DIY Mold Removal Guide for Concrete Pavements

Water stops and other moisture barriers are commonly installed beneath concrete foundations; however, these can wear out and deteriorate over time. They can also become defective or break under extreme conditions. In the case that water and moisture get into the foundation of concrete walls or floors, there is a chance that both mildew and fungal growth can occur. No one wants mold growth anywhere on their properties, so when it becomes apparent, immediate action is required. Stopping mold growth in its tracks can greatly reduce the need for costly repairs, restorations, and reconstruction.

Mold Removal Process for Concrete Surfaces

The process of cleaning mold off of concrete is fairly straight-forward and therefore easy; however, it does require some initial grunt work. Be prepared to sweat a little when it’s time to scrub mold and mildew out of concrete. It doesn’t require a lot of tools either; simply locate a hard-bristled scrubbing brush, household bleach, clean water, and protective cleaning gloves. Combine the bleach and cold water (1 part bleach to 4 parts water) and liberally apply the solution to the affected area. Once the area is saturated, use the scrubbing brush to powerfully brush and rub out the mold from the concrete.

Once you have finished scrubbing in this solution, allow it to set it for a few hours; longer if the mold is extensive. Finish with a thorough rinse using fresh clean water. Use room-temperature or cold water so to not promote future mold growth. Heat, moisture, and shade is all it takes for mold and fungus to form. It is best to use a power washer to rinse the bleach solution away because the pressure of the water works well to thoroughly rinse away the remaining particles.

For Very Serious Mold-Damaged Pavements

If you prefer to not handle bleach or concoct your own solution, you can choose to purchase a store-brand mold-killing detergent. Although store-bought, they provide the same results and require the same steps. For severe cases of mold, it is best to outsource professional concrete repair or replacement services. If you want great pavements all year long, be sure you choose a certified pro to install, repair, and protect your concrete.

Concrete Paving

Many questions start to arise once a contractor or customer notices cracks and crevices in their newly paved concrete foundation. They wonder if the concrete technician added too much water to the mix; or if the sand content was too high. Was fiber or wire mesh installed? Were the saw cuts placed correctly?  Although it is easy to blame the contractor that installed the concrete, they are not always the root of the problem.  There are natural circumstances beyond our control that can cause pavement to crack. Surprisingly, the main culprits behind self-destructing pavements have to do with cold weather and hot weather.

Freezing Temperatures

In the northern parts of the nation, freeze and thaw cycles are the most common reasons behind cracked concrete pavement. This cycle begins when water inside the ground freezes from cold temperatures; and when water freezes it turns into ice and expands. This increase in mass can cause the ground to rise or shift, causing anything above it to do the same. If concrete pavement lies above a frozen and lifted ground, the concrete is likely to be implicated as well.

When seasons change and the ice melts, pavements are shifted and moved again because there is a void where solid ice once existed. This results in more cracking and damage. There is not much a property owner can do to prevent natural occurrences like this; however, in order to prevent a freeze thaw cycle issue, wait until spring and summer to install new concrete. This way it has time to strengthen and solidify before harsh weather can cause its deterioration.

Extreme Heat

In contrast to freezing temperatures, concrete can also crack in extreme heat. In the south and coastal regions of the United States, it is common for pavement to rupture from extended sun exposure and heat. Just as ice expands within the ground, heat causes concrete to expand and move as if it were baking in the sun. Once the sun or temperatures go down, the concrete retreats back to its normal state. This consistent expansion and decreasing in size can make pavement more susceptible and vulnerable to cracks, crumbling, and deep crevices.

The fact that concrete is moving and shifting is the damaging factor; not the magnitude or weight of the damage. In order to prevent natural occurrences and weather from damaging your newly paved concrete, be sure to discuss the best times to install new pavement. Always use a reputable and licensed paving company that can answer your questions about concrete installation, or concrete repair and protection, as they are the industry experts that can deliver precision concrete placement you can trust.

Causes and Cures for Concrete Cracks

Cracks in concrete are a very common occurrence, but more often than not, misjudged. In fact, the American Concrete Institute (ACI) acknowledges this issue by stating that it is unrealistic to expect crack-free concrete, and normal to expect some degree of cracking, despite the quality of product and installation. The only method of crack prevention is to use certain paving strategies to control the cracking. And although not all concrete cracks can’t be entirely controlled, all can be explained.

Continue reading to learn some common, and overlooked, causes behind concrete cracks, and some methods that professional pavers use to prevent excessive cracking in concrete.

Cracks in Concrete

A professional paving team will use special tools and strategies to stop concrete from cracking excessively. This includes proper sub-grade preparation, accurate water-to-material mix ratio, and fashioning reinforcement in the proper places. For this reason, it is vital to choose an experienced and reputable concrete repair service that can provide quality results you can trust. But keep in mind that concrete cracks can happen despite of everything else. Here are some reasons why:

Shrinkage

One of the most common reasons for cracks to appear in newly-paved concrete is plastic shrinkage. When concrete is still soft, and not yet hardened, it is in its plastic state. This is when the concrete is still full of water. And since water takes up space, it makes the concrete slab a certain size and shape. But as the concrete cures, and leaves its plastic state, the water inside begins to evaporate. This can cause the concrete to slightly shrink.

Concrete is rigid, so the shrinkage causes a lot of stress on the concrete slab. As it moves along the granular sub-grade, it can cause the slabs to move apart from each other. And when the stress gets to be too much, cracks will appear to relieve tension. All of this is exaggerated in hotter climates and weather.

When installed properly, these inevitable cracks are hairline fissures, and barely visible. But if the installation and mixing process is done inadequately, the cracks will be larger and more abundant. One example is mixing the concrete improperly by making it too wet. It is important to get the right water-to-mix ratio to ensure less cracking. It is common for under-qualified pavers to mix concrete with more water because it is easier to install and finish, especially in hot temperatures. Although a few extra gallons won’t have much effect, too much water can create weaker pavement and larger cracks.

Expansion

When concrete is exposed to hot weather, it expands as it increases in temperature. Cracking occurs when the concrete slab expands to an obstruction point that it cannot pass, such as a curb, brick wall, or even another concrete slab. Professional pavers know to use expansion joints to help control the amount of cracking in concrete. An expansion joint is simply a point of separation between two static surfaces. Also called isolation joints, these points of separation are filled with a type of compressible material that provides adequate shock absorption. This allows a little room for concrete to expand, thus reducing the amount of cracking.

Heaving

Heaving is another common cause behind concrete cracks. It occurs when concrete slabs, like sidewalks, experience a series of freeze/thaw cycles. The repetition of frozen and thawed states causes concrete to shrink and expand multiple times. This results in the ground beneath concrete to lift, causing the slab to heave or bow. Slabs can rise several inches, and also be affected by large tree roots.

Round Objects

Drains, sewer covers, and other rounded objects in concrete pavement are common causes for cracks. In the same way that concrete experiences expansion and shrinkage, round objects inhibit concrete from compressing, thus resulting in excessive stress on the slab. This creates cracks in the concrete.

Professional pavers will constructively incorporate control joints concrete slabs. These are contraction joints that give concrete a designated place to crack when shrinkage or expansion occurs. Instead of cracking randomly through the slab, the concrete will crack exactly on the control joints.

A Few Considerations Regarding the Integrity of Concrete Surfaces

When it comes to choosing between concrete resurfacing and concrete repair, there are a few important considerations to think about before making any final decisions. Choosing the proper solution for concrete renovation can save contractors and property owner’s significant amounts of money and time, and avoid potential do-overs.

Continue reading to learn the questions you should be asking yourself, and your concrete contractor, regarding concrete resurfacing and repair.

Concrete Repair or Concrete Resurfacing

Concrete is a porous, permeable pavement material, which means it can absorb moisture and water. Water enters these pores, freezing and thawing, causing cracks, fissures, crevices, crumbling, and more. Overtime, this exponential accumulation of rain water, winter precipitation, and natural wear and tear from foot and vehicular traffic, causes concrete surfaces to breakdown. In order to combat these problematic variables, it is important to use a high-quality concrete sealer.

Sealcoating is vital for additional and long-term protection against natural elements, harsh weather, changing climates, traffic, and more. Applying a seal coat to a newly paved or repaired concrete surface is safeguarding your investment. As concrete breaks down or deteriorates, property owners might begin to think about renovating or replacing their pavement. At this point, it is wise to think about certain considerations to properly assess whether or not to repair or resurface concrete pavement.

Here are some important questions to ask yourself about your commercial concrete pavements:

What is the Structural Condition of the Concrete?

Is the concrete safe to walk or drive on? Are the cracks larger than a quarter of an inch? Have the concrete slabs moved vertically yet? If the answer to all these questions is no, then a full concrete repair or replacement project is not necessary. Instead, concrete resurfacing can simply fill in the cracks and strengthen the foundation. You can even go above and beyond by adding some upgraded aesthetics to enhance and refresh the appearance of your concrete pavement.

Is the Concrete Sunken or Raised?

When concrete is sunken low into the ground, or raised above the surface level, you might still be able to avoid a full-on concrete repair project. Instead, you may have the option to use a concrete hydraulic leveler to even out the surface, and follow it with concrete resurfacing. Hydraulic concrete levelers drill a 2 to 3 inch hole in sunken concrete, and then inject a lime blend material to raise it back up to the proper level. Follow this with a polymer modified cement treatment for a professional finish.

Is More than 50% of the Concrete’s Integrity Jeopardized?

If at least fifty percent of the concrete surface is deteriorated, cracked, or sunken, concrete repair is the best option. If the thickness of the concrete is eroded or crumbled more than one and a quarter inch, then concrete repair is also the necessary choice.

For accurate industry information and advice regarding asphalt and concrete repair or installation, speak with a licensed pavement repair contractor. They can offer you the most accurate advice for choosing between concrete resurfacing and concrete repair. Be sure to choose a licensed, bonded, and insured pavement repair company with several years of experience in the industry. This will ensure you are receiving honest, educated, and accurate information.

Why Does Concrete Crack?

You would think something as hard and solid as concrete wouldn’t crack so easily. The truth is that concrete pavement is susceptible to a variety of elements and influences that can cause it to crack, buckle, crumble, and more. Although faulty concrete installation jobs can sometimes also be a reason behind crumbling or cracked concrete (i.e. no wire mesh installed, too much sand in the mix, watered-down mix, etc.), in most cases, the reasons are natural.

Cracked Concrete

Concrete commonly cracks in harsh environmental conditions. For example, concrete often cracks during freeze and thaw cycles; mostly in the northern climates of course. Freezing weather can freeze an underground water supply solid, and solid ice expands and requires more space than water. This is where the concrete is inflicted. The water-turned-ice expands underground, creating rifts and lifts in the above-ground concrete. It can cause the concrete to raise as much as two to three inches or more in most cases.

In the spring time, this cycle is reversed, causing even more concrete cracks and fractures. This is because as the ice melts in spring, causing the solid ice foundations beneath the concrete to disappear. This results in crumbling or caving concrete because there is no longer string ice beneath it for support. Once the summer time comes, even more damage is possible.

In the late spring and summer months, concrete pavement can suffer from cracking and fading from extensive sun exposure. This type of heat exposure can cause the concrete to warp and move even more so than it would in its freeze/thaw state. Once the sun goes down, the concrete will retract and settle in its original position. The problem is that the frequent instability and movement of concrete in hot weather can eventually weaken and crack the foundation altogether.
