• Dug out the area until you reach a suitable level

• Ensure that the proposed finish level is 150mm underneath the damp proof course in any of the adjoining building’s brick.

lEdge Restraints

• Build a 100mm depth-thick concrete foundation with the help of a concrete mixer, 1 part cement and 6 parts ballast.

• Position the kerb unit on top of the level with a string line and spirit level.

• Use a trowel and rubber mallet to mortar the kerb unit to the foundation.

• Haunch the back of the kerb units in such a way that the concrete reach half way up the kerb’s rear.

lSubbase

• Put the crushed concrete in the edge restraints and ensure it’s at the desired level of 50mm.

• Use a vibrating plate to compact and level

lScreeding

• Apply a layer of sharp sand (to 50mm depth) and campact it using a vibrating plate.

• Apply second layer of sharp sand (to 20mm depth) on top of the first layer.

• Level the second layer to the correct falls.

lInstallation Of Paving

• Lay the block paving starting from the bottom of a slope.

• Ensure the blocks are placed at about 10mm to 15mm above the required finish level.

• Make sure the blocks used are between 3-5 packs as you proceed with your desired pattern. You may need to cut smaller block pieces to fill smaller gaps.

lFinishing Touches

• Clear out the area to ensure no debris is left on the blocks.

• Put kiln dried sand and brush across the whole of the area, ensuring the sands falls between the blocks’ joints.

• Compact the drive with the vibrating plate.

• Brush more kiln dried sand over the area and compact again

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.

If you’re considering laying gravel on your driveway, then you’d probably want to know the amount of gravel you’ll need to complete the project. When you are calculating the amount of gravel you’ll require to cover your driveway, there’s an important factor you’ll need to consider and that is the type of gravel you opt for such as a crushed or pea gravel. There are varying grades which are found in particles from fine to course, with a size ranging from 2mm to 64mm. Therefore, there’s a need to estimate the volume of the gravel while also having the rock’s size in mind. Also, there’s a need to select your most preferred gravel which you’ll like to use before proceeding to dig the depth of your driveway and subsequently determine the amount of gravel that’ll be needed using these excellent tips.

✓ Determine the size and coverage. As you would have expected, the smaller the gravel is, the bigger the coverage will be, and gravels should be at least 4 inches deep. However, if the rocks happen to be a bit large then you can allow for an extra 1/2 inch.

✓ Measure the driveway. Multiply the width by the length and depth to get the size of the driveway in cubic feet. Meanwhile for cubic yards, you can divide the total cubic feet by 27. This is due to the fact that one cubic feet is same as 1.13 tons.

✓ Working with gravel. Here, you’ll have to calculate an underlay measurements differently. You can use 2 inches of road base that’ll be overlaid with 2 inches of gravel.

It’s up to you what size gravel you use for your driveway, but there are some guidelines that are worth following. If you go too small, your gravel will get displaced easily. But, if you go too big, you driveway might be quite tricky to walk on. Generally, it’s a good idea to go for a gravel size somewhere between 10-20mm.

Gravel is the cheapest driveway surfacing material. Asphalt costs a little more than gravel, and concrete is significantly more expensive. The cost of paving depends on the material you use. Obtain as many quotes as possible as materials and costs differ from company to company.

Creating a tarmac path or driveway is a tricky process. It’s a job best left to professionals who know what they’re doing, as there are plenty of opportunities for it go wrong. However, even if you’re planning to hire someone to do it for you, it’s worth knowing how it’s done.

Firstly, you’ll need to remove any existing path or driveway and excavate down to formation level – about 175mm below paving level. Then, a membrane is laid down to prevent weed growth.

Next, a sub-base goes down, usually made of crushed rock or concrete. This is compacted and the tarmac is laid over the top. This is put down in two layers, and is rolled to make it compact and smooth.

It’s important to use edging when laying tarmac, to ensure that it doesn’t run off where you want your path or driveway to be. Tarmac paving and driveways also needs suitable drainage.

Have you decided to install block paving and wondering what the best sand to be applied to the joints is in order to achieve a perfect job? Well, you’re at the right place! This is one of the most frequently asked questions when it comes to block paving and we seek to give you a reliable solution once and for all.

The best sand for block paving is a kiln-dried sand. It’s an extremely fine sand which has been dried in a kiln to get rid of all the water before it’s incorporated to achieve the best results. Therefore, the sand contains no moisture and is commonly used to fill the joints of block paving to keep the paving’s structure rigid and strong. It also goes a long way to prevent the ingress of water while stopping the paving from moving and becoming loose. The major reason why the paving sand must be dried is to allow it flow easily into the joints as well as the block paving’s gaps. As result of this smooth flowing to the bottom of the joints, there will be no sand sticking to the sides of the pavers.

Another major reason why kiln-dried sand is commonly applied to the block paving’s joints is to prevent water from penetrating the paved area. It also tightens the individual pavers together to prevent from moving and becoming loose. In the event whereby you happen to leave the joints of your block paving without kiln dried sand, it’s highly likely that they’ll sink as a result of water penetration and the blocks will become very loose. After washing block paving, it’s very important to also replace any sand washed off in the process once the paving is dried to prevent water ingress into the joints.
