How thin can you pour concrete over concrete? Your new layer needs to be at least 2 inches thick. If it’s any thinner than that, it’ll easily crack under pressure and won’t adequately bond to your surface.
How Thin Can You Pour Concrete Over Concrete?
Concrete is one of the most popular and versatile materials used in construction today. It is strong, durable, and easy to work with, making it an ideal choice for many projects.
But when pouring concrete, there is a limit to how thin the layer of concrete can be. When pouring concrete over existing concrete, the thickness of the layer of concrete should not be less than two inches.
This is important because concrete layer that is too thin will not provide enough strength and support to hold up the surface that it is covering. If the concrete layer is too thin, it will crack and fail over time.
For concrete projects that require a thinner layer of concrete, you may be able to use a self–leveling compound. Self–leveling compounds are designed to be used in thin layers and are often used for interior concrete projects.
However, these compounds are not recommended for exterior concrete projects because they can be easily damaged by water and other elements.
If you are pouring concrete over existing concrete, you may need to use a mixture of concrete and sand. This mixture is often referred to as a “sand mix” and it is used to fill in gaps and irregularities in the existing concrete. The sand mix should not be less than two
