We are audited every 6 months to confirm our exceptional high standards of concrete and customer service are being maintained. Our entire fleet of volumetric concrete mixers are calibrated every 6 weeks to ensure the concrete from spot on, is spot on!

Spot on Concrete also operate an in-house laboratory, and offer a full concrete testing service, our technicians will take a sample of your concrete delivery. This will be slump tested, and cube tested, we will then email you a report to show your clients the exceptional quality of the concrete ordered. See example below

Here are Spot on Concrete we do not use recycled aggregates or blended cement.

To ensure our concrete is the best concrete available, we only buy the best materials available, British standard 4-20mm limestone, 4-10mm limestone, washed 0-4mm gritsand and Opc CEM 1 cement 52.5N,

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, etc.

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.







At Spot on Concrete, we carry out calibrations of the volumetric mixers to make sure they comply, that the trucks are batching correctly and also to check that the vehicles are not over or under yielding as this could be costly. Volumetric calibrations are to be carried out every 6 weeks calibrating the:

– Cement

– Water

– Sand

– Gravel
