As temperatures drop and snow begins to fall, your interlock driveway becomes one of the most vulnerable areas of your property. Without proper care, winter moisture, freeze-thaw cycles and de-icing salts can damage even the most durable pavers. The good news? A few simple maintenance steps in the fall can protect your investment and keep your driveway looking its best all year long.
Here’s how to get your interlock driveway ready for the cold months ahead.
1. Give Your Driveway a Thorough Cleaning
Before the snow arrives, take time to remove dirt, leaves and debris that have built up over the summer. A clean surface prevents organic material from breaking down between the joints, which can lead to weed growth or staining when moisture freezes.
How to clean effectively:
- Use a broom or leaf blower to clear away loose debris.
- Wash the surface on a mild day to remove oil or salt residue.
- Let the stones dry completely before moving on to sanding, sealing or repairs.
Pro Tip: Avoid harsh chemicals, eco-friendly cleaners protect both your interlock and surrounding landscaping.
2. Inspect and Repair Cracks or Shifting Stones
Small cracks or uneven areas may seem minor now but can worsen during winter as water seeps in and freezes. The freeze-thaw cycle expands gaps, loosening pavers and compromising the structure.
If you notice any issues:
- Re-level sunken or uneven stones.
- Fill cracks with polymeric sand to stabilize the joints.
- Replace damaged pavers before the first frost hits.
A professional inspection from Enviro-Loc Interlocking Ltd. ensures your interlock driveway remains stable and safe through the season.
3. Determine if the polymeric sand needs changing
Check the polymeric sand between the joints of the pavers for any signs of failure. If you notice the surface of the sand is peeling or the sand is soft to the touch, it may be time to change it out.
Changing polymeric sand is a process that includes pressure washing the surface of your interlocking driveway thoroughly to remove all the sand between the joints. Once dry, a new polymeric sand can be swept in between the joints and wet to inhibit the binding materials.
Following a new polymeric sand installation, the interlocking driveway would not require this interlocking maintenance again for 3-6 years.
4. Apply a Quality Sealer for Interlock Protection
A sealer for interlock is your best defense against moisture, salt and stains. High-quality sealants create a protective barrier, reducing water absorption and enhancing the stone’s natural colour.
When and how to seal:
- It is ideal to apply a sealer coat following a new sand installation.
- Seal only after the surface is fully cleaned and dry.
- Choose a breathable, eco-friendly sealer that resists salt and oil.
- Reapply every 2–3 years for lasting protection.

5. Use the Right Snow Removal Tools
Traditional metal shovels and ice chippers can scratch or chip interlocking stones. To avoid damage:
- Use plastic or rubber-edged shovels.
- Avoid metal blades or snowblower augers that make direct contact with the pavers.
- If you use a snowblower, keep the blades slightly raised.
Tip: Contrary to recent belief, rock salt is your best defence against ice. Use it sparingly and only when needed to de-ice your interlocking driveway.
6. Maintain Proper Drainage
Poor drainage leads to ice buildup and water pooling, which can weaken your interlock base. Make sure your driveway slopes slightly away from your home and that any drainage channels are clear of debris.
If you notice water pooling after rain, it may be time to re-grade or re-sand specific sections, a quick fix that can prevent major issues come spring.
7. Extend the Care to Your Backyard Interlock
Don’t forget that the same principles apply to your backyard interlock patios, walkways and pool decks. Cleaning, sealing and protecting these areas ensures consistency in both appearance and performance throughout your property.
