Concrete is a durable and long-lasting material that many homeowners use for home improvement projects. However, it has varying strengths, and you’ll need to choose the proper pounds per square inch (PSI) for the best results. Here’s what to know about PSI and how to make the right choice for your project.

Why Is PSI Important?

PSI is used to determine how much pressure hardened concrete can take before breaking. The higher the PSI, the stronger the mixture. 

The PSI is calculated by looking at the ratio of the concrete’s composition, which includes water, cement, and aggregate. Generally, a lower water-to-cement ratio results in a stronger material.

What Are the Different Levels of PSI?

PSI scores range from 2,500 to 5,000. Concrete with a 2,500 PSI is the most affordable option and is typically used for driveways and walkways. However, some homeowners may choose a product with a 3,000 PSI if these surfaces have a lot of foot or vehicle traffic. 3,000 PSI is also often used for larger projects, like patios, because it can withstand freezing temperatures better.

When building the foundation of a home, a product with at least a 3,500 PSI is necessary to handle the weight of the structure and the contents inside it. Contractors will need to use a 4,000 to 5,000 PSI mixture for roads and bridges that must support heavy traffic.
