6 Common Problems with Pavers (and how to fix them).

Interlocking pavers offer a fantastic solution for creating beautiful, durable outdoor surfaces. However, like any construction project, they can face challenges during installation and over time. In this guide, we'll delve into common problems encountered with interlocking pavers and offer practical solutions to ensure your project stands the test of time.

1. Uneven Height:

Problem: Typically, when encountering uneven pavers, it's often due to insufficient depth or unevenness in the base where they're laid. In instances where clay soils dominate the project site, they tend to retain more water compared to sandier soils.

The increased water content in the soil leads to greater expansion during freezing periods, causing the pavers to be pushed upwards. Subsequently, during thawing cycles, the pavers may not always return to their original positions, particularly if there's been displacement of sand or stone underneath them while they were raised or misaligned.

Solution: There is no easy way to solve this issue without starting over. That means taking up the entire project, removing the stone dust and using the processed gravel. It's far better not to cut corners to begin with.

2. Disappearing Fixed Edges:

Problem: The gravel base and sand setting bed have escaped and washed out from under the pavers.

Solution: By incorporating a filter fabric beneath the base and extending it up the sides of the project excavation, this issue can be averted. Remedying just the affected area is feasible without the need to redo the entire project. Simply patching in a piece of filter fabric, adding new base material, and reinstalling the pavers can rectify the situation.

3. Border Falling:

Problem: There was no edge restraint installed.

Solution: Reinforce borders with sturdy materials such as concrete or metal edging, ensuring proper anchoring into the ground. In order to fix it, the pavers need to be pulled up, more base and sand need to be added underneath and an edge restraint needs to be installed.

4. Water Puddling:

Problem: Improper drainage can lead to water puddling on the surface of interlocking pavers, causing safety hazards and potential damage to the installation.

Solution: Grade the base to promote proper water drainage away from the surface of the pavers. Incorporate a slight slope (typically 1/8 inch per foot) to direct water towards drainage outlets or permeable areas. Installing permeable pavers or adding a drainage layer beneath the surface can also help mitigate water pooling.

5. Area Settled:

Problem: A lack of compaction is the biggest reason for an area to settle. Settlement of the ground beneath interlocking pavers can result in uneven surfaces and compromised structural integrity.

Solution: Address settlement issues by lifting and re-leveling settled areas, adding or compacting base material as necessary. Pay special attention to areas prone to settlement, such as around tree roots or areas with poor soil compaction.

6. Stains and Efflorescence:

Problem: Stains from oil, grease, or organic materials, as well as efflorescence, can mar the appearance of interlocking pavers over time.

Solution: Promptly clean stains using appropriate cleaning solutions and techniques recommended by the manufacturer. For efflorescence, mechanical cleaning methods or specialized cleaners may be necessary. Applying a high-quality sealant can help prevent future staining and efflorescence formation.

By proactively addressing these common problems and implementing effective solutions, you can ensure the longevity and beauty of your interlocking paver installation. Remember to prioritize proper preparation, regular maintenance, and prompt attention to any signs of deterioration. With proper care, your interlocking paver project will continue to enhance your outdoor space for years to come.
