FAQ about asphalt driveways
How much does it cost to install a paver staircase?
Prices vary according to size, number of steps, type of paving and complexity of project. On average, the cost is expressed per square foot or per step. A personalized estimate is always necessary to obtain a fair and accurate price.
What are the advantages of paving stone staircases over concrete?
Unistone pavers offer greater durability, refined aesthetics and the possibility of replacing a single stone in the event of breakage. Unlike poured concrete, it won't crack under freeze-thaw conditions.
Is interlocking paving safe for stairs?
Yes, with proper installation, interlocking paving stones provide excellent stability and a slip-resistant surface. The addition of precise edges and slopes ensures a safe stairway all year round, even in winter.
How long does a paver staircase last?
A well-installed paver staircase can last between 20 and 30 years with minimal maintenance. The key is a solid foundation and proper drainage.

Absolutely. Unistone is highly flexible and can be adapted to the particularities of the terrain. Our teams design bespoke staircases, whether for a main entrance, garden access or sloping landscaping.
How do you maintain a staircase made of uni-stone?
Maintenance is simple: occasional cleaning with water, replacement of polymer sand between joints and, if necessary, straightening of a displaced stone. There are no cracks to repair, as with concrete.
