Portland Builders was founded in 1988 by Nico Heyns and Helenus Scholtz, partners for the past 24 years. Portland Group has since been transformed into one of the leading suppliers of aggregates, ready mix and hollow core in the Western Cape.
In 2000, Heyns and Scholtz had the opportunity to buy their 65ha quarry, situated on the picturesque Vissershok Road in Durbanville. Ever since, visitors and employees have been able to appreciate the view of the blooming canola each year.
Portland Quarry produces construction aggregates, primarily crushed stone and dust from the natural deposits of the Malmesbury Hornfels. In 2000 the quarry underwent a major facelift and new offices were built, a decent entrance road was scraped and new crushers were also installed.
After many years of crushing, Portland Quarry underwent another upgrade in 2014, replacing all underground cabling and computerizing the whole plant. Ensuring optimum production time and minimum break downs. The fully computerized control center, overlooks the whole plant, giving a great picture of what is happening at the plant.
