Concrete Grades

Concrete grade is defined as the minimum compressive strength rating of a mix 28 days after it was poured. Different construction projects will require concrete of certain strength ratings, so understanding the difference between concrete grades is key to finding the ideal mix for your specific requirements.

At Total Concrete, we supply a comprehensive range of concrete mixes across Surrey, Hampshire, Berkshire, Middlesex and some London postcodes, covering all manner of construction applications. Below, we’ve highlighted just some of the different concrete grades we supply, alongside their strength ratings and their recommended uses. Our concrete plant can, however, produce just about every type of concrete grade, so please get in touch for more information.
