Expert Landscape Architects and Designers in Markham, ON

Your interlocking stone doesn't sit directly on the soil. If it did, the stone would shift because the soil expands and contracts. Preventing shifting is one of our priorities, so we take care in preparing a level, solid base for the interlocking stone to sit on. We use 3/4 crusher run gravel in the base, leveling it and making sure it's sloping away from the home to prevent water running towards it. We then add high performance bedding (HPB) on top, a limestone aggregate, that allows water to pass through your stone interlock efficiently.

If you hate weeds, then you might actually believe that magic sand is magic. We use magic sand, also called polymeric sand, in between the interlocking stones to prevent them from shifting and also to prevent weeds from growing through. Once water is applied to the sand, it hardens, and that's when the "magic" happens.

Preventing shifting starts with a good base. We spend a lot of time making sure the base is solid and level, before laying the interlock on top of it. If the area where you are installing interlock is sloped, a retaining wall may be necessary, not only to keep the base and interlock flat, but also to prevent shifting. In addition, we also use edging that is installed at the ends of the interlocked area to keep stones in place, along with polymeric sand (magic sand) between individual stones to keep them in place.

Yes, of course! We guarantee the quality of our work with a two year warranty against shifting or sinking of your interlock so you can be confident when you choose us as your interlock contractor that your driveway interlock, patio interlock or walkway interlock will be hassle free and won't need costly repairs.
