Your unistone staircases made to the highest standards

There's more to a paver staircase than just laying a few steps. At Groupe A1, every project is considered in its entirety: solid foundations, proper drainage, perfect alignment and impeccable finishing.

1. Site assessment and preparation

Complete site inspection, identification of constraints (slopes, access, drainage) and project planning for a no-surprise result.

2. Removal of existing surface

Demolition of the old staircase or removal of the unstable floor in order to start again from a sound base.

3. Levelling and slope management

Precise ground adjustment to ensure optimum drainage and avoid water seepage under the steps.

4. Laying the foundation

Installation of a crushed stone base, compacted in successive layers, to ensure the staircase's stability and durability.

5. Sub-base installation

Addition of a layer of levelled, compacted sand to accommodate the pavers evenly and ensure a perfect fit for the steps.

6. Laying uni-paved steps

Each paver is installed with precision, according to the design chosen (straight steps, rounded steps, integrated into a low wall, etc.), for an aesthetic and safe result.

7. Compacting and grouting

Final compaction of the pavers and application of polymer sand in the joints, to solidify the whole and limit weed growth.

8. Cleaning and finishing

Final inspection, adjustments if necessary and complete cleaning of the surface to deliver an impeccable staircase, ready for use.
This rigor makes the difference between a staircase made of solid cobblestones that sags after 5 years... and a flawless staircase that lasts 25 years without compromise.

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.

Is it possible to build a paver staircase on a slope?

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.

Does paving stone stand up well to Quebec winters?

Yes, interlocking paving stones are designed to withstand freeze-thaw cycles. With professional, state-of-the-art installation, your steps will remain safe and stable for decades to come.

Can I choose the color and style of my uni-stone steps?

Yes, paver stones come in a wide variety of textures, formats and colors. You can customize your staircases to match your home and landscaping perfectly.

Do you offer a warranty on paver installation?

Yes, all our work is guaranteed for 2 years. In the event of a problem, our team intervenes quickly to rectify the situation and ensure your satisfaction.
