Works connected with the patching of holes in the asphalt surface mean the correction of defects that occurred as a result of improper use of the road surface.
A big or small hole in the asphalt may be a result of using a low-quality material or ignoring the technological requirements for the production and laying of asphalt. Despite this, the holes are patched. The main thing is to know what material to use and when to do it. Usually, for these purposes, liquid asphalt or cold asphalt is used.
How to patch a hole in an asphalt road?
Potholes and other damage to asphalt pavement can often be repaired with cold asphalt filler. Below you will find a guide to help you successfully repair your road.
- Measure or estimate the amount of aggregate you will need to make the repair. Small potholes that are less than 0.2 square meters can be patched with about 20 pounds of cold asphalt aggregate.
- Choose the asphalt aggregate you will use for the repair. Cold asphalt aggregate (a mixture of asphalt resin and stones) is sold in 20-kg plastic bags, similar to cement bags, and also, in buckets of 4 to 20 liters.
- Clean the pit of lumps of dirt and other debris with a garden spatula, shovel, or other handy tools. If the bottom of the pit consists of dry soil, you should moisten it with a garden hose because tar only grabs on wet soil.
- If there is water in the pit, let it dry out because the resin won’t adhere to wet soil either. If you are in a hurry, you can use a fan or a hair dryer.
- Pits deeper than 7-10 cm should be filled with a material that can then be tamped down tightly, such as clay, broken concrete, or crushed limestone. For repair projects where the substrate under the patching cannot be tamped by conventional methods, it is recommended that the hole be fully excavated and filled with concrete 5 cm below the final road level – this will strengthen the problem area.
- Fill the hole with asphalt filler about one and a half centimeters above the final level of the road. This way, after tamping, the patch will be flush with the rest of the road surface.
- Compact the patch with a hand rammer or gasoline vibratory plate. Make sure that the cold filler is well tamped into the hole or the patch will quickly break apart when heavy traffic moves through it.
- If possible, cover the patch. To strengthen the patch even more, you can cover it for a couple of days with a board or a piece of plywood, but you don’t have to. If you have tamped the filler well, the patch is ready to be trafficked.
- Put away the tools and excess material left around the patch so you can admire your work.
Which liquid asphalt to choose?
Pay attention to the curing time of the asphalt and the consumption of the material, as well as what surface you can cover with liquid asphalt.

Tips for repairing a hole
- It is more convenient to use a vibratory plate to repair pits larger than 0.2 square meters.
- The resin washes off with a good mechanical hand cleaner. Be careful with solvents like white spirit, lubricants of any kind, and other chemicals as they can be harmful to your skin.
- If you want, you can dig under the asphalt surface around the pothole and fill that space with filler so that the patching material will reinforce and support the edges of the pothole weakened by the original accident.
- Big patching tends to sag a bit after cars start driving over it, so don’t be afraid to fill the middle of the pothole a half-inch higher. Car traffic will flatten the patching flush with the rest of the pavement over time.
The presence of a pothole in the asphalt of any nature negatively affects the movement of people and vehicles. Over time, the newly formed hole can enlarge and make the asphalt pavement unsuitable for movement. Consumers should understand the complexity of the problem before thinking about how to fix the hole in the asphalt. Different sizes of holes require different approaches to fixing them.
In exceptional cases, the hole can be filled with gravel. In such situations, the problem will be solved for a month at most. The long-term solution involves the use of innovative materials such as liquid asphalt.
What to seal the hole in the asphalt?
In the range of the store, you can find all the necessary materials. Their use guarantees the reliability and strength of the coating, and durability of operation regardless of changes in temperature regimes. Deciding to patch cracks and small holes, you should pay attention to the means Gorilla Waterproof Patch, thanks to which the work will be economically profitable. Choosing this material, consumers can cope with the repair by their own efforts. The help of professionals will not be required.
How to patch potholes with liquid asphalt with your own hands?
During repairs, you will need to use a tar gun, trowels and spatulas, brushes, gloves, knives, tamping, and sealing tools. The following materials will also be needed: asphalt in rolls and asphalt that is created by cold technology. They are sold in construction stores in the quantities that customers need.
Patching potholes with an asphalt mixture is the easiest way to remove minor damage from the roadway. A distinction is made between cold and hot asphalt. The first can be found in the construction store, and the second – is only to order at asphalt plants. In any case, the pothole must first be cleaned, removing debris and dust from it.
The edges of the pothole should not crumble intensely. The technology with the use of hot asphalt is simple. To do this, the entire hole must be filled with an asphalt mixture. She can also seal the hollows formed near the curbs.
If the pothole appeared in the middle of the road, you will need to deepen it, and pour the mixture so that it protruded two to three centimeters above the surface. After a few minutes, this layer should be leveled and tamped. To do this, you can use not only a roller but also a special vibropress.
With the help of cold asphalt can also be put in order potholes and holes formed in the yard. Under the cold asphalt, we understand the usual asphalt with the addition of some chemical components. The pothole must be cleaned of debris and dust. Applying a hammer and chisel, it is necessary in her to align the edges.
Cold asphalt should be put so that there was a small hill. Laying of asphalt is necessary to produce in two stages – to fill in a hole up to half and tightly tamped, then fill in again and the top part. On top of the poured cold asphalt, it is necessary to apply a layer of sand. Then you need to slowly drive the car over the hill. This way the asphalt is quickly compacted.
Other methods are used when along with potholes, there are cracks in the. In these cases, the pouring of tar is carried out. The surface is cleaned with a stiff brush or a special vacuum cleaner. The crack is immediately filled with tar, or covered with a few centimeters of sand, and then – with tar. Special guns are used for it. After fifteen to twenty minutes, the treated surface should be smoothed and pressed with a trowel.
There are also inexpensive rolls of ready-made asphalt. They are very convenient for repair work with a small volume. To do this, unwind the roll, remove the protective layer, and lay the asphalt adhesive side on the road. Then firmly press for a few seconds. This is the end of the repair.
Concrete pavements are used in a variety of applications: flooring installation, concreting surfaces in both industrial and residential sites, highway construction, and much more. However, concrete has a low tensile strength, so in the process of hardening the mixture shrinks a little, and shrinkage of structures occurs.
Because of this, small and more serious defects appear on the surface. In this case, concrete crack sealing is required, which is carried out using different techniques depending on the type of damage and the cause of its appearance.
How to fix cracks in asphalt driveway?
- You need to clean the crack of dirt, pour hot bitumen into it, fill it with asphalt and go over it with a vibratory plate. But this is in good condition.
- The second option – is to buy a ready mix – Cold asphalt. It is created especially for patching potholes, but it will be expensive to fill large potholes.
Therefore, if need to make a budget, then rightly written above – the waste, their asphalt, and seal. You can press it with your feet, or with thicker layers with a vibratory plate.

What are the types of cracks in the concrete?
Some beginners or unscrupulous builders prefer to simply putty a hole or any other defect with putty or mortar. However, before you caulk a hole or crack in the concrete wall and other bases, it is worth understanding what exactly caused the appearance of such troubles.
Defects come in several types:
- Surface. Such cracks often appear after pouring the foundation in the process of drying sand-cement mortar, if the mixture was prepared without observing the required proportions of components, low-quality components were used or there was not enough water in the mixture.
- Shrinkage (also called hairline cracks). Defects of this type are considered the most dangerous because they occur not only in the deformation of the foundation but also in the entire structure as a whole. This leads to a decrease in strength. Defects of this type appear with an uneven load on the foundation and with an improper selection of the cement composition.
- Temperature-shrinkage. Cracks of this type appear in the process of hardening concrete foundations due to the exothermic reaction occurring between cement and water. Very often during the construction of walls and slabs, novice builders do not take into account the freedom of deformation, due to which there is temperature stress in the concrete mass and defects appear on the surface.
- Cracks and holes appear due to poor-quality reinforcement. If the framework to strengthen the structure is too weak, then it will sag under the loads, which will also lead to the formation of defects. In addition, reinforcing rods can begin to oxidize. Because of the appearance of corrosion, the material will increase in size, tearing the concrete mass from the inside.
Outdoor concrete surfaces are also susceptible to cracking. The external environment contains chemically active substances that create a favorable breeding ground for defects.
In addition, the destructive effect is caused by sharp temperature fluctuations, which can occur both on the surface and in the thickness of the concrete itself. In this case, the deleterious effect has not only the cold air but also the ultraviolet.
It is also worth paying attention to the width of cracks, as in some cases such defects are not critical.
Before you start caulking, you should check the crack itself for chipping around it. If there are any, they may turn into holes in the near future, so it is imperative to eliminate all flaking pieces of concrete. After that, it is necessary to:
Perform a reaming. To do this, using a chisel and hammer, you need to go over the entire length of the crack so that its depth is at least 5 mm. If necessary, you can use a trowel to create a recess.
- Remove the dust with a vacuum cleaner and rinse the depression with water.
- Remove the excess water and fill the crack with cement mortar (3 parts sand to 1 part of cement with the addition of PVA).
- Make sure that the cement covers the entire area of the hole.
- Dampen the poured cement with water.
Caulking the hole
If a hole is formed in the concrete surface, in which you can see the armature, the defect can be sealed as follows:
- Clean the hole in the concrete and treat its surface with an anti-corrosion composition.
- Lay into the recess pieces of steel wire diameter of about 4 mm.
- After this, the recess is mashed priming composition, evenly applying it to the entire surface. In this case, the thickness of the layer of the mixture should be about 3 mm.
- Do not wait until the mixture dries, fill the hole with a cement composition for sealing cracks in concrete and make sure it fills the entire hole. If the hole is too deep, the cement is poured in several steps. At the same time, each subsequent layer should be wet with water from a sprayer.
- Elevate the surface with a lath (metal or wood), moving the tool from right to left.
- After the mixture has cured, remove the excess cement mixture with a trowel and plaster the surface. If the crack was too deep, then the leveling is performed with a grinder.
Useful! Cement composition should be poured with a reserve so that it is slightly higher than the surface of the floor. In the process of hardening, the mixture will give shrinkage.
After 24 hours, the concrete floor can be painted or any finishing material can be laid on it.
However, it is worth bearing in mind that such curing of cracks in the concrete will not give the effect of sealing and is not suitable for surfaces with high requirements for waterproofing. In addition, the cement composition can be considered as a temporary solution to the problems. Sooner or later the defects will appear again. If you want to “permanently” patch holes and avoid them in the future, in this case, you can seal up the defects with resins, specialized repair compositions based on them, or sealant.
Deciding what to seal cracks in concrete for the long term, you should pay attention to this method of processing defects. Resin and caulking mixes based on it are suitable for the restoration of screeds, backings and various concreted areas or horizontal surfaces.
Repairing cracks in concrete using such compositions has a number of advantages. First of all, it is the cheapness of the mixtures, as well as their quick drying time. On the other hand, the resin allows you to reliably fix the joints and keep them from further enlargement.
So, to eliminate defects, you will need to prepare:
- An angle grinder and diamond-coated discs
- Vacuum cleaner
- Trowels and a trough for diluting the composition;
- Concrete primer
- Epoxy resin
- Fine sifted sand
Before you seal the crack, you need to clean it of dust and dirt.
After that, perform caulking in the following sequence:
- Perform the expansion of the crack. In this case, the width of the resulting recess must be at least 5 mm.
- With the grinder cut transverse joints in the concrete at intervals of 400 mm (length of grooves about 100-150 mm).
- Remove a loose layer of concrete and dedust the surface with a vacuum cleaner.
- Treat the surface of the defect with a primer, and fix transverse grooves with repair staples.
- Prepare a solution of resin (base), hardener and sand, according to the instructions on the packaging of the composition.
- We fill the defect with the obtained mixture and quickly level the surface, as the setting time of the resin is only 10 minutes.
