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.

✓ Drill holes through the slab.

✓ Pump grout mixture through the holes. This mixture will spread out beneath he driveway and raise it up.

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

This is a process that works to efficiently get your driveway back in a top condition relatively quickly.

Generally, a paved driveway is always subjected to regular usage and yours isn’t likely to be an exception, otherwise you won’t be here. Regular usage automatically necessitates regular maintenance of the driveway in order to extend its lifespan, make your property safer and add more value to it. This maintenance will involve a frequent inspection of the paved driveway so as to identify and repair divots, cracks as well as rutting. Paved driveways usually have a lifespan ranging between 15 to 20 years, but this can only be guaranteed when backed by regular maintenance activities. Failure to provide your paved driveway with a regular maintenance will lead to a rapid deterioration within just a couple of years after installation.

The issues commonly faced by paved driveways is usually different based on several factors such as the weather, your location, your property’s sub base as well as some other elements. The ability to identify the problems and solve or repair them on time is key to success while it’s also save you some time and money. In this article we’re going to look at how to go about do-it-yourself tasks that involves minor cracks. More intense damages are advised to be handled only by professionals.

✓ Prepare the area. Clear the debris, weed the plants or vegetation (if any).

✓ Use a strong spray from a garden hose to wash clean the cracks

✓ In the event whereby the crack is deep, simply fill it until it reach about a quarter inch of the surface with sand.

✓ Tamp down the sand to make it more compact.

✓ Apply a patching compound to the surface of the cracked paved driveway.

✓ Leave it for some time to cure.

✓ Once cured, you can then apply your sealant.

1. Prepare the base If you want your resin bound driveway to last a long time, you need to ensure that you prepare the base properly. Remove any block paving, grass or soil and dig down until you hit solid ground. Lay a sub-base of asphalt for good permeability. If you’re laying over the top of your current driveway, make sure that all cracks are increased into a ‘v’ shape with a saw and ensure the surface is dry and weed-free.
2. Mix the resin You must follow the instructions on the materials you have to the letter if you want the curing process to work. Usually batches come in ‘Part A’ and ‘Part B’. Keep the resin container secure and on a protective surface to avoid splashing, then mix Part A for 10-20 seconds at a slow speed with a helical bladed mixer. Add Part B and mix thoroughly at a slow speed for about 2 minutes until it’s blended together.
3. Mix the dried aggregates and sand with the resin Place a quarter of the aggregates into a mixer, then add the pre-mixed resin and start a stopwatch. You should then add the rest of the aggregates before slowly adding the sand. When you’re happy with that mix, stop the stopwatch. That time is the time that you need to spend mixing any other resin and aggregates to avoid colour variation.
4. Lay the mix on the surface Transfer the mix to the work area then plan a laying route. When the mix is laid out, use a very clean trowel to spread the mix. Clean it regularly during the process to avoid dragging aggregates out of place. Once the aggregates stop moving in a fluid movement and become solid, stop trowelling. Then you can polish the surface to give it an attractive shine.

Driveway surfacing materials like concrete, asphalt and clay brick usually crack because they’ve been exposed to extreme temperatures or put under high pressure. It’s important to repair driveway cracks before they get worse and cause damage to vehicles and perhaps others to trip on raised cracks.

Do you want to install a new patio? If yes, then on top of the agenda will definitely be the cost of paving slabs.

Secondly, there’s a need to consider the drainage because failure to provide adequate drainage will only result in storing of water which leads to a development of algae or vegetation across your patio.

The material you opt for is also a huge determinant of your patio’s cost. When it comes to paving slabs you’ll only get what you pay for. Deciding to go for cheaper paving slabs will most likely lead to frequent staining, slippery surface, tough maintenance as well as constant cracking. Consequently, the act of cutting back on the cost of paving slabs will only you cost you more money in the long run. What’s more? If you have an existing patio you’d like to replace, then you’d probably need to include the cost of removing the existing one.
