Is concrete the same as cement?
Although the terms cement and concrete are often used interchangeably, cement is actually just one of the many ingredients that make up concrete. The mixture for concrete includes a combination of materials such as crushed stone, sand, or gravel, which are then mixed with cement and water. Essentially, cement is a component of the overall structure of concrete.
In terms of quality, concrete can be compared to mortar. However, due to the addition of mixed aggregates, concrete is stronger and more durable than mortar. Furthermore, concrete has a thinner consistency and a lower cement-to-water ratio than mortar.

Do I really need to hire a concrete contractor?
While there are numerous online tutorials available to teach you how to lay concrete, it's important to note that building a long-lasting structure necessitates expertise and proficiency that can only be acquired through years of experience in the field. Additionally, you'll have to buy specialized equipment and tools for laying concrete. It's crucial to be knowledgeable about the removal of concrete, the preparation of the subgrade, and the pouring of the cement mixture. Otherwise, you may have to spend more money on redoing errors and repairing damages. By hiring a skilled concrete technician, you can ensure that the job is done to the highest standards.
How long does it take for concrete to dry in construction?
In the context of concrete, the term "cure" is used instead of "dry." Curing involves maintaining an optimal level of moisture in the material to achieve the desired result of hardening, which can be achieved through either a chemical reaction or physical process. Once the curing process is complete, the result is a solid and durable surface that can withstand wear and tear.
Typically, it takes around 28 days for concrete to fully cure. However, within the first 24 to 48 hours of pouring, the surface will have already set and become solid enough to walk on. It's important to note that the curing conditions also play a crucial role in determining the strength and durability of the concrete slab.
When can I use my new concrete surface?
As mentioned, the maximum curing time for concrete is 28 days. Nevertheless, it's possible to walk on the surface within 24 to 48 hours after pouring. However, if you intend to drive on the surface, it's advisable to wait for at least seven days before using it. For larger vehicles such as trucks and SUVs, it's recommended to allow the concrete to fully cure. Wait for a minimum of 30 days before parking or driving on it. If multiple individuals will be utilizing the concrete driveway, it's recommended to place warning tape around the area and notify others to avoid the perimeter while the concrete cures.
How long will the concrete surface last?
Concrete is renowned for its long-lasting properties, making it one of the most cost-effective material choices available. Its durability is among the highest, with a general lifespan of approximately 50 years, provided the surface is properly maintained. However, the strength and durability of the concrete will depend on its quality, which is why it's essential to only work with qualified concrete contractors. Our skilled technicians utilize tried-and-true methods and the latest techniques in concrete laying to ensure that our clients are left with results that will endure for many years to come.
Will the concrete chip or crack?
Despite our efforts to create extremely durable concrete structures, cracking may still occur on the surface. It's important to note that concrete is a rigid material and lacks the flexibility and free movement of asphalt or pavers. Water is a key component of the poured concrete mixture, and as it evaporates during the drying and curing process, the concrete will shrink. This shrinking phase can lead to the formation of cracks in the newly poured concrete, with some surfaces cracking as early as 24 hours after pouring due to material settlement. However, to enhance surface density and protect against such cracking, we apply a penetrating sealer.
How do I prevent chipping or cracking?
When we describe concrete as durable, we are referring to the structural integrity of the material. However, it's nearly impossible to create a concrete slab that is entirely resistant to chipping and cracking. Even the most well-designed building foundations and bridge decks will experience weathering and damage over time. Cosmetic damages do not indicate project failure. To minimize the severity of settlement cracks and shrinkage, our team can implement necessary reinforcement measures by incorporating steel wires or steel rebars within the project to provide an additional level of structural support.
Can you work around my sprinklers?
We have completed numerous jobs involving sprinkler systems. Typically, we position the sprinkler heads in strategic locations near or directly adjacent to existing concrete to ensure adequate watering of all grassy areas. This design makes sense for the functionality of the sprinkler system, but it also puts the heads at risk of damage during the concrete removal process. If such damage does occur, we take measures to salvage the broken pieces and set them aside for future repair by a sprinkler contractor. It's important to note that the repair costs are not included in our quotation.
Should I seal my new concrete often?
One of the most critical inquiries to make regarding your new concrete concerns maintenance. Our skilled and experienced technicians are dedicated to constructing highly durable and long-lasting structures. However, to preserve the concrete's integrity, regular resealing is necessary. For high-traffic areas such as driveways and walkways, we recommend resealing the surface at least once a year, preferably during the fall season. For patios and other low-traffic areas, this maintenance routine can be performed every other year. With proper care, your concrete structures can remain in excellent condition for many decades.
What kind of sealers can I buy?
Contractors from the same geographic location may have differing opinions on which sealer is most effective. In recent years, several federal laws have been revised to enhance air quality and safeguard the surrounding atmosphere. As a result, manufacturers have been mandated to restrict the types of chemicals they use in their products, particularly concrete sealers. High-gloss sealers from the past are not beneficial for the environment or you. Although they may initially produce a shiny surface, this effect is short-lived. Instead, we advocate for the use of water-based, environmentally friendly concrete sealers, which provide outstanding protection.
