How To Repair Interlocking Pavers

How To Repair Interlocking Pavers

If your home has a patio consisting of interlocking concrete pavers, you will, undoubtedly, run into a few problems that will need a little care to solve. Of course, you don’t have to address many of these problems right away, but if you want your home’s aesthetic appeal to remain consistent—and you want to avoid the hard work later—you should perform all maintenance and upkeep on a regular basis, and as immediately as possible.

REPAIR #1: Uneven Paver Surface

If your Perma-Seal GTA concrete pavers surface is uneven there is a good chance they have been installed on a base that is not deep enough in the ground or not of even thickness.  To repair this problem could require you to start over from scratch because the problem is the foundation and not the pavers themselves. However, starting from scratch ensures that you can do it right all at once. Of course, you could simply check that the pavers are even as you install them, to begin with.

But, you might get lucky. Maybe sand or weeds or dirt or other debris has worked their way between and beneath the tiles. You may be able to fix this problem by hand or using a pressure washer to wash away the debris.

REPAIR #2: Uneven Pavers at Different Heights

This problem often occurs when a landscaping project uses stone dust. Stone dust is a by-product of screening that happens naturally in some gravel pits.  This material can continue to break down into an even more fine dust when compacted and installed beneath concrete pavers.  The dust retains moisture and acts kind of like clay when it freezes and then thaws.

As with an uneven surface, uneven pavers at different heights may need a full replacement job to fix the problem. However, to avoid this problem, consider using 3/4” processed gravel with various-sized particles to ensure even compaction.

REPAIR #3: Border Pavers are Falling Off

Generally, this problem happens when pavers are installed without edge restraint to hold the pattern together.  Fixing it means pulling up the pavers and adding more base and sand beneath them and then installing an edge restraint when replacing the concrete pavers.
