Polymeric Sand in Ottawa

Polymeric sand strengthens joints, reduces weed growth, and keeps your interlock looking crisp.

What is polymeric sand?

Polymeric sand is a binding material that fills the joints between interlocking pavers and hardens when activated with water. It's a major upgrade over regular sand—it resists washout from rain, prevents weeds and ants from pushing through the joints, and gives the surface a cleaner, more finished look. Our polymeric sand service includes cleaning the joints, removing old sand, sweeping in the new product, compacting it into the gaps, and activating it with a controlled mist. We use premium-grade polymeric sand that's flexible enough to handle expansion and contraction through seasons. This service works great on its own or as the final step after a pressure wash, and it's one of the most cost-effective ways to refresh an aging interlock surface.
