Creating the perfect patio can transform your Maine backyard into a relaxing oasis or a vibrant gathering space. However, the difference between a dream patio and a problematic one often lies in the details of its construction.

Here, we’ll explore common mistakes in patio paver installation and provide expert guidance on how to avoid them, ensuring your patio is both beautiful and durable.

1. The Case Against Backfilling With Dirt

One of the first steps in laying a patio is preparing the foundation, which involves choosing the right backfill material. While dirt may seem like an easy and inexpensive option, it’s prone to water retention and compaction issues, leading to an unstable base for your pavers.

Instead, opt for road-based gravel. This material offers superior drainage and, when compacted, provides a firm foundation that prevents shifting and sinking, ensuring your patio remains level and intact over time.

2. Not Digging Deep Enough

Another common mistake is not excavating deep enough before starting the paver installation. This oversight can make your patio susceptible to the freeze-thaw cycle, causing the pavers to heave and shift.

To avoid this, ensure you dig to the correct depth, which typically ranges between 4 and 9 inches, depending on how your pavers will be used. This allows enough room for both the gravel base and the bedding sand, creating a stable foundation for your patio.

3. Flat & Firm Gravel Base

Achieving a flat and firm gravel base is crucial for the longevity of your patio. An uneven base can lead to an uneven surface, while a base that isn’t compacted firmly will settle over time, causing pavers to sink or tilt.

Use a plate compactor to evenly compact the gravel, checking for levelness with a spirit level. This step ensures a solid foundation that supports the pavers evenly across the entire patio.

4. Proper Installation of Bedding Sand

After laying the gravel base, the next layer is the bedding sand. Mistakes in this step, such as using too thick a layer or the wrong type of sand, can lead to pavers shifting out of place.

Aim for a uniform layer of coarse, concrete sand about 1 inch thick. This allows for proper leveling and drainage, providing a snug bed for the pavers to sit in.

5. Long Linear Lines of Pavers

When laying pavers, avoid the temptation to install them in long, straight rows. This pattern not only lacks visual appeal but can also lead to structural weaknesses, making your patio more susceptible to shifting and cracking.

Instead, consider staggered, herringbone, or random patterns that distribute weight more evenly and add aesthetic interest to your patio design.

3 Expert Tips for Avoiding These Common Mistakes

When creating a beautiful and durable patio, follow these three expert tips to ensure your project stands the test of time.

  • Materials Selection: Invest in high-quality pavers and base materials. Cheaper options might save you money upfront but can lead to problems down the line.
  • Preparation and Patience: Take your time with each stage of preparation, from excavation to compacting the base. Rushing through these steps is a surefire way to encounter issues later.
  • Precision in Paver Laying: Lay each paver carefully, ensuring it sits level with its neighbors. Use a rubber mallet to gently tap each paver into place, checking for levelness as you go.

By focusing on quality materials, thorough preparation, and precision in laying pavers, you can avoid common mistakes and achieve a professional-looking patio that lasts for years to come.


A well-installed patio not only enhances your outdoor living space, but can also increase the value of your Maine home. By avoiding common mistakes such as using inadequate backfill material, skimping on excavation depth, neglecting base preparation, improperly installing bedding sand, and laying pavers in linear lines, you can ensure your patio is built to last. Remember, patience and attention to detail during installation can save you from costly repairs in the future.
