The Pros and Cons of Concrete Pavers

Concrete pavers are a popular modular building material used for driveways, sidewalks, patios and more.  Composed of cement, sand, gravel and possibly colouring pigments, concrete pavers can be molded into any number of sizes, shapes and colours.  To help you understand more about these building blocks, we’ve put together a list of the pros and cons of concrete pavers.

 

Strength And Stability

Concrete pavers are considered more than twice as strong, and possibly four times as strong, as regular poured concrete.  Part of this has to do with the manufacturing process of concrete pavers.  After the wet mix is poured into a mold, the mold is vibrated at high speed to cause extra compression before it dries.  And the fact that concrete pavers are distinct, individual units allows weight to be spread over several pieces to reduce the potential for any damage caused by a heavy load.  On the other hand, because of these discrete units, it’s possible for single pavers to be more easily displaced by frost heaves, tree roots and ground subsidence.

 

Installation And Repair

When it comes to concrete paver installation, a lot more precision and care needs to be used.  The base into which the pavers are placed needs to be properly prepared and each paver needs to be carefully set into place individually.  It’s a much more painstaking job than simply pouring a concrete pad.  On the other hand, if a concrete paver gets damaged, it’s a simple job to replace it with a new one.  If a concrete pad is cracked or damaged, the only way to truly repair it is to replace the entire surface.

 

Maintenance And Design

Although it’s said that concrete pavers require little maintenance, the fact that there are joints between the pavers means that they must be regularly monitored.  Weeds and other plants have a tendency to grow in the cracks which can begin to cause damage if left unattended.  Protective sealants might need to be applied on a regular basis to keep the pavers and the gaps in between clean and free of growth.  However, the same spaces that allow weed growth also makes it possible to create pleasing designs.  Concrete pavers can be arranged in incredibly artistic ways that can give your property a curb appeal that could never be replicated with a concrete or asphalt pad.
