Can You Lay Pavers Over Concrete?

Wondering if you can lay pavers over an existing concrete slab? Learn the pros, cons, and best practices for transforming your old concrete into a stylish paver patio or driveway.

If your concrete patio, driveway, or walkway is looking a little tired, you might be wondering: Can I just lay pavers over it? The good news? Yes, you can — and it's a popular solution for homeowners in Portland and beyond who want a quick upgrade without the mess of demolition.

In this post, we'll break down:

• Whether laying pavers over concrete is a good idea
• The right (and wrong) conditions for it
• Step-by-step overview
• Common mistakes to avoid
• Professional tips from our team at Xcelent Concrete Services

Why Homeowners Choose to Lay Pavers Over Concrete

Here's why many choose this route:

1. Saves Time & Money

Removing a concrete slab is labor-intensive and costly. Laying pavers over it avoids the need for demo and disposal.

2. Instant Aesthetic Upgrade

Pavers add charm, pattern, and color to what was once a plain gray surface.

3. Durability + Style

Concrete underneath provides a solid base, while pavers on top deliver beauty and slip resistance.

But First — Is Your Concrete Surface Suitable?

Before you get too excited, not every slab is a good candidate. Here's what to check:

• 1. Condition of the Concrete

  • Minor cracks? Okay.
  • Major shifting, sinking, or crumbling? Not okay. The concrete must be level and structurally sound.
• 2. Drainage

  Water should flow away from your home. Pavers won't fix existing drainage problems — in fact, they could make it worse.

• 3. Height Considerations

  Adding pavers increases height. Make sure this won't interfere with:

  • Door thresholds
  • Steps
  • Garage floors
  • Lawn grading

How to Lay Pavers Over Concrete (Step-by-Step Overview)

This is how the pros do it — and how we do it at Xcelent Concrete Services:

Step 1: Clean & Prepare the Surface

Remove any dirt, oil stains, or moss from the concrete using a pressure washer. A clean surface ensures proper adhesion and leveling.

Step 2: Install a Bonding Layer or Sand Bed

You have two main options:

A) Sand or Mortar Bed

• A thin layer of sand allows you to adjust the height of each paver.
• Optional edge restraint or mortar around the perimeter helps hold the shape.

B) Bonding Agent + Mortar

• This method "glues" the pavers directly to the concrete.
• Best for small areas like front steps or walkways.

Step 3: Lay the Pavers

Start at one corner and work your way out. Use spacers for even joints and a rubber mallet to tap pavers into place.

Step 4: Add Joint Sand or Sealant

Sweep polymeric sand into the joints. This locks the pavers in place and prevents weeds or ants from getting through.

Optional: Seal the surface for added protection and shine.

Common Mistakes to Avoid

Even though this method is quicker than a full install, it's not foolproof. Avoid these pitfalls:

Skipping Drainage Considerations

Trapped moisture can lead to mold or freeze-thaw damage.

Using Over a Bad Slab

Covering up a failing slab only hides the problem temporarily — and makes it harder to fix later.

Not Accounting for Height

Added thickness could create trip hazards or block doors.

When You Shouldn't Lay Pavers Over Concrete

There are times when starting fresh is better:

• If the concrete is crumbling or sinking — No amount of pavers will fix the foundation.
• If you want grass or gravel joints — A soil or sand base is required.
• If water already pools in areas — Fix the drainage first.

Frequently Asked Questions (FAQ)

Do I need to use adhesive?

Only if you're mortaring each paver down. For patios or driveways, a sand bed with edge restraints is usually sufficient.

Can I lay pavers over a concrete driveway?

Yes — but only if the concrete is in great condition and drainage is addressed. Driveways need edge restraints and heavier-duty pavers.

Will the pavers shift or move?

Not if they're installed correctly with edge restraints and proper base preparation.

Conclusion: Yes, You Can — With the Right Prep

So, can you lay pavers over concrete? Absolutely — if the slab is in good shape, level, and well-drained. It's a smart, cost-effective way to upgrade your space without the headache of tearing everything out.

But it's not a one-size-fits-all answer. If you're unsure whether your slab is suitable, our team of concrete contractors in Portland at Xcelent Concrete Services is happy to evaluate it for you — for free.
