Is it Normal for Pavers to Sink Over Time?

What are Pavers?

Pavers are versatile hardscape materials commonly used for driveways, patios, and walkways. Made of concrete, brick, and natural stone, pavers provide both aesthetic appeal and function for homeowners.

The Basics of Paver Installation

Laying pavers correctly involves more than just placing stones. You must prepare a solid base, ensure proper drainage, and set the pavers in an interlocking pattern. A good base is key – a compacted gravel layer topped with sand, then the pavers are laid level and fitting together tightly.

Why Pavers Sink?

Soil Erosion Below Pavers

One of the primary reasons pavers sink is due to soil erosion underneath them. Over time, water can wash away the soil, creating voids where the pavers no longer have support. This is especially common in areas with heavy rainfall or improper drainage.

Improper Base Materials

Using the wrong base materials or not compacting the base properly can cause pavers to settle. For example, using dirt as a base means your hardscape may sink significantly.

Drainage Issues

Poor drainage can cause water to accumulate underneath pavers. This leads to erosion and freezing/thawing, which destabilizes the base.

Natural Ground Settlement

Over time, the ground naturally settles which can make pavers sink. This is especially true for newly developed areas with unset soil.

Signs Your Pavers Are Sinking

Visible Dips

The most obvious sign is dips and uneven spots in your paver patio or walkway. These sunken areas mean the base was improperly prepared or has eroded.

Post-Rain Puddles

Puddles that form on paved areas after it rains can indicate sunken pavers. This means water isn’t draining properly.

Cracks and Gaps

Cracks and widening spaces between pavers can be a sign of sinking or shifting. This could be from an improperly compacted base or other issues.

Consequences of Ignoring Sunken Pavers

• Sunken pavers are a tripping hazard. Especially in high-traffic areas, uneven pavers can lead to accidents and injuries.
• Ignoring sunken pavers can lead to accelerated wear and tear. The uneven surface can cause increased pressure on certain pavers, leading to cracks and breaks.
• Sunken pavers can be an eyesore and can reduce the aesthetic appeal of your property. This can potentially lower your property’s value, especially if potential buyers see it as a sign of neglect.

Fixing & Preventing Sinking Pavers

Assess the Problem

Before any repair, it’s essential to evaluate the extent of the damage. This might involve removing the pavers in the affected area to inspect the base.

Lift, Reset and Rebuild the Base

To repair, lift sunken pavers, add fresh base material, and compact it well. Using the right base and proper compaction is key.

Proper Installation Techniques to Prevent Future Sinking

To prevent pavers from sinking in the future, ensure a well-compacted base, use appropriate materials, and ensure proper drainage. Hiring experienced contractors can also make a difference.

Drainage is Crucial

A good drainage system is essential to channel water away from the pavers, preventing erosion and water accumulation.

Recommended Upkeep

Inspect pavers regularly for signs of sinking or damage. Ensure proper drainage and consider sealing pavers to protect them from water exposure and erosion.

Regular Maintenance

We emphasize the importance of regular maintenance. Over time, even the best-laid pavers can face issues due to natural elements. Regular inspections can help identify and rectify problems before they escalate.

While it might be tempting to opt for cheaper materials or contractors, Atlantic Brick and Stone caution against this. Investing in quality materials and skilled contractors might seem expensive initially, but it saves money in the long run by reducing the need for repairs and replacements.

Drainage is Key

One of the most common reasons for paver sinking is poor drainage. We have consistently highlighted the importance of a good drainage system. It’s not just about channeling water away from the pavers but ensuring that the entire landscape is designed to prevent water accumulation.

Client Education

Atlantic Brick and Stone believe in educating their clients. A well-informed homeowner can make better decisions regarding their hardscaping needs.

Final Words

While some settling is expected over time, the significant sinking of pavers is not “normal” and often indicates underlying issues. Proper installation and maintenance are key to preventing this.
