Cracked or Damaged Driveways and Sidewalks: Should I Repair or Replace the Concrete?

Visible damage to sidewalks and driveways is not only an eyesore, but can also be a liability if neglected. After the decision is made to remedy the damage, the question of whether to repair or replace the concrete will be next. Concrete provider, Razorback Concrete, offers some guidance.

damaged concrete””When you are trying to decide whether to repair or replace concrete that has become cracked or damaged, you must consider whether or not the concrete is worth fixing. Damage that is isolated to one small area of a driveway or sidewalk can often be repaired simply by removing that area and replacing it. Small cracks and isolated damage is often worth fixing rather than taking on the cost of replacement, but in three specific scenarios where the subgrade is at fault, replacement is always the best option.

Sunken Concrete

When the subgrade (the compacted level of soil underneath the concrete) is not properly prepared, such as when loose dirt is used, and the land begins to settle, you might notice unevenness in the slab. The settlement will cause the concrete to sink along the cracks or the seams. Because this problem starts with the subgrade, it requires a full replacement.

Frost Heave

Frost heave is damage that occurs to the concrete when frozen moisture in the ground pushes the concrete up. Again, because this damage occurs due to the subgrade, it requires removal and replacement of the concrete with a new subgrade.

Deep, Widespread Cracks with Settlement

Sometimes the weight of large vehicles or an improperly prepared subgrade can lead to deep cracks. If those cracks spread all the way through the concrete and are widespread across its surface, it will need to be completely replaced. Leaving the cracks will allow moisture to enter the concrete and create even greater damage as it freezes and thaws, thus expanding and contracting.

Who to Call for Concrete Repairs and Replacements

Once you have made the decision about repair or replacement of the concrete, you are ready to make a call to a concrete provider. Get several quotes to ensure you are getting a fair price. Also, make plans for alternate routes or parking space because the area may be unusable for a period of time. Both repairs and replacement usually require subgrade work, and this will make the concrete unusable for the duration of the project.

Calculating the Cost of Concrete Repair or Replacement

While many factors can impact the cost, and only a qualified provider can give a true estimate, the cost for a newly installed standard concrete driveway will run between $6 and $9 a square foot. So, for a 14 x 50 foot driveway, you will spend between $3,500 and $5,600 for a newly installed, plain concrete driveway. Repair costs will vary significantly depending upon the repair technique used.
