Build it to Last: How Deep Should You Dig for Hardscaping in Southwest Florida?

Hardscaping is more than just laying stone — it’s about creating a foundation that can withstand Florida’s unique climate. Whether you're installing a patio, driveway, or walkway, the key to a durable and beautiful hardscape in Southwest Florida starts below the surface.

So how deep should you dig? And how much base rock is enough? Let’s break it down.

Why Proper Excavation Matters

Southwest Florida’s sandy soils and frequent rain make a strong foundation absolutely essential. Without the right preparation, pavers can shift, settle, or develop drainage issues within months of installation — especially under heavy foot or vehicle traffic.

Recommended Excavation Depth for Hardscaping Projects

Here’s a general rule of thumb for digging:

• Walkways & patios:
  Excavate 6 to 8 inches below finished grade.

• Driveways or areas with vehicle traffic:
  Excavate 10 to 12 inches to ensure long-term stability.

This depth includes room for your base rock and sand layer before the pavers are installed.

How Much Base Rock Should Be Used?

After excavation, the next step is building your base:

• Walkways & patios:
  Use 4 to 6 inches of compacted base rock (also known as crushed limestone or road base).

• Driveways:
  Use 6 to 8 inches of compacted base rock to handle the added weight of vehicles.

Always compact in 2-inch layers using a plate compactor — this ensures each layer is solid before the next is added.

Why Base Rock is So Important

Base rock serves several purposes:

• Stability – It distributes weight evenly, preventing pavers from shifting or sinking.

• Drainage – Properly compacted base rock promotes drainage and minimizes pooling.

• Longevity – A solid base means fewer repairs and longer-lasting hardscapes.

Skipping or skimping on base material is one of the most common — and costly — mistakes in hardscaping.

What to Watch Out For: Common Shortcuts in Hardscaping

Unfortunately, not every contractor plays by the rules. To save time or increase profit margins, some companies will:

• Dig shallow – Only going down 3–4 inches instead of the recommended 6–12.

• Use minimal or no base rock – Leading to premature sinking and paver failure.

• Skip compaction steps – Laying pavers over loose or uneven base material.

• Cut corners on drainage – Causing water to pool or damage surrounding landscaping.

These shortcuts may not be obvious right away, but within a year, the problems often start to show — especially in Florida’s rainy season.

How to Tell If a Contractor Is Cutting Corners

Ask these questions during your consultation:

• How deep will you excavate, and why?

• What type and depth of base material will you use?

• Will you compact the base in multiple layers?

• Can I see past examples of similar projects?

If the answers are vague or the contractor seems rushed, that’s a red flag.

At Precision Landscaping, we educate every client on the “why” behind our process. We believe craftsmanship starts from the ground up.

Final Step: Bedding Sand Layer

On top of the compacted base rock, add 1 inch of bedding sand before laying the pavers. This final layer helps level the surface and locks everything in place once compacted and sealed.
