Nearly Four Decades Of Growth
Our Four Commitments
Environment
Our Durbanville quarry sits between the Diep River and the Tygerberg mountains, so how we manage water, air, and ground impact matters to the people and land around us, not just to a compliance checklist.
Health & Safety
We are committed to identifying and reducing risk to ensure no one experiences any loss. Portland Quarry operates under the Mine Health and Safety Act, guiding our Loss Control, Safety, and Occupational Health program for every employee.
Quality
We have run the ISO 9001:2015 Quality Management System across every business unit since 2016. It is the standard we hold ourselves to on every load of aggregate, every batch of readymix, and every hollowcore slab we cast.
Social & Economic Development
Portland Quarry's Social & Labour Plan supports the Fisantekraal Centre for Development and Olympians Social Development & Education, a non-profit offering mentoring programs for youth in rural and underprivileged areas.
