Frequently Asked Questions About Paving
How Does Paving Work?
Paving is the process of placing a solid stretch of asphalt or concrete bricks, typically to make a road or driveway. A base supports every stretch of asphalt, which is usually made of compacted gravel. This supports the asphalt and helps keep water from pooling. Once the base is laid, hot asphalt is poured over it and rolled by a power roller to compact it and make it strong. The asphalt is then cooled with water.
Why is Paving Important?
Paving is a great way to maintain a clear path in snowy conditions like we have in Ottawa. As opposed to gravel driveways, which are often difficult to clean of snow and ice in the winter, asphalt can easily be cleared for foot or car traffic. Asphalt is cheap and relatively easy to install. If properly taken care of, it also lasts a very long time.
Can Paving be Done in the Winter?
Yes, it can. The only difficulty with paving in Ottawa is that to be rolled, the asphalt needs to be hot. Of course, if the ground is frozen solid, the asphalt might cool more quickly than it is rolled. Luckily, your professional pavers will know a few tricks to keep it at the proper temperature in the winter.
What are Paving Stones and Slabs Made of?
It depends on which kind of paving stone you have but by and large, they’re made of concrete. Often, however, other materials are added to the concrete to make it different colours or support it in cold temperatures or for some other purpose.
When Should I Seal Paving Stones?
We seal paving stones because concrete can be a porous material. Water can enter these pores and, during the Ottawa winter, expand and contract with the temperature. This swelling of the water as it turns into ice can damage your pavement. You should seal your new pavement about six to twelve months after it’s been put in, to give it time to settle.
Are Paving Stones Fireproof?
“Fire resistant” might be a better way to put it. For most ordinary fires, concrete paving stones will get very hot but no real damage will be done. If you’re having problems with a fire that is hot enough to damage concrete, you probably have more important things to worry about than your pavement.
