How To Repair Sunken Concrete Driveway

If you have concrete driveway that’s cracked, uneven and mostly especially sunken, you’d know how distasteful it can be just viewing it on your property. A sunken concrete driveway is most likely caused by rainwater erosion removing the soil under it or a big root under it which as rotted over time. Another possible cause of the sunken concrete is an improperly prepared base which implies that the soil beneath wasn’t fully compact when the concrete was poured on it. Later on the soil beneath will eventually settle and shift below the concrete driveway which weakens the integrity of the entire driveway, making it more vulnerable to cracks, unevenness and sunken.

Two ways in which you can fix this problem includes either demolishing the whole driveway, re-compact the soil underneath and fill with new concrete or repair the entire driveway using an easy process called slabjacking. In this article, we’re going to look at the slabjacking repair process as it’s significantly less expensive than the demolishing approach and will also cause minimal disruption to your lifestyle.

Also referred to as mudjacking or concrete lifting, slabjacking is simply a process used to float your existing concrete back to its original position. If you are not a competent DIYer or lack confidence to pull this off, we’d recommend reach out to a professional for help. If otherwise, then you can practice the slabjacking process given below.

✓ Lastly, fill the holes and level the concrete driveway surface.in such a way to hide the signs of the repair made.

Pitting, also referred to as spalling is the event whereby “pits” or small holes start showing on the surface of your concrete driveway which makes it appear both worn and uneven. Concrete driveway pitting is a common but highly frustrating problem for most homeowners. You’ll see some concrete driveways that’ll only start to pit after a couple of years, but this is not true for all concrete driveways as others will start to show signs only after a couple of months. So how do you tackle this issue? Well, it’s relatively simple to tackle, however if you’re not confident or lack the necessary skills, we’d recommend you get in touch with a reliable professional who can guarantee the best results for help. In this guide, we’ll take you through the concrete driveway pitting repair process.

✓ Prepare the pits by cleaning the area, clearing out all debris and more. The small pits can be cleaned with a stiff brush while a sturdy broom will do a good job for larger pits.

✓ Make use of a hose to spray the concrete pits and flush out all remaining bits of waste.

✓ If you’re tackling series of small pits, simply use a caulking gun filled with pre-mixed epoxy and specially formulated for concrete to fill the pits. Clear off the excess eproxy ensuring that its level with the concrete surface. Once done, simply leave for at least 24 hours before the application of a concrete sealant to prevent the wear and tear of the new concrete.

✓ Chisel out a little concrete and clean with a pressure washer. Once done, apply a concrete resurfacing compound mixture into the holes and use a trowel to level off.

✓ Ensure that the repaired concrete driveway is protected from rain and foot traffic for at least 6 hours (or 24 hours for vehicles).

Patios do not require lots of maintenance. They will only need occasional cleaning to make sure that the material keeps its original appearance. It's always best to clean your patio with a pressure washer and occasionally tap each slab or brick just to check the sand underneath hasn't washed away.
