Questions about concrete, aggregates and delivery?
How much ready-mix concrete do I need?
The amount depends on the length, width and depth of the area being filled. St. Mary’s volumetric concrete is mixed on site, so you only pay for the concrete you actually use rather than having to estimate an exact load in advance.
Do you supply small quantities of concrete?
Yes. We supply everyone from contractors and tradespeople to DIY customers, and there are no part-load charges with our volumetric concrete service.
Where do you deliver?
We deliver ready-mix concrete, decorative gravel, aggregates and building supplies across Cornwall and into Devon. Contact us with your postcode or delivery location and we can confirm availability.
Can you help if access to my site is difficult?
Yes. We can advise on delivery and concrete placement options, including concrete pumping where direct access for the vehicle is difficult.
