Concrete can be used as a substrate for which of the following?

Concrete serves as a versatile substrate that is suitable for a variety of flooring types. In particular, it accommodates carpet, ceramic tiles, and linoleum.

Starting with carpet installations, concrete provides a solid base that can support the weight of the carpet and its padding. It is important for the underlayment to be prepared properly to create a smooth, level surface for optimal adhesion and performance.

Ceramic tiles also require a stable, rigid substrate, and concrete meets this need effectively. The strength and durability of concrete help to ensure that the tiles are less likely to crack over time, as long as the substrate is adequately prepared and cured.

Linoleum, similar to carpet, can also be installed directly onto a concrete substrate, provided that the surface is clean, dry, and level. Linoleum’s flexibility allows it to conform to the underlying surface, making concrete an appropriate base material.

While wood flooring installations can technically be done over concrete, it typically requires an additional underlayment or moisture barrier to prevent the wood from absorbing moisture from the concrete, which can lead to warping or mold issues. Therefore, concrete is better recognized as a straightforward substrate for carpet, ceramic tiles, and linoleum, rather than as a direct base for wood flooring.
