Did You Know?
1. In ancient Rome, holes and cracks in concrete floors were often filled with a mixture called “opus signinum,” which consisted of crushed tiles mixed with lime and volcanic ash. This mixture created a durable and waterproof solution.
2. One creative method that can be used to fill small holes in a concrete floor is by using a mixture called “slurry” composed of cement, water, and fine sand. This slurry is poured into the hole, and the excess is wiped away, resulting in a smooth surface.
3. Did you know that holes in concrete floors can sometimes be caused by a natural process called “concrete spalling?” This occurs when water penetrates the concrete, freezes, and expands, leading to cracks and holes over time.
4. For larger holes in concrete floors, a common technique called “trowel-grade mortar” can be used. This mortar is a special mix designed specifically for patching holes and can be applied with a trowel to achieve a level and even surface.
5. If you prefer a more convenient solution, there are now pre-packaged concrete-filled epoxy products available on the market. These products consist of a two-part system where the epoxy is mixed with a hardening agent. When applied, it hardens to fill the hole and provide a durable fix.
Three Methods Attempted (Only Two Used)
When it comes to filling holes in a concrete floor, there are various methods that can be attempted. In this guide, we will discuss three methods, highlighting two that are commonly used for the actual repair process. Each method can be effective in its own way, and the choice between them will depend on the size and severity of the hole.
The first method involves using an angle grinder with a concrete cutting disc. This method is best suited for smaller holes or cracks that need to be filled. The angle grinder helps to remove any loose or damaged concrete around the hole, creating a clean surface for the repair. Once the area is prepared, new concrete can be applied to fill the hole.
The second method utilizes a hammer and chisel. This is a more manual approach and can be used for both small and larger holes. The hammer and chisel are used to break away any loose or damaged concrete around the hole, creating a clean and stable area for the repair. However, this method may require more effort and time compared to using an angle grinder.
The third method, which will not be used in the actual repair process, involves using a wooden board or sheet metal to cover the hole temporarily. This method can be useful for situations where immediate repair is not possible, such as during extreme weather conditions or when professional assistance is required. However, it is important to note that this method is only a temporary solution and should not be considered a permanent fix.

Process Of Filling Holes In Concrete Floors
The process of filling holes in concrete floors involves several steps to ensure a successful and long-lasting repair.
Firstly, using the chosen method (angle grinder or hammer and chisel), the damaged area around the hole should be carefully removed. This will create a clean surface and ensure that the new concrete adheres properly.
Once the area is prepared, the hole should be thoroughly cleaned to remove any debris or loose particles. This can be done using a brush or vacuum.
Before applying the new concrete, it is important to moisten the hole with water. This will prevent the existing concrete from absorbing the moisture from the new concrete, leading to a weaker bond.
The next step is to mix the concrete according to the manufacturer’s instructions. The mixed concrete should have a consistency similar to a thick pancake batter.
With the mixed concrete ready, it can now be poured into the hole. It is important to fill the hole completely, ensuring that no air gaps are left. A trowel or a flat board can be used to level the surface of the new concrete.
After filling the hole, the concrete should be left to cure according to the manufacturer’s instructions. This usually involves keeping the area moist for a specific period to allow the concrete to harden properly.
- Use chosen method (angle grinder or hammer and chisel) to carefully remove the damaged area around the hole.
- Thoroughly clean the hole using a brush or vacuum to remove any debris or loose particles.
- Moisten the hole with water before applying the new concrete to prevent weaker bonding.
- Mix the concrete according to the manufacturer’s instructions, achieving a consistency similar to a thick pancake batter.
- Pour the mixed concrete into the hole, ensuring complete filling and no air gaps.
- Use a trowel or flat board to level the surface of the new concrete.

Causes Of Concrete Floor Holes
Concrete floors can develop holes due to various causes, and understanding these causes is essential for preventing future damage. One common cause is ground torsion, which refers to the twisting or movement of the ground beneath the concrete slab. This movement can lead to stress and cracks in the concrete, eventually resulting in larger holes.
Another cause of concrete floor holes is improper installation or poor quality of the concrete itself. If the concrete is not mixed correctly, has inadequate reinforcement, or is not properly cured, it can be more susceptible to cracking and developing holes.
In some cases, heavy or sharp objects dropped onto the concrete floor can also cause holes. For example, dropping a tool or a heavy object from a height onto the floor can create impact damage and result in a hole.
Repairing Concrete Floor Holes By Re-Applying Concrete
Repairing concrete floor holes involves re-applying concrete to the damaged area after proper preparation. This method ensures a seamless and long-lasting repair.
By removing any loose or damaged concrete around the hole using either an angle grinder or a hammer and chisel, a stable surface is created. This preparation is crucial to ensure that the new concrete adheres properly and forms a strong bond.
Once the hole is prepared, the new concrete can be mixed according to the manufacturer’s instructions. The mixed concrete should be poured into the hole, completely filling it and leaving no air gaps. Leveling the surface of the new concrete using a trowel or flat board will ensure a smooth and even finish.
After the new concrete is applied, it is important to allow it to cure properly. This usually involves keeping the area moist and following the manufacturer’s instructions for curing time. Curing is crucial for the concrete to harden fully and achieve its maximum strength.

Importance Of Chiseling Before Filling With New Concrete
Chiseling the hole before filling it with new concrete is a vital step in the repair process. This preparation ensures that the new concrete adheres properly and forms a strong bond with the existing concrete.
By chiseling the hole, any loose or damaged concrete is removed, creating a clean and stable surface. This surface allows the new concrete to fuse with the existing concrete, forming a seamless repair.
Chiseling also helps to create a rough texture on the edges of the hole, providing more surface area for the new concrete to bond to. This increases the strength and durability of the repair.
Neglecting to chisel the hole properly before filling it with new concrete can result in a weaker bond and a subpar repair. Therefore, taking the time and effort to chisel the hole is crucial for a sound and long-lasting repair.
- Chiseling the hole removes loose or damaged concrete
- Creates a clean and stable surface
- Allows new concrete to fuse with existing concrete
- Rough texture on edges increases strength and durability
