Common Mistakes to Avoid During Driveway Construction

Installing an interlock paver driveway is a great way to enhance your home’s curb appeal and ensure long-lasting durability. However, improper installation can lead to costly repairs and early failure. Here are some of the most common mistakes homeowners and contractors make during driveway construction, and how to avoid them for a high-quality result.

1. Skipping Proper Base Preparation In Your Driveway

A solid base is the foundation of a long-lasting interlock paver driveway. One of the biggest mistakes in driveway installation is using an insufficient base or failing to compact it properly. A properly prepared base consists of 6-8 inches of tested Granular A or 3/4” crushed stone for walkways and 10-12 inches for driveways, compacted in layers. Without this, pavers can shift, sink, or heave over time, especially in freeze-thaw cycles common in London Ontario.

2. Using the Wrong Screeding Material

Traditional bedding sand is often used as a base for pavers, but using too much of it or improperly compacting it can cause instability. A better alternative is High-Performance Bedding (HPB) or 1/4” crushed stone with no fines, which locks into place, prevents shifting, and allows for better drainage. A quality driveway installer will ensure the right screeding layer is applied evenly and correctly.

3. Ignoring Proper Edge Restraints

Without proper edge restraints, pavers can begin to shift and spread over time. Snap edge restraints or concrete curbing should be installed along the perimeter of the driveway to hold everything in place. Failing to include edge restraints or improperly securing them can lead to a failing driveway structure.

4. Poor Drainage Planning

Water management is crucial for driveway construction. If water pools on the surface or seeps under the pavers, it can cause washouts and frost heave. Ensuring a proper slope away from structures and using permeable pavers or drainage solutions can help manage water efficiently. A quality driveway installer will evaluate the grading and implement necessary drainage solutions.

5. Improper Paver Compaction

Compacting the pavers after installation helps lock them into place. Many inexperienced installers fail to use a plate compactor with a protective pad, which can lead to uneven surfaces or damage the pavers. Compacting in multiple passes with polymeric sand filling the joints ensures long-term durability.

Conclusion

A properly installed interlock paver driveway adds beauty and longevity to your home. Avoiding these common mistakes ensures your investment lasts for years with minimal maintenance.
