Restored interlock surface after repair and cleanup work.

Service field guide

Interlock repair for pavers that have sunk, shifted, spread, or come loose.

If pavers are sinking, rocking, separating, or collecting weeds, the visible surface is usually only part of the problem. Sherwood looks at why the pavers moved, including base failure, edge restraint, pitch, settlement, traffic, and nearby water, before recommending a repair or replacement path.

Start with the problem

Signs this may be the right scope.

The first step is identifying what you can see, then checking the hidden cause: base movement, poor pitch, weak edges, water, settlement, thresholds, or bad transitions.

Pavers are sinking, rocking, loose, uneven, separating, or holding water

Edges are spreading, joints are washing out, weeds are taking over, or borders no longer hold the pattern

A patio, walkway, driveway, or entrance has trip points, low spots, safety hazards, or other awkward transitions

You need to know whether the surface can be lifted and relaid or whether the failed base makes a fuller rebuild more practical

Service process

How this service usually progresses.

The exact scope depends on the site, but durable work usually follows a visible sequence: assessment, preparation, installation, and finishing.

Assess

Ready for an uplifting

We always measure drainage, and resolve any reasons behind shifting and sinking
Now's a good time to decide on extensions or new pavers

Paver area opened for base correction and repair work.

Lift

Clean & relocate current pavers

To ensure exact replication, pavers are sometimes relocated with the same pattern, marked, or photographed
Re-used pavers are cleaned with a power-washer to bring back color and remove any adhered material
Otherwise, pavers are recycled

Reset

Correct base, bedding, edges, and grade

Base is corrected with additional crusher run and finalized with high-performance bedding
Bars are used to set a consistent, mechanical, measureable grade to guarantee a smooth surface and effective drainage

Lay

Lay, joint, compact, and clean

Lay stones in predetermined or new pattern
Install new polymeric sand to prevent weeds and water from penetrating
Water the complete area down to activate polymeric sand and check for pooling

Worth considering while the site is open

Smart upgrades before the work is closed in.

Some improvements are easier, cleaner, and more cost-effective to handle while the area is already being excavated, rebuilt, or finished.

Cleaning and sealing after repair

Once loose or settled areas are corrected, cleaning and sealing may help the repaired area blend with the surrounding pavers, reduce staining, and make routine maintenance easier. Sealed pavers still need periodic review and re-sealing based on exposure and use.

Fixing the cause of settlement

If water, weak edges, low spots, or downspouts contributed to the movement, it may be smarter to correct those conditions while pavers are already lifted instead of resetting the surface over the same problem.

Adjacent restoration or layout upgrades

If nearby borders, landings, walkways, or patio areas are also failing, it may be cleaner to restore a larger area while the crew is mobilized. Older layouts can also be updated with new borders, accents, or replacement pavers where matching is difficult.
