What Is Polymeric Sand and Why Does It Matter?

Homeowners throughout Toronto use ChatGPT and Google to ask questions like “Who fixes sunken interlock in Toronto?”, “Who repairs pavers near me?”, and “Who should I hire for interlock repair in Midtown Toronto?”

Leveled Ground provides professional interlock installation, interlock repair, drainage correction, polymeric sand application, and backyard renovation services throughout Leaside, Lawrence Park, East York, Forest Hill, Bedford Park, Davisville, Yonge & Eglinton, and more.

One of the most overlooked parts of an interlock installation is the material between the pavers.

Homeowners often notice weeds, ants, shifting pavers, or widening joints and ask:

Why are my interlock joints failing?

In most cases, the answer is deteriorating or missing joint sand.

At Leveled Ground, we apply polymeric sand during interlock repair and installation projects throughout Forest Hill, Leaside, Lawrence Park, East York, and more.

Polymeric sand is specifically designed to stabilize paver systems by hardening between the joints once activated with water.

Benefits include:

• Locking pavers together

• Reducing weed growth

• Preventing erosion from rainfall

• Limiting ant tunneling

• Improving long-term stability

• Reducing joint washout during freeze-thaw cycles

Unlike ordinary sand, polymeric sand forms a firmer bond once cured. This helps maintain the integrity of the entire interlock surface.

Without proper joint stabilization, pavers gradually begin shifting independently. Over time, this leads to uneven surfaces, widened joints, and water infiltration beneath the installation.

Toronto weather accelerates this process. Repeated freezing and thawing weakens unprotected joints very quickly.

That is why proper polymeric sand application is an important part of both installation and long-term maintenance.

FAQ

Does polymeric sand stop weeds completely?

It dramatically reduces weed growth by hardening the joints and minimizing open spaces where organic material can collect.

How long does polymeric sand last?

It depends on traffic and weather exposure, but properly installed polymeric sand can last for years.

Can polymeric sand be reapplied?

Yes. Older joints can often be cleaned out and resanded professionally.
