Murray River Limestone was born from a shared passion for exceptional quality, aesthetically pleasing limestone blocks, and a genuine understanding of the landscaping and civil construction industries.
Jesse Chambers and Sam Rasheed are two passionate South Australian business owners who have spent years working across landscaping and civil construction. Ongoing supply challenges highlighted an opportunity to create a high-quality alternative using locally sourced limestone from our own region — and so, Murray River Limestone in Murray Bridge was born.
