Frequently Asked Questions
How much does a concrete installation cost?
Concrete installation costs vary depending on the size, type, purpose, site conditions, and accessibility of the project. A driveway, patio, decorative concrete project, sidewalk, commercial installation, or city project can each have very different requirements and costs.
Access to the property can also affect pricing—for example, projects requiring hand demolition or manual labor due to limited equipment access may cost more than projects where machinery can be used.
Since no two projects are exactly alike, we provide custom estimates based on the specific scope and conditions of each job. Contact us to discuss your project and get a personalized estimate.
How thick should a concrete slab be?
There isn't one thickness that works for every concrete installation. The appropriate thickness depends on what the slab will support, soil conditions, base preparation, reinforcement, drainage, and applicable plans/codes.
Application | Common starting point | Key considerations
Patios | 4 in. | Base preparation, drainage, reinforcement, finish
Walkways/sidewalks| 4 in. | Pedestrian traffic, subgrade, joints; public sidewalks may have specific jurisdictional requirements
Residential driveways | 4–6 in. | Vehicle loads, soil/base, reinforcement, edges, drainage
Garage floors | 4–6 in. |Vehicle loads, subgrade, moisture, reinforcement, joints
Heavy-duty/commercial slabs | 6 in.+ | Engineering, loading, soil conditions, reinforcement, joint design
Foundations
Project-specific
Structural plans, soil conditions, loads, footings, reinforcement and local requirements
Patios and walkways
For a typical residential patio or pedestrian walkway, 4 inches is a common starting point.
That doesn't mean thickness alone determines whether the concrete performs well. Proper excavation, a stable compacted base, drainage, reinforcement where appropriate, control joints and proper curing are all important.
For public sidewalks, we don't automatically apply the residential 4-inch rule. The applicable city or county standard can specify different requirements depending on the location and type of improvement.
Driveways
A residential driveway commonly starts around 4 inches, but 5–6 inches or more may be appropriate depending on expected loads and site conditions.
A driveway regularly used by heavier trucks, RVs or commercial vehicles should not simply be designed using the same assumptions as a passenger-car driveway.
The contractor should evaluate:
Soil/subgrade conditions
Base thickness and compaction
Vehicle loading
Reinforcement
Drainage
Joint layout
Edge conditions
Concrete specifications
Garage floors
A typical residential garage floor is often 4 inches, but the actual design depends on the expected loads and site conditions.
For example, a garage intended to accommodate unusually heavy vehicles, or equipment may require a different design.
Foundations and heavier loads
This is where the simple "4-inch slab" rule stops being useful.
Foundations, footings, structural slabs, and heavy-duty commercial concrete should be designed for the specific project. Thickness, reinforcement, and dimensions can depend on structural loads, soil/geotechnical conditions, building plans, and applicable building codes.
How long does concrete take to cure?
Concrete could take up to 35 days to fully cure. We recommend at least 24 hours before walking on fresh concrete and at least 7 days before moderate weight bearing (such as car driving/parking, patio furniture or large pot placement, etc.), a full 28-35 days is required for heavy load bearing on footings/foundations and/or over 2-ton weight on new driveways.
Can concrete be poured over existing concrete?
In some situations, new concrete can be installed over an existing concrete slab, but this is typically considered an overlay or resurfacing application and is not a service we offer.
Whether an existing slab can support a new layer of concrete depends on its condition, including cracking, settlement, drainage, structural integrity, and the condition of the underlying base. Proper preparation is also important to ensure the new material bonds properly and performs as intended.
So, when is demolition the better choice?
If the existing concrete is significantly cracked, settled, deteriorated, or structurally compromised, removing the old concrete and preparing the base before installing new concrete is often the more appropriate approach. In these situations, starting with a clean, properly prepared surface allows the new installation to be built on a more reliable foundation.
Our company specializes in new concrete installation and replacement projects rather than concrete overlays, resurfacing, or repairs. If your existing concrete needs to be removed and replaced, we can evaluate the project and provide an estimate based on the site conditions and scope of work.
What is the best type of concrete for a driveway, patio, or walkway?
The best concrete for a driveway, patio, or walkway depends on the intended use, expected traffic, site conditions, and desired appearance. Rather than using the same mix for every project, we select the appropriate concrete specifications based on the needs of each installation.
Standard vs. high-strength concrete:
Standard concrete is commonly suitable for many residential patios, walkways, and other general-use applications. Higher-strength mixes may be appropriate for driveways, commercial projects, areas exposed to heavier traffic, or applications with specific structural requirements.
Reinforcement:
Depending on the project, concrete may be reinforced with rebar, wire reinforcement, or other reinforcement systems. Reinforcement can help manage cracking and provide additional structural support when properly designed and installed. The appropriate reinforcement depends on the application and site conditions.
Finishes:
Concrete can be finished in a variety of ways to achieve the desired appearance and level of traction. Options may include broom finishes, smooth finishes, exposed aggregate, stamped or decorative finishes, depending on the project.
Additives and other considerations:
Concrete mixes can also be customized with admixtures and other additives when specific performance or installation requirements call for them. Factors such as weather, placement conditions, curing, drainage, and the underlying base are also important to the long-term performance of a concrete installation.
Ultimately, there isn't a single concrete mix that is best for every driveway, patio, or walkway. Choosing the right mix, reinforcement, finish, and installation method for the specific project is key to achieving a durable and attractive result.
How do you prevent concrete from cracking?
While concrete cracking cannot be completely prevented, proper installation can significantly reduce the risk and help ensure long-term performance.
Proper base preparation: A stable, properly graded, and compacted base helps minimize settlement and movement beneath the concrete.
Reinforcement: Depending on the project, rebar, wire reinforcement, or other reinforcement systems can provide additional structural support and help control cracking.
Control joints: Concrete naturally shrinks as it cures. Control joints create planned locations for shrinkage-related cracking, helping keep cracks more predictable.
Drainage and curing: Proper drainage helps prevent water from collecting beneath the slab, while proper curing helps the concrete develop strength and reduces excessive shrinkage.
Proper base preparation, reinforcement, control joints, drainage, and curing all play an important role in creating a durable concrete installation.
What is the difference between stamped, brushed, broom-finished, and smooth concrete?
The right concrete finish depends on the appearance, slip resistance, maintenance, and budget of your project.
Stamped concrete: Creates patterns and textures that can resemble stone, brick, tile, and other materials. It provides a highly decorative appearance but typically requires more labor and maintenance, making it a higher-cost option.
Broom-finished concrete: A broom is pulled across the freshly finished surface to create consistent, visible lines or texture. This is a popular outdoor finish because it provides good traction and is generally an economical, low-maintenance option.
Brushed concrete: Uses a brush or similar finishing technique to create a lighter or more subtle surface texture than a traditional broom finish. The exact appearance can vary depending on the brush and finishing technique. Like broom-finished concrete, it can provide additional traction for outdoor surfaces.
Smooth concrete: Provides a clean, uniform surface with minimal texture. It is easy to clean and has a modern appearance, but it can be more slippery when wet and may not be ideal for every outdoor application.
Cost and maintenance: Broom and brushed finishes are generally more economical and easier to maintain than decorative stamped finishes. Smooth finishes are also relatively simple to maintain, while stamped concrete may require additional care to preserve its appearance.
The best finish depends on the look you want, where the concrete will be installed, the amount of traction needed, and your budget.
When is the best time/weather to pour concrete?
The best conditions for pouring concrete are moderate temperatures, dry weather, and stable conditions that allow the concrete to be properly placed, finished, and cured.
Temperature: Extreme heat or cold can affect how concrete sets and cures. Hot weather can cause concrete to dry too quickly, while cold temperatures can slow curing and affect strength development. We monitor conditions and adjust our installation process as needed.
Rain: We do not pour concrete when rain is predicted within 24–48+ hours (depending on amount of rain predicted) of the scheduled pour. Rain during the early stages can wash out the surface finish, add excess water, and potentially compromise the concrete's integrity and appearance.
Hot or cold weather: Concrete can be installed in a range of temperatures, but extreme conditions may require additional precautions. When necessary, we use appropriate concrete additives and admixtures to help manage setting and curing in extreme weather conditions while maintaining the concrete's integrity and performance.
Curing conditions: Proper curing is essential for concrete to develop its intended strength and durability. Stable temperatures, appropriate moisture, and protection from extreme weather during the curing period all contribute to a successful installation.
We carefully monitor weather forecasts and site conditions when scheduling concrete pours to help ensure the best possible results.
How do I repair cracked, spalling, or uneven concrete?
The right solution depends on the condition of the existing concrete and the extent of the damage. Common options include:
Crack repair: Minor cracks may sometimes be repaired or sealed to prevent further water intrusion and deterioration.
Resurfacing: A new surface can sometimes be applied over existing concrete when the underlying slab is structurally sound.
Leveling: Uneven or settled concrete may be corrected through leveling methods, depending on the cause and condition of the slab.
Full replacement: When concrete is severely cracked, spalling, settled, or structurally compromised, removing the existing concrete and installing a new slab may be the most appropriate solution.
Our company specializes in concrete installation and full concrete replacement. We do not offer concrete crack repair, resurfacing, or leveling services. If your existing concrete requires replacement, we can evaluate the project and provide an estimate based on the condition of the site and the scope of work.
How much concrete do I need for my project?
Concrete is typically measured in cubic yards, based on the length, width, and thickness of the project area. The exact amount depends on the size, shape, and site conditions. We can help determine how much concrete your project requires and provide an accurate estimate.
How thick should my concrete be?
Concrete thickness depends on the type and intended use of the project. As a general guideline, walkways and patios are commonly around 4 inches, while driveways, garage floors, and other areas carrying heavier loads may require 4–6 inches or more. We determine the appropriate thickness and reinforcement based on your project's specific needs.
How long will a concrete installation take?
Most residential concrete projects can take approximately 1–3 days for preparation, pouring, and finishing, depending on the size and complexity of the job. Preparation may include demolition and base work, followed by pouring and finishing. Concrete then requires time to cure, with full strength typically developing over approximately 28 days. Weather and site conditions can affect the timeline.
How do I choose a good concrete contractor?
Choosing the right concrete contractor starts with finding someone you can trust and feel comfortable working with. Look for a contractor who is properly licensed and insured, experienced, and happy to provide references or examples of previous work. A clear estimate should explain the scope of work, materials, preparation, finish, timeline, payment terms, and warranty.
Most importantly, choose a contractor who takes the time to answer your questions, communicate clearly, and make sure you understand what you're getting before work begins.
