How Long Do Interlocking Pavers Last

Interlocking pavers are a popular alternative to concrete, asphalt, gravel and other materials when it comes to laying down footpaths, patios, driveways and other areas that require a flat surface.  They’re durable, affordable and provide a wide range of colours, designs and patterns.  They’re often favoured by do it yourselfers in locations that experience harsh winters as they resist cracking caused by extreme weather fluctuations.  But how long do interlocking pavers last?  Properly maintained they can last 50 years or more.  In this article, we’ll provide tips and information on how to get the most out of your interlocking paver installation.


Choosing The Right Pavers

Interlocking pavers come in a variety of thicknesses.  The way in which they are being used will dictate the proper thickness for the job.  Footpaths and swimming pool decks, for example, can be composed of the thinner 60mm pavers, whereas those used for driveways and parking pads should be at least 80mm in thickness.  Interlocking pavers can be used to create incredibly intricate and attractive designs in a wide variety of colours.  Depending on how they’re being used, along with your budget, will influence the right pavers for the job.


Interlocking Paver Warranties

Even though warranties will vary depending on the manufacturer, lifetime warranties on the structural integrity of interlocking pavers are not unheard of.  Although 25 year warranties are more common, the free replacement of a few broken or worn pavers is often well worth the prestige a company receives by offering a lifetime guarantee.  Because manufacturer defects are relatively rare, what should be more closely looked at is the installation guarantee.  Interlocking pavers will naturally settle and shift over time – even more so in extreme weather – so this will likely be more of concern than structural integrity.  


Interlocking Paver Maintenance

Following some simple maintenance procedures every spring will lengthen the lifespan of your interlocking paver surface.  Repeated freezing and thawing typically has the most detrimental effects on any type of hard surface, so an annual spring inspection can greatly extend the life of your driveway or patio.  If you notice shifting or sinking, the offending pavers should be removed, the base relevelled and the paver replaced with polymeric sand swept into the joints.  If any weeds start growing in the spaces they should be removed.  Power washing will brighten up the stones, while applying a sealant every few years will minimize dirt accumulation and damage.
