Concrete is one of the strongest and rigid materials you can use to build constructions and buildings. It can last for quite a long time and provides reliable durability.
But like any other material, it has its disadvantages. However, compared to wood or steel, concrete is tons better. And here we will tell you why:
When timber starts rotting, there’s nothing to be done, it merely has to be replaced. It’s the same scenario with steel. When corrosion hits, besides replacement, nothing else can be done.
But things have a different look when it comes down to the concrete. If cracks happen to appear, fortunately, the concrete doesn’t have to be replaced. You can repair those cracks with concrete crack fillers.
Cracks can occur due to a large number of events. For example, one of the most common cases is because of temperature fluctuations.
As you probably know, hot weather causes materials to extend, and cold weather to shrink. That’s viable for concrete too.
And if the concrete surface doesn’t have the proper water-cement ratio, this leads to cracks and holes.
And concrete cracks and breaks are fixed with crack repair kits. And what do they do?
- Crack fillers are used slowly and gently when filling the cracks in concrete
- Crack repair kit will prevent smaller holes from growing and becoming more prominent. This way you’ll keep the reliable construction of your house
- They will deter insects from populating small cracks by filling them
That’s why it crucial to repair and patch the cracks in concrete. You can put your mind at ease, knowing that you are going to get your hands on a high-quality and effective concrete patch.

Types Of Concrete Crack Fillers
There are 5 types of concrete crack fillers you need to be aware of to buy the best concrete patch depending on your personal occasion.
Concrete Crack Sealant
This type of concrete patch repair is meant to be used only for thin cracks and holes, up to a half-inch. The thing you need to be aware of here is that it’s only suitable for horizontal surfaces. Otherwise, it won’t create a steady and robust repair.
Concrete Repair Caulk
This one is typically applied using a caulk gun. It’s suitable for narrower cracks up to a half-inch. The advantage here is that it can be used for both vertical and horizontal holes.
Quick-Setting Cement
Further down the line, we stumble on a quick-setting concrete crack filler which is primarily used for cracks from a half-inch up to 1 inch.
In odd cases, the quick-setting cement has to be mixed with a bonding liquid to slow down the curing process so the filler can have enough time to strengthen the concrete slabs.
Hydraulic Cement
As the name suggests, this type of crack filler is mainly utilised upon cracks that feature leaks.
Patching Compound
Usually, patching compounds are primarily used upon shoal cracks. They are available in both pre-mix and dry cement powder. On the whole, they add incredible strength and durability to the slab.
Things To Consider Before Buying Concrete Crack Filler
Crack Width
The first and foremost is the crack breadth. You need to be highly aware of the size of the hole you are trying to repair.
Skipping that will result in buying a crack filler which isn’t suitable for your situation. Therefore you’ll have to spend more money on the proper crack patch.
Curing Time
You need to look for a balanced time here. Too fast, or slow will harm the robustness of the concrete slab. Depending on formulation and usage, you’ll have several options to choose from.
Easy To Use
This is a crucial feature that adds incredibly to the buying decision. If you buy a sophisticated concrete crack filler that you aren’t familiar with, you’ll have trouble using it. Strive for pre-mixed crack fillers.
Temperature Tolerance
We are all familiar with the contractions and extensions that happen to any material due to hot and cold weather.
That’s why make sure the concrete crack filler is flexible enough to sustain any contractions or extensions caused by unfavourable weather.
