Concrete is an excellent product for many construction applications. Cured concrete has excellent compression strength and is often used for floors and foundations. Concrete floors are incredibly durable. Unfortunately, the characteristics that make concrete such a popular choice in construction applications also make it very difficult to remove. Self-levelling concrete is no exception to this rule. Removing concrete is a physically demanding process that in most cases requires the complete destruction of the concrete structure.

Things you need
- Concrete saw
- Sledge hammer
- Ear protection
- Eye protection
- Dust mask
Put on the eye and ear protection and the dust mask. Use the concrete saw to cut the floor into sections of concrete that are small enough that they can be physically removed. The size of the sections will be dependent on the depth of the self-levelling concrete floor, with deeper floors requiring smaller sections. All cuts should be through the full depth of the concrete.
Use the sledge hammer to break free any sections that can not be freely removed from the floor. The sections may be adhered to the substrate beneath the concrete floor but since this typically would be loose gravel or crushed stone, the sections should break free after being struck with the sledge hammer. Sections along the perimeter of the concrete floor may be adhered to the walls or forms used to hold the concrete in place while it cured. Striking these sections with the sledge hammer should break them free.
Put on the gloves. Pick up and remove all of the sections of the self-levelling concrete floor.
Tips and warnings
- Another approach to removing the floor is to use a jackhammer to break the floor into small chunks. These jackhammers can be rented at large home maintenance stores where concrete saws also can be rented.
- Concrete can be recycled and that should certainly be considered for any large concrete removal projects.
- Determine what may be under your concrete floor before you begin to remove it. There is the potential for plumbing or electrical work to be located within the concrete or under it and there is a risk of cutting into or damaging either when removing the floor.
