FAQAC: Frequently asked questions about concrete

A solid, well-made concrete foundation can make all the difference for your custom designed barn, shed or garage's life span. You can't just get a mixing truck, pour a load of concrete on your site and call it a day. There is a certain artistry to this part of the construction process, and you could say our Shed Boss builders are the master artists.

Here are some facts you should know about your concrete slab.

What size will my slab need to be?

The size of a slab required for your project very much depends on the specifications you outline when you design your own shed. In general, we will pour around 100 millimetres of concrete per 25 megapascals (MPa being the term used when measuring compressive strength of a foundation).

Will my soil type affect the concrete?

Yes, it's possible that the type of soil you have on your property will affect the specifications of your concrete slab. Soil classification (SC) is one of the first things we'll work out when preparing for laying the foundation, alongside the intended use of the building and its class under the National Construction Code. SC is how we judge your ground's reactivity, or in other words, how it will change in volume based on its likely swell and shrinkage rates.

How do I pour my slab to meet my COLORBOND warranty requirements?

If you opt for our complete project service, we'll do all the hard work for you, and that includes ensuring your product meets the specifications of your COLORBOND® warranty agreement. Many shed builders will erect your walls first, then pour a slab in afterwards. This process can do more harm than good, however, as it can cause premature corrosion. 

To meet the warranty, we'll lay your foundation first, then put up four enclosing walls to meet BlueScope Steel's specifications.

Your local Shed Boss team will be able to walk you through the rest of the finicky details, so make sure you give them a call if you have further questions.
