We produce quality aggregates from the natural Malmesbury Hornfels deposits in our quarry. The cubical shape of our stone, which is important role in producing quality concrete, is very important to us.

At Portland we provide a range of concretes designed for the entire spectrum of the construction industry. These products are backed by our expertise and tight quality control guaranteeing strength and durability.

Portland manufactures and installs precast hollow core slabs with state-of-art technology from Elematic in Finland. We provide a complete service, from design to manufacture and installation.

AMAZING MILESTONES

Nico Heyns and Helenus Scholtz founded Portland Builders in 1988. Focussing mainly on the residential market, they established a solid business and continued this for the next 12 years.
1988
At the turn of the century, Portland Builders acquired a 65 Hectare quarry with Malmesbury Horrfels deposits just beyond the beautiful Durbanville winelands.  Soon after the acquisition, the quarry underwent a major facelift and new offices were built, a decent entrance road was scraped and new crushers were also installed.
2000
In 2001, Portland Group yet again expanded their business by installing three readymix concrete plants on the site and acquiring a fleet of readymix trucks to deliver the concrete.
2001
In 2008 we further expanded our operations to the manufacture and installation of precast Hollow core slabs.  We acquired state-of-the-art technology from Elematic in Finland to make sure we produce high quality slabs.
2008
Hollowcore factory underwent a face lift and added 4 extra lanes among with new Weller technology from Germany. The stockyard was extended to the outside of the factory, more than doubling the capacity of production.
2015
Portland has been doing business for the past 30 years and we are not only still going strong, but we are growing as well. Here's to the next 30!
2018
Towards the end of 2019, the opportunity presented itself for Portland to become involved in two new quarries along with Tip Trans Resources. In November 2019, Portland Aggregates was established with two new quarries, namely Portland Weskus Quarry (in Jacobsbay) and Portland Worcester Quarry (in Rawsonville),

WE BELIEVE IN

SUSTAINABILITY

We make the world we live in and we shape our own environment. Without environmental sustainability and economic stability, social cohesion cannot be achieved.

ENVIRONMENT

Portland’s primary Quarry situated in Durbanville, Cape Town is nestled between the Diep River and Tygerberg mountain range and surrounded by mostly farm land. The river forms the natural border of the north-western part of the Quarry, providing a bio-diverse ecosystem with an impressive variety of fauna and flora on its banks.

We care about the environment surrounding us and one of our key concerns is the deterioration of the water quality of the river system and the irreversible impact that could have on the various animal species, and also the people who depend on it.

We are continuously improving the ways in which we reduce water, air and ground pollution.

While our products are already ecologically friendly, we are in an ongoing process to improve this to ensure sustainable water, energy and other natural-resource savings for the future.

HEALTH & SAFETY

Health-and-safety

At Portland we believe that the effective control of risk and occupational illness is an integral part of business and we make every effort to identify any potential risks. Once identified, we focus on reducing, preventing and eliminating these risks so that no-one suffers any loss whatsoever.

Our people are what makes our business work, so personal accident prevention, training and efficient production go hand in hand. Every employee should be able to work in a safe, clean and healthy environment and we make sure that this is the norm.

Portland Quarry resides under the Mine Health and Safety Act and we use this Act to guide our Loss Control, Safety and Occupational Health program. Together with our employees we work to prevent injury, eliminate damage to equipment, reduce wastage of material and minimize business interruptions.

QUALITY

Quality

Portland values all stakeholders, not only our clients – although they are our top priority. To that end the company has implemented the ISO 9001:2015 Quality Management System in all our business units. We are proud to say that Portland Holdings has successfully maintained our certification status since the implementation in 2016.

The company’s main focus is the consistent quality of our products and services and the continuous improvement of client satisfaction. Our aim is to be the preferred supplier in the areas that we serve and certainly the number one supplier of aggregates, ready mix concrete and precast hollow core slabs in the Western Cape.

SOCIAL & ECONOMIC DEVELOPMENT

Portland Quarry’s Social & Labour Plan is focussed on uplifting the community around us through various initiatives. Our local economic development (LED) project benefits the Fisantekraal Centre for Development. We try to volunteer where we can and also frequently host trainees for “in job training”.

We also frequently contribute to Olympians Social Development & Education, a non-profit organisation that provides mentoring programs to youth and adults in the rural and sub-economic areas. OSDE’s goal is to foster a commitment to youth in these areas that will promote pro-social friendships, strong interpersonal skills and reassert a sense of hope for the future. The funds made at the annual Portland Charity Golf Challenge also benefit this organisation. FAW Cape Town acts as main sponsor for this event. In 2020 we even had Mr South Africa, Heinrich Gabler, join us for the event.
