Repairing Interlocking Concrete Pavers

 

A backyard patio can be a great addition to any home. You can hose barbecues with the neighbors or small family get together lasting all day.  Of course, a backyard patio can be complicated to maintain, particularly if you use interlocking concrete pavers.  Over time you can encounter some problems so make sure you conduct regular Permasealgta.com maintenance and address problems immediately as you find them.

MAINTENANCE JOB #1:  Repairing an Uneven Paver Surface

When interlocking concrete pavers are uneven it is often because they have been installed on a base that is not quite deep enough. It might also be that they are not of the right thickness. Of course, these are two things you should look into before setting about the job and if this is, in fact, the case, it might make the most sense to simply remove them all and start over, doing it right this time.

Still, uneven interlocking pavers could be the result of sand, weeds, dirt, or debris which could have worked their way between and beneath the tiles.  A pressure wash might be an easy fix or you may have to get down and do a little handiwork.

MAINTENANCE JOB #2:  Varying Degrees of Uneven Paver Height

A problem like this typically happens when landscapers use stone dust, which is a byproduct of screening, often naturally occurring in gravel pits.  But more important, this material can continue to break down, refining and refining the more it is compacted and installed under the interlocking concrete pavers.  This dust can retain moisture, acting a bit like clay after it freezes and thaws.

If you find this is the problem, it may require a complete reinstallation of the pavers. Knowing this, you can avoid the problem a second time (or from the beginning) by using 3/4” processed gravel with particles of different sizes; this way you get even compaction.

MAINTENANCE JOB #3:  Border Pavers Falling Off

Most of the time, this problem is the result of pavers that are installed without any edge restraint to hold the pattern together.  Fixing this problem typically means pulling the pavers up and then adding more base and more sand. Then you will want to install an edge restraint to hold them in place.
