Save Money & Avoid Problems by Choosing the Right Concrete Strength for Your Job. This page explains the C-class designations, which are used for the majority of jobs and explains how to choose the best concrete grade for your job.

Garden Paths and Patios

A garden path or patio is classed as light foot traffic. A C20 concrete grade is a good grade for this type of work. It is strong enough to resist surface wear but isn’t over-engineered for the low-load area of a garden path or patio.

Driveways

C25 is suitable for use on driveways as it will withstand the weight of cars and repeated use without cracking or pulling apart.

Shed or Garage Base

A garage base carries the weight of the structure plus any vehicles parked inside the garage, hence C25 is the correct grade for a garage base.

Strip Foundations

Strip Foundation – C30 minimum for Domestic Structure. The structural load will compress the concrete. The aim is to create a solid base that will not crack under the weight of the building above.

Getting the Grade Wrong

This means that under-specifying the concrete will result in surface cracking and early wear. Conversely, over-specifying the concrete will result in unnecessary expenditure for no extra benefit in relation to the job in hand.

Confirm Before You Order

Confirm Before You Order – Once you’ve chosen a suitable concrete grade for your project, discuss your requirements with your chosen supplier before ordering. If you want Concrete Swindon, https://www.monstermixconcrete.co.uk/concrete-swindon/ is a good place to start.
