than concrete, since the goal is to fill all the cracks and crevices in the void. As an aside, concrete and cement are not synonymous; cement holds concrete together but cement also holds grout together.

Another form of grout is polyurethane, a polymer. Polyurethane is delivered as a foam which expands and hardens inside the void. The primary benefit of polyurethane foam over cement grout is that polyurethane foam cures quickly and can be injected even when the soil is moist.

In sum, the most common cause of concrete damage voids under the concrete slab and, consequently, repair of cracked, uneven, or sunken concrete often requires that the voids be filled first.

When To Call For Concrete Crack Repair Services

If you’ve got concrete in your home as part of your basement construction, foundation, garage floor, or elsewhere, proper maintenance is a must-have. Without taking care of your home’s concrete, you could potentially end up with cracks. Concrete crack repair services are available if you’ve already noticed some damage in your home or are looking to make home repairs in addition to your concrete. Here are just a few common signs that it might be time to call a professional about concrete crack repair services.

Cracks In Structural Areas

Not all concrete damage and cracks are created equal. While cracks in concrete anywhere can be a problem, the ones to ultimately prioritize are the cracks that could impact structural integrity. Due to concrete’s excellent durability and performance, polished concrete flooring has quickly become a popular alternative to marble, granite, tile and linoleum for many commercial facilities. Cracks in flooring can be serious, but cracks in a foundation or load-bearing wall are issues to address as soon as possible.

Signs Of Water Damage

Depending on the location of the concrete damage, it’s possible that it could be allowing water into your home or place of business. A little bit of water might not necessarily seem like an issue, but water damage can quickly become serious and damage the structure of your home or workplace. If you can trace signs of water damage back to cracks in concrete, call for concrete crack repair services as soon as you’re able.

Preventive Maintenance

Sometimes you might come across a crack in concrete that doesn’t seem terribly serious at the moment. Maybe it’s a small hairline crack in your garage’s floor, or you remember a particular issue that caused the damage. Even if the crack isn’t a structural issue or causing more serious types of damage, it’s still important to get it taken care of quickly. Fixing a crack in concrete sooner can help avoid more expensive damage later on.
