Concrete may seem simple at first, and on smaller scale projects it can be. However, when it comes to managing the sidewalks in front of your business it’s important to get the right poundage and be knowledgeable on all the options you have. The first topic that should be discussed when it comes to concrete is the pounds per square inch (PSI). PSI essentially determines the strength of the concrete and can be changed depending on the ratio of concrete, water, and aggregate. The typical PSI range is between 2500 – 5000 each with their own benefits.
- 2500: A more affordable option although not as strong, can be used for driveways and walkways but usually a higher psi is chosen to reduce cracking.
- 3000: Useful for residential projects or anywhere that does not receive a lot of traffic. The heavier weight will help protect it against the weather
- 3500: This is less common with residential work and used more for slab foundations and footings. It can also be used when expecting heavier loads are expected.
- 4000: Usually used in warehouses and factories as they are expecting heavier loads and machinery. This can also be used for residential purposes if planning on building a workshops or sheds due to the strength and durability.
- 5000: This is used for special cases in construction of large scale industrial and commercial properties. Useful for it’s extreme durability and with standing heavy impacts.
