Caring for your new concrete
Concrete is a strong, durable paving product, but like all cement-based materials it is affected by curing, moisture, temperature changes, and freeze-thaw cycles. Small cosmetic variations and minor surface changes can occur as part of normal concrete behavior. Here are some tips to care for your investment:
-
Avoid de-icing salt and clear snow and ice
Do not use de-icing salt during the first and second winter if possible. Salt can increase the risk of surface scaling during freeze-thaw cycles while the concrete is still relatively new. Sand is a safer option for traction during that period. Even salt dripping from vehicles can cause damage on new concrete. Concrete driveways should be fully cleared of snow and ice and allowed to dry whenever possible. Driving over compacted snow and ice that is not cleared can force salty water into the concrete, greatly increasing the chance of spalling, especially when vehicle traffic also causes mechanical stress over areas with absorbed frozen salty water. (Salt damage is NOT covered under the concrete warranty.)
-
Wait before driving or parking
Do not drive or park on the concrete surface for at least 7 days during summer months. This is dependent on weather - in cooler seasons or damp conditions more time may be needed for the concrete to cure properly. Heavy vehicles should be kept off longer. Driving on concrete too early can cause surface damage, cracking, or permanent weakening.
-
Spread concentrated loads
Do not place heavy concentrated loads on the new concrete surface for the first few weeks. Items such as dumpsters, loaded bins, jack stands, narrow equipment wheels, or other point loads can damage the surface before the concrete has reached full strength. Use a board to spread the load when safe to do so.
-
Clean spills and harsh chemicals
Do not allow oil, gas, grease, fertilizer, or other harsh chemicals to sit on the concrete surface for extended periods. While concrete is more resistant than asphalt to petroleum products, staining and surface deterioration can still occur. Clean spills as soon as reasonably possible.
-
Use gentle snow removal methods
Do not use metal shovels or aggressive snow removal methods that may chip or scratch the surface, especially on decorative or broom-finished concrete. Plastic shovels or rubber-edged equipment are preferred where practical.
-
Understand normal surface changes
Do understand that small hairline cracks, minor shrinkage cracks, slight colour variation, and the occasional stone pop can be a normal part of concrete curing and long-term performance. Control joints are placed to help manage cracking, but concrete does not always crack exactly within those joints.
-
Keep the surface clean and well drained
Do keep the surface clean and maintain proper drainage around the slab. Avoid allowing water to pond on or beside the concrete for extended periods, especially through freeze-thaw conditions, as excess water can contribute to movement or surface wear over time.
-
Avoid loads the slab was not designed for
Avoid very heavy vehicles or equipment driving on your concrete, unless the slab was specifically designed for heavy use, as it may cause cracking or settlement. Most residential concrete is engineered to support regular vehicles and light trucks on a regular basis.
