How does volumetric readymix on-site batching work?
Our truck holds raw cement, sand, stone aggregate, and water in separate bins. On arrival at your site, our onboard computerized mixer batches your chosen BS 8500 readymix grade in real-time. You only pay for what is poured.
What readymix strength do I need for my extension?
Most single and double-story extensions in Harrow require C25 / FND 2 readymix concrete for trench fill footings. For internal floor slabs, C20 / GEN 3 is standard. Check structural engineer specs prior to ordering.
How long do I have to lay and finish the readymix concrete?
Because our readymix concrete is mixed fresh on site, you get full working time of approximately 1.5 to 2 hours depending on ambient weather temperature.
What if I order too much or too little readymix?
With volumetric batching, over-ordering penalties don't exist! We stop mixing the moment your slab is full. If your trench is deeper than planned, we simply mix extra m³ on the spot.
