Polymeric Sand in Ottawa

Strengthen joints on driveways, walkways, and patios against washout and weeds through Ottawa freeze-thaw cycles.

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.

Helps reduce weed growth by hardening and sealing joints.

Stronger joints

FAQ

Common questions about polymeric sand.

+Do I need polymeric sand?

It's not strictly necessary, but we recommend it for most interlock surfaces. Polymeric sand locks the pavers together better than regular sand, reduces weed growth, and resists washout from rain. It's especially worthwhile in Ottawa where heavy rain and snowmelt can quickly erode regular joint sand.

+How long does it take to cure?

Full curing typically takes about 24 to 48 hours, depending on the product and weather conditions. During that time, the surface needs to stay dry and free of foot or vehicle traffic. We always check the forecast before scheduling and will give you a clear timeline for when you can start using the area again.

+Can polymeric sand be added to old interlock?

Yes, it works great on older interlock as long as the joints are properly cleaned and prepped first. We remove the old sand, clean out any debris or weed roots, and make sure the joints are deep enough for the polymeric sand to bond properly. It's one of the best ways to refresh an aging surface without replacing anything.

+Will it stop all weeds?

Polymeric sand dramatically reduces weed growth by creating a hardened barrier in the joints that seeds can't push through easily. That said, no product is 100% weed-proof forever. Over the years, a bit of organic material can accumulate on the surface and give weeds a place to sprout, but a quick pull or spot treatment is usually all you need.

+Can rain ruin it?

Rain before the polymeric sand has fully cured can wash it out of the joints or cause a hazy residue on the paver surface, which is why timing matters. We always check the weather forecast and schedule the work during a dry window with at least 24 hours of no rain expected. If conditions aren't right, we'll reschedule rather than risk a bad result.

+Does it crack?

When installed properly, polymeric sand stays flexible enough to handle normal expansion and contraction through Ottawa's seasons. Some minor cracking can happen in areas with heavy vehicle traffic or if the base underneath shifts, but that's usually a sign of a deeper issue. On a stable surface, it holds up really well for years.
