Concrete cube testing is a simple, cost effective test of the compressive strength of concrete, providing you peace of mind that your concrete is fit for purpose. Concrete samples are taken from the concrete truck while being poured and are then cast and air cured under BS standard conditions. Samples are then water cured for specific periods of time at spot on labratory then crushed to determine its maximum compressive strength.

Concrete cube testing is the main compliance test for concrete and is also a requirement of BSI kite marking. Cubes come in mainly two sizes: 100mm and 150mm. 100mm are more common for continuous testing and are more easily storable. Cube testing is now a common operation for all concrete suppliers; not only does it tell you if your concrete is fit for purpose but with enough information it can help alter mixes which will save you money.


At Spot on Concrete we specialise in concrete cube testing at a very competitive price. We also offer a unique service which means that our Technicians will not solely test the concrete on site and leave. Technicians will also offer further assistance where needed, all at no extra cost eg. pushing a wheel barrow, offering technical assistance, e

Volumetric concrete mixers are a state of the art truck that carry all raw materials on them (see diagrams). The mixers have the benefit of mixing onsite so if someone has ordered a wrong mix or needs to alter the mix this is no longer a problem. The Volumetric truck mixer is becoming increasingly more popular in the construction world as they can travel further and hold more.



Our ready mix concrete gives us precise control over how much concrete is made for your project. So, how much do you need? The bulk of your concrete will probably be going into a square area, so you calculate how much concrete you need with a few measurements:

When calculating the amount of concrete required, we recommend adding an extra 5-10% onto your total estimate to allow for possible errors as well as spillage or over excavation / uneven surfaces.
