How To Repair A Cement Porch Separating From The House

Step 1

Clean out the separated area between the house and the concrete porch using a shop vacuum to remove all debris.

Step 2

Place a wheelbarrow near the separation and combine one part cement with three parts masonry sand, then dampen with a hose.

Step 3

Stir up the cement and sand with a masonry hoe, adding more water as necessary. The mixture should become a mud-type consistency.

Step 4

Open a can of concrete bonding agent and pour it directly into the separation between the porch and the home.

Step 5

Tip the wheelbarrow up, allowing the concrete to pour into the gap. Fill the gap completely, then smooth it with a trowel. Scrape up excess concrete as necessary, smooth again, then let dry for 24 hours.

Step 6

Step 7

Apply a coat of concrete sealant to the patch using a paintbrush once the concrete has completely dried. Let the sealer dry for another 24 hours to finish the repair.
