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.

1. Start in one corner of the sub-frame and position the first board across the inner joists. You want the deck board in the opposite direction to the inner joists, ensuring that it’s flush with the frame. Position any end-to-end joins between the deck boards halfway across an inner joist so you can screw both boards into the joist for stability. Make sure you keep a gap of between 5-8mm to allow for expansion of the wood.
2. Begin to screw your deck boards to the joists. You’ll need to secure the deck board to every joist is covers along your deck frame. Use two screws for every joist. Mark where you’re going to add your screws, ensuring that they are at least 15mm from the end of the board and 20mm from the outside edges. Drill pilot holes for the screws, being careful to only drill through the deck board and not the joist. Then screw the decking screws into the holes.
3. Continue to screw in the deck boards, ensuring you leave the correct expansion gap. You can stagger the deck board joins across the deck for more strength.
4. Sand down any cut ends if you need to before applying decking preserver to protect the timber from rotting.

Garden slabs are a joy to behold but only when done the right way. Well, the installation of paving slabs shouldn’t be exceed digging a little here and there, buying a small amount of mortar and pressing down the garden slab, right? Absolutely not! But we must admit how great it would have been if only it were that easy in real life. Let’s be honest, in reality, laying garden slabs does not only require you to prepare your sub-base painstakingly and mix your mortar using the appropriate materials, but you’d also have to work with accurate and precise paver placements to guarantee the patio’s longevity. Consequently, this happens to be a stressful and quite tricky challenge. If you lack the required confidence to pull this off, we’d recommend you hire the services of a seasoned professional who can guarantee the best results and also save you time and extra cash that may result from possible costly errors. In this guide, you’d gain more insight into the garden slabs laying process.

To get started, you’ll need sharp sand, cement, shovel, wheelbarrow, pointing trowel, rubber mallet, spirit level, jointing compound, hard-bristled brush and tarpaulin.

1. Mix a layer of mortar for each paver.
2. Apply the mixed mortar onto the sub base by using the trowel.
3. Slot the first flag in place and ensure not to stain the paver’s surface with the mixed mortar.
4. Using a rubber mallet, carefully tap the paver to the mortar bed. Once done, ensure the surface is even with a spirit level.
5. Take a measurement of the gap between the pavers
6. Repeat the above steps until all pavers have been perfectly laid
7. Leave the pavers to dry for about 1 to 2 days. You can protect it using a tarpaulin if concerned about rain.
8. Use the jointing compound to fill up the paver gaps to bind together the pavers. Ensure to wipe off any excess compound using the hard-bristled brush.

Driveways usually sink because they haven’t been laid properly. They may not have been dug deep enough, or the installer might not have used the right materials. This will need to be corrected at the earliest opportunity, although in extreme cases, the driveway may need to be completly be relaid.

Different types of gardening work will need to be carried out at different times of the year. Garden maintenance is a year round job, although the amount of work will usually decrease during the winter. For larger landscaping projects, aim to have these done through autumn, winter and early spring, to give plants time to get established before summer. Be aware that poor weather over winter can slow down the work.

1. Place a post in the corner of the frame you created with the pegs and string. Measure and mark out 100mm from each side.
2. Dig out this soil to a depth of 700mm (watch out for cables or pipes). You should have a 300 x 300mm hole. Repeat for the other 3 corners.
3. Using a brick bolster, split a concrete block in two. Put a section of the block in each hole.
4. Get a length of post longer than you need and place one in each hole. You can cut it down later.
5. Create props on each post to hold them in place until you’re ready to add a cement mix. Check that they’re level. When you’re happy that they are, secure them in place with a concrete mix, making sure you create a slope in the concrete so that rainwater runs away from each post. When the concrete is set, remove the props.
6. Create a string line around each corner post and find the centre point between each. Place a timber batten at each point, ensuring that they’re not spaced any more than 1500mm apart.

1. Working from the corner where the deck will be at its highest above ground level, measure and mark on the post where the highest part of the frame will be.
2. Measure from the far side of one post to the opposite and cut sections of joist to size. Line up a piece of joist with the mark you made and temporarily secure it. Factor in a 2mm fall for every metre of decking so rainwater can run off.
3. Secure the frame to the other corner post, ensuring it’s at the right level. Do this for every side of the outer frame.
4. Using 100mm coach screws with washers hanging on the end, secure each end of the four sections of frame.
5. Mark out where the centre of the support posts will be and secure all of these posts to the frame, except the centre post.
6. Add your central support joists. These should run in the same direction as the deck boards will run. You’ll need to measure from the inside of the frame on one side to the inside of the frame on the opposite side. Attach the joist in the same way as you did for the other posts. Repeat so the centre post is in between two sections of frame and secure the posts with concrete.
7. Trim down all the posts to the correct height using a saw.
8. Add your weed-control fabric and weigh down with gravel across the entire area.

1. Measure 400mm from the centre of the outer frame and mark a line. This will be where the first joist is positioned. Repeat at 400mm intervals down the length of the frame – if the last one will be more than 400mm, add another joist to create enough support.
2. Attach a joist hanger to each end of the joist.
3. Place the joist in position so the centre lines up with the 400mm spacer mark.
4. Secure using external grade screws once you’re happy that the joist is flush with the frame.

Uneven lawn? Well, for an outdoor space which looks great and serves its purpose throughout the year, there’s a need to learn how to level your garden. While its best left for a professional to handle, there are also some simple steps you can follow to ensure your DIY task turns out a success whether you’re preparing to lay a patio or deck, landscaping the whole space or tackling a lumpy lawn. A level ground comes with a bunch of benefits which includes maximizing the functions of your yard, helping with drainage while also enhancing your property’s curb appeal. Good news is, you can level your sloping lawn by hand. Want to know how? In this post, we’re going to take you through the processes involved in levelling an uneven lawn. Let’s take a look!

You can simply level your lawn using your hand if you aim to make your lawn a more even surface or to install a patio or deck. If your goal is only to make the lawn more even, you should have it in mind that, even though lumps and bumps aren’t always pleasing for most people, it can actually create a good drainage for your home.

Top dressing is the solution for depressions that are about 2cm to 3cm deep. To resolve this, simply get a top dressing mixture or make yours using two parts of sand and topsoil and a single part of compost. Use this to fill out the depression evenly and make compact using a rake or your feet, then water. Leave this for two days before applying grass seed alongside a thin layer of topsoil, then water as needed.

If you have a deeper depression, simply dig out to around 4cm to 5cm and remove any lumps of soil or stones. Once done, proceed to top dressing as explained above and grass seed to fill out the bald spot.
