Frequently Asked Questions

How long before I can drive on new concrete?

• You can typically walk on your concrete within 24 hours.
• Vehicles should stay off for at least 72 hours.

For heavier vehicles or commercial applications, we may recommend additional curing time to maximize strength and longevity.

Will my concrete crack?

• Concrete is a natural material and may develop cracks over time.
• We install proper control joints and saw cuts to guide cracking where it should occur. With proper base preparation, reinforcement, and finishing practices, we minimize random cracking and maximize performance.
• Quality installation makes the difference.

What affects the cost of a concrete project?

Every project is different. Pricing depends on:

• Thickness of the slab
• Site access and grading conditions
• Reinforcement (rebar or wire mesh)
• Base preparation requirements
• Permits and inspections
• Decorative or specialty finishes

We provide detailed estimates so you understand exactly what goes into your project — no surprises.

Do you work on commercial projects and larger developments?

Absolutely. Commercial concrete is our primary focus.

We have extensive experience with:

• Multifamily developments
• Retail centers
• Light industrial projects
• Site flatwork and paving

We understand schedules, site coordination, and the expectations of general contractors and developers.

Do you offer a warranty on your work?

• Yes. We stand behind our workmanship.
• We provide a one-year workmanship warranty on our concrete installations. This covers defects related to installation.
• It’s important to note that concrete is a natural material and may experience minor surface cracking or color variation over time — which is normal and not considered a defect.
• Our goal is long-term performance, and we take pride in doing the job right the first time.

Are you licensed and insured?

• Yes. Guizar Concrete Construction is fully licensed and insured.
• We carry general liability insurance and operate with trained, experienced crews who understand industry standards.
• Whether it’s a residential driveway or a large commercial development, you can feel confident knowing your project is handled professionally.

How thick will my driveway or patio be?

Most residential driveways and patios are poured at 4 inches thick, which is industry standard. However, we evaluate every project individually. If heavy vehicles, RVs, or commercial use are expected, we may recommend thicker concrete and added reinforcement to ensure long-term durability.

We build concrete to perform — not just to pass inspection.

Do you remove and replace existing concrete?

Yes. We handle full demolition and replacement projects. Our team has the equipment and experience to remove old concrete safely and prepare a proper base before pouring new material — which is critical for long-term durability.

How far out are you typically scheduling?

We are typically scheduled 1–2 weeks out, depending on project size and season. Larger commercial projects may require additional planning time, especially if coordination with other trades is involved.

Do you handle right-of-way sidewalks and city work?

Yes. We regularly complete city sidewalks, curb & gutter, ADA ramps, and right-of-way concrete work. We are familiar with municipal standards and inspection processes, which ensures work is done correctly the first time.

What’s the practical difference between residential and commercial concrete work?

Load requirements, slab thickness, finishing tolerances, and coordination complexity are all higher on commercial work. A warehouse floor has different reinforcement design, joint spacing, and flatness requirements than a residential driveway. Our experience across both means we understand what concrete needs to do in different applications — and we’re not applying residential habits to commercial jobs or vice versa.

Do you work from engineering or architectural plans?

Yes. For commercial and municipal projects, working from plans and spec packages is standard for us. If there are questions about spec or scope during our review, we raise them before bidding. We can also coordinate directly with structural engineers or project architects during construction when RFIs come up.

Do you handle permitting on commercial projects?

Yes. We handle permitting where it’s required and coordinate inspections as part of the project scope. For commercial work in the Denver metro, that typically means permit applications through the city or county, coordination with the building or public works department, and scheduling inspections at the appropriate stages. That’s built into how we manage jobs, not something we leave to the GC to sort out.

Do you handle demolition and removal of existing concrete?

Yes. Demo and haul-off of existing concrete is part of most replacement scopes. We include that in the estimate upfront. If there’s existing slab that needs to come out before new concrete goes in, that work gets priced in from the start.

Why does concrete work in Denver require more preparation than other parts of the country?

Most of the Denver metro sits on expansive clay soils. The ground moves — it swells when it’s wet and contracts during dry stretches, which is exactly what Colorado’s climate delivers in cycles. If the subbase isn’t compacted correctly and graded to direct water away from the slab, you’ll get settling and cracking regardless of how clean the surface pour looked on day one. A lot of residential concrete work in the Denver metro is done by crews who cut prep time because the homeowner can’t see it. The prep is the job — and skipping it shows up two to five years later.

How do Colorado’s freeze-thaw cycles affect concrete?

Ground temperatures in the Denver metro cycle above and below freezing repeatedly through a typical winter. Moisture that migrates under a slab freezes, expands, and puts upward pressure on the concrete from below. At the surface, exterior slabs need to be air-entrained — that’s a mix design requirement that gives the concrete microscopic air pockets to absorb freeze-thaw stress without scaling or spalling. A well-poured slab can still fail early if the base work wasn’t done correctly, and a slab without proper air entrainment will show surface damage faster than it should. We account for both as a baseline on every outdoor project, not as an upgrade.
