Your residence’s exterior concrete slabs are made to be durable, but routine care can go a long way in keeping them strong and looking their best.  The good news is that it doesn’t have to be complicated as just a few simple maintenance steps can extend the life of your concrete slabs considerably as well as keeping them appealing to the eye, safe, and structurally sound.  Here are some key tips for concrete slab maintenance:

Regular Cleaning

• Using a hose or power washer with mild detergent, clean the concrete surface regularly to remove dirt, debris, mold, vegetation, and stains.  Try to avoid using harsh chemicals that can degrade the concrete over time.

Maintain the Concrete’s Seal

• Apply a concrete sealer every 2-5 years to protect against moisture, oil, and chemicals.  Always choose a sealer based on the location and usage (e.g. penetrating sealers for driveways, film-forming sealers for patios).  Ensure that the concrete’s surface is completely dry and clean before applying the sealer.

Repair Cracks Early

• Small cracks can be repaired with a concrete crack filler or patching compound.  Always address cracks as soon as they appear to prevent water infiltration which can compound the damage.  Larger cracks may require professional assessment and repair.

Control Water Drainage

• Ensure that proper drainage is ongoing to prevent water pooling on or around the slab as this can lead to erosion or cracking.  Use gutters, downspouts, and proper grading around the slab to direct water off and away.

Protect Against Heavy Loads

• Avoid parking or placing heavy loads on areas that are not designed to bear excessive weight.

Monitor for Signs of Settling

• Check for uneven surfaces which could signal settling or sinking and may require professional leveling techniques.

Control Vegetation

• Discourage roots and plants from growing too close to the slab as they can be invasive, causing cracks and destabilizing the concrete.  A good preventative measure is to use barriers or edging to keep the vegetation isolated.

A well-maintained concrete slab performs better, lasts longer, looks better, and saves you from costly repairs!
