How To Fix Driveway Cracks For GoodBy admin
Monday, 9 September 2019
Laying a new driveway is not something that a homeowner takes lightly. It can be an expensive investment, it can cause disruption and it can take a long time to find the best person to carry out the work.
So, if you discover that after just a few short weeks, your brand new driveway is starting to crack, you will be very disappointed. But don’t despair, there are a number of ways that you can fix cracks and improve the way that your driveway looks.
Better still, if you are reading this before you have replaced your driveway, you can choose a resin bound driveway and avoid cracks in the first place.
What Causes Driveway Cracks and How To Fix Driveway Cracks?
The causes of driveway cracks are almost always down to the way it has been laid. A good driveway is dependent on the condition of the base onto which it has been laid.
In most cases the base needs to be dug down to a suitable depth, a layer of stone added for drainage, a layer of sand added for stability and then, in some cases, an asphalt layer to provide an even and flat surface to work with.
If any of these steps go wrong, the finished surface can be uneven or prone to water damage – leaving it much more likely to crack.
The material that is used on your driveway can also be a contributing factor. Asphalt is known for being more likely to crack and crumble and concrete driveways are usually laid in sections and if an expansion gap is not left between the sections, it can also crack.
In some cases, it simply comes down to the mix of materials. Too liquid or too dry for the local weather conditions can result in cracks as the material starts to dry out.
Small hairline cracks that may seem acceptable can also become much worse due to how water behaves when it enters the crack. The water will sit in the crack and freezes in cold weather. This expands the crack making it much worse and in need of repair.
Finally, driveways that have not been laid to a suitable depth can be prone to cracking. The driveway needs to have enough strength to withstand heavy vehicles driving over it day after day. The depth of material needs to be suitable for how it is going to be used.
As you can see, there are so many variables when it comes to cracks in your driveway that choosing the right contractor who understands the local conditions and the way your driveway will be used is essential. But if you already have cracks – here’s how best to deal with them.
For larger cracks and holes, you will need to use the same asphalt material that was used for the entire driveway. If the hole or crack is deep, you can use pea gravel to fill it and then tamp it down so it is a strong surface for the layer of asphalt
Repairing Cracks In An Asphalt Driveway: The Process
● The first step in repairing cracks in an asphalt driveway is to ensure that the crack is cleaned out. This involves chiselling out any loose material around the edges of the crack, and using a wire brush to ensure the entire area is completely clean. You don’t want any loose material, or the patch won’t adhere to the surface.
● You can find a specialist sealant or filler at your D.I.Y store and this is the best way to fix small cracks. The filler is simply added to the crack using a filler gun, and then smoothed around the edges using a putty knife.
● For larger cracks and holes, you will need to use the same asphalt material that was used for the entire driveway. If the hole or crack is deep, you can use pea gravel to fill it and then tamp it down so it is a strong surface for the layer of asphalt. You should feather the edges to ensure it blends nicely with the surrounding area, but you may find that it still looks like a patch, even after a few weeks.
Unfortunately, you can get cracks in most driveways, and if they are serious, they are indicating an underlying problem that needs to be fixed before dealing with the superficial crack that you can see
Repairing Cracks In A Concrete Driveway: 3 Top Tips
● Once again, the first step is to clean the crack. This means removing any loose material, removing any weeds or moss, and ensuring it is completely clean, and ready for bonding with the filler.
● You can use a concrete filler or sealant to repair the crack if it is relatively small. This is simply added to the crack using a filler gun, before being smoothed over, and left to dry. The result may be that the crack still shows, but no longer causes a problem.
● You can use a driveway sealant over the entire driveway if you find that you are getting regular small or hairline cracks. This will prevent water getting into the cracks, freezing, and, consequently, causing them to expand.
Other Types Of Cracks To Consider
Unfortunately, you can get cracks in most driveways, and if they are serious, they are indicating an underlying problem that needs to be fixed before dealing with the superficial crack that you can see.
This may mean that the entire driveway will need to be lifted and relaid – with a more suitable base and drainage system.
In some cases, just sections of the driveway may require this treatment, but if you don’t deal with the issues beneath the driveway, cracks will continue to show.
Driveways that have cracks really do spoil the look and feel of their front of your home, and can be a huge disappointment for you as a homeowner!
Resin Bound Driveways: A Consistently Crack-Free Choice
A resin bound driveway is a mixture of aggregate and resin that has been combined and then trowelled onto a well-prepared sub-base. These driveways are known for being especially stable, and highly unlikely to crack. There are several reasons for this, including the following:
● A resin bound driveway is made from a flexible material that can withstand a certain amount of movement – more than aconcrete driveway can.
● The preparation of the base is the most important part of the process of laying a resin bound driveway. It involves stones for drainage, and an asphalt layer for a smooth surface.
● Resin bound driveways are permeable, so water will simply seep through the surface of the driveway, preventing pooling and puddles. This means that the material is not affected by water or ice, and will therefore remain undamaged.
● Resin bound driveways are laid in one continuous section. There are no joins of any kind and it is laid in one day with the entire driveway drying in the same time period. This means there are no joins that could lead to cracking.
● Resin bound driveways are laid to a depth of around 20cm depending on how it will be used. This depth makes it very strong and suitable for heavy cars. It is unlikely to crumble or crack due to the weight and everyday use.
You may have never considered resin bound driveways as a good alternative to the standard driveway materials available these days, but the lack of issues regarding cracking are a great reason to seriously consider this option.
As with any driveway, it is essential that you choose a contractor who understands the product and will lay it correctly. Always look for an experienced company and choose a contractor who can show you examples of their work.
Driveways that have cracks really do spoil the look and feel of their front of your home, and can be a huge disappointment for you as a homeowner.
