Trusted by builders across the UK.
Real reviews from contractors, self-builders and developers who poured with Majors Mix.
"Specified Majors Mix for a basement waterproof pour. Their technical advisor walked our engineer through the additive spec on the phone. Pour went without a hitch and the finish was exceptional."
"Booked the screed pumping truck for three floors of UFH. Pumped to the second floor without breaking sweat. Lay was perfectly level — tilers came in two days later and said it was the flattest base they'd had all year."
"I run small, awkward jobs in zone 2 London. Majors Mix are the only supplier I trust to turn up with a small vehicle for restricted access. Their mix-on-site means zero waste — and the calculator means I never over-order."
"Used the calculator before booking — the volume estimate was bang on for our commercial slab. The crew turned up to the minute and the mix was perfect C32/40. We've moved three other framework jobs over to Majors Mix since."
"Calculator told me exactly how much I needed for my extension. Sent the result through WhatsApp and had a quote back in under 10 minutes. The volumetric truck meant we paid only for what we used. Refreshing."
"Big national suppliers can't compete on transparency. The on-page calculator saves my estimators hours. Switched a recent housing development to Majors Mix — quality matched, price was sharper, driver actually cared."
