Your concrete will inevitably crack or develop holes, and it’s important that you know what to do when this happens in order to prevent it from worsening. Unfortunately, fixing a concrete hole in your driveway is not as easy as simply pouring more concrete directly into the hole. Before you start your repairs, there are three steps you must take.
Step 1. Level the hole
It’s always important to level the bottom of the concrete hole so that the new concrete doesn’t pop out later on. You can use a cold chisel and a hammer to perform this step. Afterwards, clean out the excess concrete and dirt from inside the hole using a wire brush, water, and a vacuum.
Step 2. Painting on a concrete bonding liquid
After the hole has been leveled, pick up some concrete bonding liquid from your local home center and start brushing the inside of the hole.
Step 3. Mix your concrete
While the bonding liquid is drying, start mixing your concrete with water. You will want to start filling the hole while the bonding agent is still tacky.
Starting the Pour
You can start pouring your concrete into the hole after you’ve finished mixing it and before the bonding agent has completely dried. Make sure you press it evenly with a trowel into each corner and against the edges. Once the hole is filled, leave some concrete mounded on the top and level it with a straight-edged board. This board should be at least 12 inches longer than the hole’s width. Moving it back and forth as you level the top of the hole will smooth everything out and firmly pack down the concrete.
After the newly poured concrete feels firm to the touch and no longer appears wet, you can smooth it with a wood or magnesium trowel (don’t worry, this will not hinder the curing process). Use a fanning motion with this trowel to blend out the edges of the new concrete into the existing concrete. You will want to repeat this process quite a few times as the mix cures. Finally, make sure to wait at least 24 hours before walking across the newly-filled hole, and at least one week before parking or driving on it.
Fixing a concrete hole doesn’t have to be so complicated.
