What is Interlock Repair?
Interlock repair is the process of identifying and correcting the underlying causes of failed or uneven pavers rather than simply masking the problem. Over time, issues such as poor base preparation, soil settlement, water infiltration, freeze-thaw cycles, and improper slope can lead to sinking pavers, pooling water, trip hazards, loose steps, and shifting edges. At Seal-It Group, interlock repair involves carefully lifting the affected pavers, diagnosing base failure, adding or replacing granular material as needed, regrading for proper drainage, and mechanically compacting the base before relaying the pavers and reinstating polymeric sand. This method restores structural integrity, safety, and appearance—extending the life of your existing interlock and often eliminating the need for costly full replacement. Our specialized repair crews focus on precision, durability, and long-term performance, ensuring your interlock functions and looks the way it was always meant to.
Why Choose Interlock Repair
Interlock repair is the smart alternative to full replacement when your pavers are structurally salvageable but failing due to base issues, settlement, or drainage problems. Rather than tearing everything out, professional repairs target the exact problem areas—saving you time, money, and unnecessary disruption. When done correctly, interlock repair restores proper slope, stability, and safety while dramatically improving appearance. It extends the lifespan of your existing interlock, eliminates trip hazards and pooling water, and preserves the original investment in your hardscape. With specialized repair crews, proven processes, and a focus on correcting the root cause—not just the surface—interlock repair delivers long-term results without the cost of a full rebuild.
What Interlock Repair Can Help With
Structural Correction, Not Cosmetic.
Interlock repair addresses the structural issues beneath the surface—not just what you see on top. It corrects problems such as sinking or unlevel pavers, pooling water, trip hazards, loose or shifting steps, tire depressions, and negative slope toward the home. By repairing base failures, improving drainage, and restoring proper compaction, interlock repair stabilizes your hardscape at its foundation, preventing recurring issues and extending the life of your existing interlock.
Key Benefits
Interlock repair fixes the underlying cause of failure—base issues, settlement, and drainage problems—rather than hiding symptoms at the surface. The result is a safer, longer-lasting, and properly functioning interlock system.

The Process
Our specialized repair crews follow a structured process designed to properly diagnose and correct the underlying issues affecting your interlock. Every step is performed with care and precision to ensure a reliable, long-term repair.
Lift & Assess
We carefully lift the affected pavers and assess the underlying conditions to identify base failure, settlement, and drainage issues causing the problem.
Correct the Base
Failed or compromised base material is removed and replaced as needed, then regraded to achieve proper slope and long-term stability.
Compact & Prepare
The repaired base is mechanically compacted in lifts to prevent future movement and ensure a solid foundation for the pavers.
Relay & Finish
Pavers are reinstalled with precision and locked in place using polymeric sand, restoring a clean, level, and durable finished surface.

How much will my interlock repair cost?
Interlock repair costs vary depending on several factors, including the size of the affected area, the complexity of the repair, access to the site, base conditions, and drainage requirements. Our team completes a full on-site assessment to identify the root cause and walk you through the most effective repair options before providing clear pricing.
What is lift & relay interlock repair?
Lift & relay is a repair method where existing pavers are carefully removed, the base beneath is corrected or rebuilt, and the same pavers are reinstalled to restore proper level, drainage, and stability.
How do I know if my interlock needs repair or full replacement?
If your pavers are structurally sound but uneven, sinking, or pooling water, repair is often the best solution. Full replacement is typically only necessary when the stone itself is severely damaged or beyond reuse.
Will my existing pavers be reused?
Yes. In most cases, your existing pavers can be reused, preserving the original look of your space while avoiding the cost and waste of full replacement.
How long does interlock repair take?
Most lift & relay repairs are completed within one to two days, depending on the scope of work and the extent of base correction required.
How long will a properly repaired interlock last?
When the base is corrected, properly compacted, and graded for drainage, interlock repairs can last many years and significantly extend the lifespan of your hardscape.
Real Clients. Real Results.
We found Seal It on Home Stars and made the right choice in hiring them to replace our front steps and refit and level patio pavers after a parging job. Alex and his crew did an amazing job, installing new natural stone front steps and fixing up our old paver patio. Everyone worked so hard! We were very impressed and are very pleased with the results! You will be too if you choose Seal It.
