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."
