Can You Lay Block Paving On Top Of Concrete?

The replacement or improvement of your driveway is unarguably one of the most expensive projects you can undertake in the exterior of your home. When done by a true professional the results can be impressive and visually appealing, however you’d have to pay huge bucks to have this done. This is exactly the situation with block paving as it is not only time consuming, but also a lot more expensive when compared to other types of driveway.

A large chuck of this cost is associated with the removal of the existing driveway. So assuming your old driveway is concrete, can you simply pave over the existing concrete? If yes, will it save you money? The simple and short answer is yes. It’s in fact advisable to pave over concrete as this will not only add around 20% to your home’s value, but also make it look a lot more attractive and pleasing to the eye.

However, there are some problems associated with block paving over concrete. It may be better to remove the concrete in situations whereby the base is substandard. For instance, if the ground underneath the concrete is failing, there’ll most definitely be problems.

Also, there’ll be some issues with settling (not even the cracks). If your concrete is dropping little amounts every year, these can affect the blocks and ultimately lead to dropping of some sections of the block paving in such a way that they’ll no longer be on the same level as the other blocks. Giving a rise to the possibility of drainage issues, tripping hazard and lots more.

Other issues that may crop up can be triggered as a result of using the wrong size block height as well as totally ignoring or overlooking the undulations of the concrete.

If you want to give your concrete paving slabs a new lease of life, it’s possible to paint them. This is a great option if your slabs are looking tired or you want a new look, but you don’t want to invest in new paving.

Before you go ahead, you need to make sure that your slab paving is clean and dry. And if it’s been sealed, you’ll need to strip this off. Make sure you get a paint that’s specifically designed for the job so you get the best results.

Spreading gravel on your driveway is usually pretty easy. Tip it into dispersed piles over your driveway area and then use a rake to spread it out evenly. If you’re creating a particularly large driveway and are getting your gravel delivered, you might be able to get help from your delivery driver.

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.

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.
