Concrete Crack Hazard Removal

Do you have concrete on your property? Would you like to prevent it from cracking? One of the most common complaints business owners have is that their concrete is starting to crack. They may think that the initial contract or may not have done a very good job; however, concrete is like everything else on your property. You need to take care of it if you would like it to last. How can you prevent concrete from cracking? What should you do if you notice that your concrete is starting to crack? There are several important points to consider.

Why Does Concrete Crack?

There are several reasons why concrete might be cracking. Some of the most common reasons include:

  • There might be too much water in the concrete mixture. Concrete does not require a lot of water in order to achieve its maximum strength. Excess water can reduce the strength of the concrete, leading to shrinkage. As concrete begins to harden, it shrinks. This is because excess water is evaporating. Excess water leads to more shrinkage, literally pulling the slab apart.
  • The concrete might be drying too quickly. If concrete is drying too quickly, it might not be cured properly. It is important to reach out to a professional contractor to make sure the concrete is not drying too fast.
  • There might not be any control joints in the concrete. Control joints are put in place to help the concrete crack where it should. If there aren’t any control joints, the concrete might end up cracking.

These are just a few of the many reasons why concrete might crack.

How Can You Prevent Concrete from Cracking?

There are several ways to prevent concrete from cracking. Some of the top methods include:

  • Install control joints. This will prevent the concrete from cracking in vulnerable places.
  • Always cure the concrete properly. If the concrete does not cure properly, it may begin to crack.
  • Check the water to cement ratio again. The water to cement might need to be reduced to prevent excess shrinkage.

In order to properly address this issue, you may need to reach out to a trained contractor.

What Should You Do if You Notice Concrete Cracks?

If you noticed that your concrete is beginning to crack, the first thing you should do is mark the concrete hazards. That way, people do not enter the area unknowingly, which can prevent serious injuries and accidents from taking place. Concrete crack hazards are dangerous and should be treated as such.

If you can do so safely, take a close look at the crack. Try to remove any debris that might be present. You may need to use a wire brush in order to appropriately clean the crack. You may also want to use a pressure washer if you know how to use one safely.

If you are familiar with concrete, you may be tempted to fill the crack yourself. Even though you might be able to temporarily patch it, you should rely on a trained professional for a permanent repair job.

Reach Out to Trained Professionals for Help with Concrete Cracks

Do everything you can to prevent concrete from cracking. If you work with an experienced professional, you should be able to get as much life as possible out of your concrete. If you notice cracks in your concrete, reach out to a trained professional for assistance. That way, you know the repair job is completed appropriately the first time around.

How To Build Concrete Steps & Add Value To Your Home

If you are reasonably handy with power tools and understand the importance of getting a project level and square, building concrete steps can save you a few dollars. As DIY tasks go, concrete steps can be somewhat labor-intensive. But with the right tools and by following these steps carefully, you can add value to your property.

1: Gather Your Tools & Materials

You will likely need the following tools and materials to complete a set of concrete steps: a 4-foot level, framing square, circular saw, hammer, wheelbarrow, shovel, concrete edger, broom, tape measure, circular saw, concrete, trowel, 2x lumber, gravel, rubble, and plywood.

2: Take Initial Measurements

Measure the height from the ground to the bottom of the doorway. Now calculate how many steps you will need extending away from the building at 7 inches per step. This is to say, each step is supposed to be no more than 7 inches. If the door threshold’s bottom is 21 inches from the ground, you usually need three concrete steps. If the height can’t be divided by 7 inches evenly, get each step as close as you can. You can make shorter steps, but not taller ones.

3: Set Your Footings

Excavate the ground where the concrete steps will be poured. Layout 2x lumber to form two boxes to pour the footings. Check that they are perfectly level. These should extend about three inches wider than your steps. As the concrete starts to harden, insert rebar into the footings so that it sticks up about 6-8 inches. Fill the center space with gravel.

4: Build A Frame

Measure and cut two plywood sections to mirror the sides of the concrete steps, based on your measurements. Set one on each footing with 3 inches protruding at the bottom. Check that they are also level. Cut 2x materials to create the face of each step, not the part you would walk on. Hammer them in place. Cut a 2×4 to create a brace. This typically is one length that extends from the ground and over the steps. Attach shorter braces — called cleats — that point down and support each step o the front. Hammer the last cleat into the ground and attach the long length to ensure it stays in place. Check to make certain your concrete steps will all be level, and the form is square.

5: Fill In The Form

Consider using stones, bricks, or cinderblock pieces to fill up a portion of the form. This will cut down on the amount of concrete needed. This strategy also tends to alleviate some pressure on your forms when the concrete is poured. Save room to insert lengths of ½-inch thick rebar about 3-4 inches below the concrete steps’ surface.

6: Fill With Concrete

Mix your concrete in the wheelbarrow and shovel it into the concrete steps form. It’s essential to prepare a firm but moist concrete mixture. This will help prevent leakage, reduce the hardening time, and allow you to manipulate it effectively.

7: Detail Your Concrete Steps

Use the edger to enhance the outer areas’ appearance once the concrete is fairly hard. Then take the broom and add traction lines to the spaces people will place their feet.

8: Remove Forms

Concrete steps usually take 12 to 24 hours to cure. Once the concrete has hardened, remove the forms. A flat tool such as a trowel may prove effective. Keep in mind that hard impacts or prying from tools such as a crowbar can damage the steps.

Concrete steps require some muscle to build. While handy homeowners can save a few bucks on labor, a masonry contractor may be worth considering.

The History of Concrete: An Overview and How It Is Used Today

Today, one of the most ubiquitous materials as concrete. Many people see concrete on their driveway, and utility buildings, and in numerous other locations. Concrete is popular because it is an expensive, durable, and versatile. At the same time, many people might be wondering where concrete came from. When it comes to the history of concrete, there are a few key points to keep in mind.

Early Concrete Predecessors: Limestone

The history of concrete can be traced back to ancient times. There were numerous ancient materials that were used by early civilizations. These ancient materials formed the foundation of concrete as we know it today. For example, one of the most common materials that is used to make concrete is limestone. When sand and water were added to Limestone, it became a plaster type material that was used to help stones adhere to one another. As a result, these materials were improved. Over time, modern concrete came into existence following these procedures and limestone is an important ingredient in modern concrete.

The Evolution of Cement into Concrete: A Key Part of Concrete History

Another important element that goes into modern concrete is cement. Cement has been around for an extended period of time. Nearly 12 million years ago in the Middle East, natural deposits were formed when an oil shale and Limestone combusted spontaneously, leading to cement. Keep in mind that cement and concrete are not the same things. Concrete is a composite building material that is made out of cement along with numerous other ingredients. At the same time, cement was used thousands of years ago and still plays a key role in concrete today.

Concrete History: Its First Uses in Human Civilization

The first uses of concrete can be traced back to ancient traders in the Middle East. These traders occupied and controlled numerous oases that eventually became a small empire. Eventually, these traders discovered the advantages of using hydraulic lime. This is cement that gradually hardens underwater. Eventually, they learn how to build kilns to supply mortar that was used for the construction of rubble houses. This is where the first concrete floors were discovered. These ancient peoples understood that in order to keep the concrete functional, they needed to keep it dry. Excess water leads to voids and weaknesses in the concrete. The building practices that they discovered form the foundations of making modern concrete today.

Concrete Has a Number of Uses Today

The practices that were used by the ancient peoples formed the foundation of how modern concrete is used today. Today, despite all of our technological advances, we still rely on concrete. Concrete can be found in the floors of utility rooms, in driveways, and in numerous other places. Furthermore, it is even possible to seal concrete to prevent liquid from damaging it. In this manner, concrete is still one of the most useful materials today. Those who are looking to get the most out of their concrete should make sure that they rely on an experienced company that can guide the way. By trusting an expert concrete company that understands how concrete history influences its uses today, everyone can rest easy knowing that they are going to get the most out of their concrete investment.

How to Maintain Concrete: Everything You Need to Know

For centuries, concrete has been the prime choice building material for all sorts of projects, including sidewalks, parking lots, bridges, and roads, among others. This widely used building material is basically a highly refined mixture of coarse aggregate and meticulously formulated additives that enhance strength and durability. Nevertheless, that doesn’t necessarily mean that concrete is maintenance-free. The following are some helpful tips on how you can achieve concrete minatenance in the sidewalks and parking lot:

1. Clean concrete surfaces annually

The commonest stains that you’ll find on your concrete parking lot are grease, oil, and anti-freeze stains. These stains are usually caused by radiator fluid and oil drizzling from the cars that drive into your facility on a daily basis. Anything from automotive leaks to birds’ droppings and fallen leaves can ruin the aesthetic appeal of your concrete parking lot.

For a business that caters to a discerning clientele, it is imperative that the stains be washed out from time to time. The Florida Concrete & Products Association recommends that stains on concrete surfaces be cleaned off at least once per year. An annual cleaning will not only rejuvenate your facility’s appearance, but it will also extend the life of the top layer.

2. Seal concrete joints annually

Concrete joints, also known as control/contraction/expansion joints, are usually placed in concrete slabs to prevent random cracking when concrete shrinks or expands due to changes in temperature. To ensure that the joints keep your parking lot structurally sound, they have to be sealed.

Most experts recommend that concrete joints be sealed at least once per year. This can help to keep fluids, water and debris from infiltrating and damaging the sub layers of your concrete sidewalks or parking lot. Ensure that the sealer used for joint sealing allows vapor to escape from within the concrete.

3. Repair cracks and potholes Instantly

Even when you keep up with annual cleaning and joint sealing, some cracking is inevitable in due course. Age and regular use will ultimately wear down concrete, letting grime and water inside. The more debris and moisture, the flimsier the concrete sidewalks or parking lot will become, leading to more cracking and deeper potholes.

Besides being aesthetically unappealing, big cracks and potholes can also affect the performance and reduce the lifespan of your concrete. It’s therefore advisable that you have concrete repairs and resurfacing done as soon as you notice signs of wear and tear. You can also have a paving contractor perform structural inspections periodically to determine the condition of the structural elements. Doing so will enable you to know whether your concrete surfaces need repair or repaving.

4. Repaint concrete periodically

After some years, the striping in your parking lot will wear away and make traffic markings and spot divisions hard to see. Repainting the stripping will make the traffic patterns visible for both pedestrian and drivers. This will not only ensure that everyone that visits your property gets to move safely, but it will also give your sidewalks or parking lot a fresh look. In fact, repainting your concrete is the simplest and inexpensive way to add the wow factor to your business premises.

When you are a business owner, your parking is an extension of your business. Therefore, its state will say a lot about your business. Keeping your parking lot and the sidewalks in good shape will not only boost the curb appeal of your facility, but it will also enhance safety for pedestrians and vehicles traveling across it.

Hot Weather Concreting: How to Avoid the Problems that it Presents

The Perils of Concreting During
Hot Weather And How To Avoid Them

Hot weather concrete pouring can cause a myriad of problems. Many people think it is just about the heat itself but there is more to it than that. Many factors affect the quality and success of concreting during hot weather conditions. Hot weather, as defined by ACI 305R is any combination of the following:

  • High ambient temperature above 90 degrees
  • High concrete temperature
  • Low relative humidity
  • High wind speed
  • Solar radiation

The heat is not the problem as concrete cures through hydration and not temperature. However, when the concrete becomes hotter than 77 degrees, it speeds up the hydration timing. If the concrete isn’t hydrated properly, it will be weak, crack easily and be more susceptible to damage from freezing and thawing. Construction crews must prepare for hot weather concrete placement.

Ways to Prepare for Pouring Concrete in “Hot Weather”

  • Crews should avoid pouring the concrete during the hottest part of the day. Tracking hour by hour temps can assist with this determination. It is also wise to avoid extreme temperature changes. Pouring concrete on a hot day when followed by a cool night can cause thermal cracking to ensue.
  • A team of workers should be available to ensure that the work is finished quickly and efficiently. Truck delivery should occur early in the day and a group of laborers ready to start immediately. Check for any potential delays so that the task will be completed in a timely manner.
  • Sunshades, windbreaks or mist fogging can be used to protect and slow down the process of the concrete curing too quickly.
  • Extended set additive, moderate heat cement and blended cements can provide solutions to pouring concrete in difficult conditions.
  • Keeping concrete in the shade before pouring or using an evaporative retarder may help as well.
  • Once the water is added to the mix, reduce the mixing time.
  • Ice or cold water can be added to the mixture to cool down the concrete. Cold water can reduce the heat of the concrete by about 10 degrees and ice by approximately 20 degrees.
  • If a slab is being poured, putting cool water on the sub-grade is another neat trick.
  • Control-joints can be spaced closer together to aid in strengthening.
  • Steel Fiber Concrete can be used to make slabs to add after walls and roofs are built out. Adding steel fiber to concrete has advantages and disadvantages so do your homework before choosing this method.
  • Extreme weather conditions may require the infusion of liquid nitrogen into the mixers. This solution can be costly as there are concerns about damage to blades and precautions must be taken.
  • There are several curing methods that can be used. Understanding these methods directly impacts how successful your curing process is.  Concrete companies will want to have a plan ahead of time as to the correct method for each individual situation and to follow through with recommended procedures.

Setting concrete in difficult situations is a complicated process. However, with a little research and a lot of preparation, a concrete job can have favorable results.
