An extra level of caution is needed if you are repairing a pothole on a private road that vehicles are likely to use during your fix. If this is the case, you may be best to contact a local pothole repair contractor to be on the err on the side of caution.

Contractors are available for such jobs too. So if you have any doubt, hire a professional. Search for local pothole repair or tarmac surfacing contractors. If the repair job is for a road, you may want to consider hiring a contractor with a Street Works Qualifications Register (SWQR) ID card.

Potholes are formed when cracks develop on the surface of a road due to the tarmac heating up during the day and cooling overnight. Rainwater enters these cracks and, when the temperature drops below freezing, the water will freeze and expand, causing the cracks to swell. With added stress from vehicle traffic, potholes develop and will gradually widen.

However much you enjoy DIY, the less time spent filling up gaps in your driveway means more time on valuable other jobs. We only ever recommend the permanent method of filling potholes to fix them for good so you won’t be doing the same job again when next winter arrives.

Potholes on public roads and main carriageways can be a huge safety risk to drivers, cyclists and pedestrians. And that’s not even mentioning the damage they can cause to vehicles (RAC estimates point to one-third of UK cars suffering damage due to potholes).

If you notice a pothole on a public road, including an A road or motorway, that poses a danger to traffic, please report it immediately to either your local council or the Highways Agency.

If you are filling potholes during wet weather, use Permanent Pothole Repair Wet. This specially formulated product can easily handle heavy showers without risking the product’s overall quality.

Like with most jobs, successful pothole repairs are all about the preparation. Cold-lay tarmacs cure almost immediately, so the hole will need to be fully cleared of debris and prepped before you take the quick-to-cure tarmac out of the bag.

Once applied, the cold-lay tarmac will set almost immediately. It can take pedestrian traffic straight away and can withstand vehicle traffic within moments. It’s that easy!

Consider whether you ever spotted a pothole that had popped out. And have you noticed potholes failing and needing filling again, sometimes within the space of a few months?

If you’re a contractor working on a public road, highway or a private job for a carpark, you’ll need a larger size of aggregate in the cold-lay tarmac to ensure the material can withstand the stress from heavy traffic. Skid resistance is also an important factor. Our review of cold-lay tarmacs for public roads and heavy traffic will be coming soon.

If you’re not skilled with tools or are not physically strong enough for hard work, don’t attempt to fill a pothole by yourself. Hire a contractor, especially for larger projects as heavy equipment is often required.

In conclusion, if you’re skilled with hand tools and have a strong back, here’s what you’ll need to fix a pothole: a brush and/or pointed trowel, a circular saw (preferably with a diamond blade), a bag or tub or cold-lay tarmac, a can of cold joint spray, a hand tamp, and bonding tape.

For example, for major carriageways and roads, a stronger, skid-resistant cold-lay tarmac is a must. Cold-lay tarmacs such as Tough Patch are recommended for filling potholes on roads that are heavily trafficked and require more skid-resistance.

As mentioned earlier, if you do spot a pothole on a public road or carriageway, contact either your local council or the Highways Agency to report it. There is a handy postcode look-up tool on the government’s website to find the right contact.

Patching asphalt yourself is not as simple as it sounds, so be sure to put safety first and wear gloves, goggles, and a mask if you don’t want your face burned by bitumen or dust particles.

If you have a larger pothole on your hands (of more than 100mm deep), it will be a much more extensive repair job. In these cases, we strongly recommend hiring a professional tarmac repair contractor to resurface the area.

Cold-lay tarmac is available in various sizes of aggregate to suit the depth of the pothole and the type of vehicle traffic that is likely in the area.

A pre-mixed pothole repair filler – otherwise known as cold-lay tarmac – is the main material you will need to fill and fix a pothole.

We recommend each layer being a maximum of 45mm deep and compacting it to 30mm. The fact you can easily lose 15mm with each layer after compacting demonstrates the necessity to layer and compact each time.

If you have potholes on a driveway, private road or pathway, and know how to safely use a circular saw, our tutorial above on fixing potholes takes you through what to do to fill and fix them permanently.

For domestic use – on driveways, paths and private roads – either Permanent Pothole Repair 3mm or Instant Road Repair 6mm will both do the job fine (see the advice below on which is best for surfaces withstanding vehicles). They are both HAPAS approved and can fill potholes of up to 100mm deep.

This tutorial is for filling potholes on asphalt or tarmac surfaces. Concrete paths would require way more work and proper equipment.

Choose Instant Road Repair Red if you have a red-tarmaced driveway or pathway. All other cold-lay tarmacs come in black.

Most potholes in driveways and private footpaths should be minor in size, so look for a product containing aggregate of between 3–6mm. Always check the product is HAPAS approved, which means it has passed the strict and rigorous independent testing measures as part of the Highways Authority Product Approval Scheme. It’s not just to do with safety, but it also means the product has proven its long-term durability so your pothole repair is long lasting, and ideally permanent.

Steels are heated to their appropriate hardening temperature {usually between 800-900°C), held at temperature, then "quenched" (rapidly cooled), often in oil or ...

Cold-lay tarmacs such as Instant Road Repair and Permanent Pothole Repair can be used in most types of weather except extreme weather. With these products, and most other cold-lay tarmacs, ensure the temperature will not drop below freezing during application or hit above 30°C. Extremely hot spells can soften the binder within the tarmac.

A much hardier and stronger formula must be used for heavily trafficked areas. Either Tough Patch or Permanent Pothole Repair Wet would be the best choice to prevent undue skids and accidents.

The good news is, with the right tools and materials, most people have the necessary skills for repairing a pothole themselves.

Layering gives you the opportunity to ensure each layer is fully compacted. What you are working towards is making sure there are no gaps or voids for water to creep into and that will cause your filling job to fail.

A sealant, such as cold joint bitumen spray, and bonding tape are two other essential materials for permanently fixing potholes. Many contractors are opting for Ultracrete SCJ spray for a reliable sealant and Ultracrete Instaband Eco for the over-banding tape.

With the tarmac still in its plastic bag, gently roll your knee against it to manipulate the material and make it malleable. Some added light pressure will help the tarmac return to its usual consistency.

Both Permanent Pothole Repair 3mm and Instant Road Repair 6mm are high-quality, fine-grade, HAPAS-approved tarmac pothole fillers that come in handy-sized, pre-mixed tubs or bags that are ready to pour into the pothole. Most potholes in driveways and private paths should be fairly shallow. These two pothole repair mixtures can be used up to fill potholes up to 100mm deep.

When using concrete as a pothole filler, it is challenging to get the exact amount of mixture needed. Too much and you have excessive concrete on your hands. Too little and you’re back to the drawing board to do another mix.

Although concrete would technically work for filling in a hole, using concrete is way more dangerous than mixing your asphalt because its temperature is about 100 degrees hotter, making it impossible to apply without risking severe burns on hands and feet.

For the best results with over-banding tape, use a blow torch to securely seal the tape around the pothole repair and prevent water ingress.

Another thing to keep your eye on is the rain. Cold-lay tarmacs can generally be applied during mild showers. However, heavy rain risks filling the pothole up with water, which reduces the quality of the cure and the overall standard of the fill.

Always wear gloves when touching anything abrasive like sandpaper, stone, bitumen, or any other material that could leave your skin red with a rash or painful chemical burns.

Cold-lay tarmac and pothole repair fillers do not adhere properly to rough, unprepared edges. With an added cold joint spray sealant, such as Ultracrete SCJ, your pothole fix will be a professional and long-lasting job.

For the best results, apply layers of tarmac, fully compacting each layer and applying a cold joint spray before adding each extra layer.

For permanent pothole repairs you’ll need a few extra tools and materials to properly prepare the hole and seal the pothole filler in place:

Over-banding tape such as Instaband Eco is a thermoplastic tape that helps to prevent water seeping around the new pothole. This is especially important if you do not have a petrol plate compactor or wacker plate to fully compact the uncured tarmac.

When fixing potholes, there are still some people who simply clear the hole of debris and fill it with cold-lay tarmac before tamping it down.

Watch the video to see the process of filling a pothole in action. Please note, this process involves using a petrol-powered wacker plate, but a hand tamp is fine for smaller jobs. We just recommend applying an overbanding tape to ensure there is no water ingress.

Most professional contractors opt for premixed cold-lay asphalt, even on larger pothole repair jobs. Ready-to-pour asphalt, like Ultracrete’s Instant Road Repair, takes away the extra hassle of mixing and offers a water-tight repair job every time.

Hiring a plate compactor or wacker plate can make the compacting process much easier (and will put less stress on your back from compacting with a hand tool), so consider hiring one if you have a few potholes to fill. Essentially, when you use a plate compactor the fill is likely to have no voids at all.

Read our handy guide on how to fix a pothole on your driveway, private path, tarmac patio area or private road. Permanent pothole repairs is what it’s all about (let’s avoid having to fill them again next year!). We take you through the tools you need, which tarmac fillers are most suitable and how to get started.

Best practice is to avoid heavy showers during application as this will fill up the pothole with standing water, often to the detriment of the tarmac formula.

A pothole is a depression in the surface of a road, path or carpark where the tar has worn away. It will typically cause damage to tyres on vehicles and bicycles. They can also affect a car’s wheel alignment, suspension and framework.

Generally speaking, most domestic potholes will be much smaller than the size of potholes that can develop on our public roads and carriageways.

You can attempt to mix-up a batch of asphalt yourself, but it might not be the right consistency. You would need a road roller to mix it properly, which is not an option if you’re only fixing the pothole by hand. Plus, if you use too much bitumen or filler, your patch will end up being weaker than any pothole that was there before.

The permanent way to fix a pothole is by using a circular saw, ideally with a diamond blade, to cut a neat, vertical-edged shape around the pothole itself. What you’re left with is a rigid picture frame with straight, flush edges.

Choosing the right filler for the job is essential. Things you should consider when choosing the best cold-lay tarmac for the job are:

Most bitumen and asphalt is made of black tarmac, however red-coloured tarmac is available too. Luckily the team at Ultracrete have formulated a red pothole repair material to mend any holes in red tarmac driveways.
