A Comparison Between Exposed Aggregate and Concrete Pavers
You can use exposed aggregate to construct your driveway. You can also use concrete pavers. This article discusses those two options so that you can make an informed decision when choosing the material for your new driveway.
Exposed Aggregate Driveways
This driveway is made in two different ways. First, the contractor may pour a concrete mixture. Once it sets for a while, he or she may wash off the smooth layer on the surface so that the bigger particles in the concrete mix (the aggregates, such as pebbles) can be exposed on the surface of the driveway.
The second option is to pour aggregates on the surface of a newly poured concrete base. This driveway may take a short time to complete because the contractor can use a machine to pour a large volume of concrete on the entire driveway within a short time. This mechanisation may make the installation cost more affordable.
The other advantage of exposed aggregate driveways is that you can customise the appearance of the surface by choosing a specific colour for the exposed aggregates. You can also choose a pattern that the large aggregates should adhere to. The exposed aggregate increases traction on your driveway so vehicles are less likely to skid when the surface is wet. The downside of exposed aggregate driveways is that they may be damaged easily if you live in an area that is subjected to extreme temperature variations. Freeze-thaw cycles cause the concrete to crack over time. The concrete mix also needs to be poured during the dry periods of the year, so there is a time limit on when this driveway can be constructed.
Concrete Paver Driveways
Pavers are made in a factory using a mould before being shipped to a construction site. The individual pavers are arranged one by one over a sand base to form a pattern desired by the homeowner. The installation process for a paved driveway is labour-intensive and time consuming because no automation can be used during the installation process. This may increase the installation cost. However, pavers are ideal for locations that experience weather extremes. This is because the gaps in the pavers allow the driveway to adjust to the heaving underneath it during freeze-thaw cycles. Thus, pavers are less susceptible to weather damage when compared to exposed aggregate driveways.
As you can see, both kinds of driveways have strong points and shortcomings. It is therefore very important that you weigh those pros and cons with the help of a driveway professional before you make a final decision.
