FAQs

Find answers to common questions below, or visit our Knowledge Hub for more concrete technical information. 

What is the recommended waste allowance when calculating concrete volumes?

Even the most perfect pour will waste some concrete. To ensure you have enough concrete for your project, we recommend adding 5-10% to the calculated volume. This will account for waste from spillages, uneven surfaces, and other factors.

How to prepare for a concrete pour

It doesn’t matter how big or small your concrete pour is, the first step is to prepare the ground. This involves excavating to the required depth: for strip footings this is generally to undisturbed ground, while for pad foundations and floor slabs you will need to allow enough depth for your sub base and damp-proof membrane (dpm) as well as the concrete.

How to lay a concrete base

Follow this step-by-step guide for all you need to know about laying a concrete slab. Steps include preparing the ground, how to frame the slab area, how much concrete is needed, pouring the concrete and curing the concrete afterwards for a perfect result. Read more.
