As winter is upon us, it’s time to think about protecting your beautiful interlocking concrete paver pavements, be it a backyard patio, a walkway, or a driveway. Winter snow, ice, and fluctuating temperatures can be hard on pavements, leading to stains, shifting, or wear if they’re not well-prepared. Here’s a simple guide to help you winterize your patio, keeping it in great shape all season.
1. Remove any debris from the surface
Sweep away any dirt, leaves, or debris that’s collected on your patio. Use a broom or leaf blower. Cleaning is key, as dirt and organic matter left on the surface over the winter will stain the pavers.
2. Level Any Uneven Pavers
If some of your pavers have shifted or settled, take some time to level them. Uneven pavers can create areas where water pools, freezes, and complicates snow removal. A raised edge could catch a shovel, snow blower, or snowplow and damage the paver or the snow removal equipment. To fix minor movement less than 1/4 in. (6 mm), lift the affected paver and a few surrounding ones, adjust bedding sand as needed, replace the paver and refill the joints with sand for a smoother, safer surface.
3. Only use concrete-friendly de-icers
Have standard road salt (sodium chloride, NaCl) available for de-icing, as it causes the least damage to concrete surfaces experiencing freeze-thaw environments. Avoid de-icers that include magnesium chloride (MgCl) or calcium magnesium acetate CMA because they significantly increase potential damage. Plan to apply only enough salt to get the job done. Also, consider having sand available to improve traction. When the ice melts it will top up the joint sand. Plan to remove excess salt and sand after the ice is gone.
A bit of preparation now can save you time, money, and effort when spring arrives. By following these easy steps, you’ll keep your interlocking concrete paver patio protected, looking its best, and ready to enjoy as soon as the warmer days return. This winter, relax with the peace of mind that your patio is ready for the cold!
