Alfa concrete walls precast walling history

In 1978 a gentleman with the name Johan van Tonder started Alfa Concrete Walls. His precast walling company quickly grew from strength to strength. His first precast concrete walling company was situated in Garsfontein drive extension, Tygerpoort, on the eastern outskirts of Pretoria in Tshwane Metropolitan area.

He moved his Concrete precast manufacturing plant to Lynnwood Road Pretoria later on, where Alfa Concrete Walls can still be found up to today. Thus 2018 is the 40th birthday of Alfa concrete walls, this year and 40 years in the precast walling business.

In those days new walling installations was the main focus. Later, products like wall extensions and Concrete palisades came along.

Johan pioneered some of the early wall precast wall extension techniques. Wall extension techniques still used today. Concrete palisade inserts in standard precast walling was a another of his brain child’s.

After growing the precast walling company for many years, he became a forced to be reckoned with in the Pretoria, Kempton Park and Bronkhorstspruit areas.

At this point Johan had 8 concrete walling installation teams in the field. And supplied several smaller companies with wholesale precast wall panels and poles.

I met Johan in 1996, when he installed a precast wall for me. Little did I know what impacted Alfa Concrete Walls would have on my live later on. In 2005 I had the pleasure once again to meet Johan and his friendly precast walling staff when they installed a 800m x 2.4 meter high Precast wall in Pretoria for me. Sad to say Johan’s health had detracted a couple of years before and could not manage 8 teams any more. With no son to follow in his dad’s foot steps Johan decided it was time to retire.

Leon Willemse bought Alfa Concrete Walls from Johan in 2006. Leon new what the potential was, as he and Johan had a long-standing friendship. Johan gladly took Leon under his wing and transferred his wealth op precast walling knowledge. Alfa quickly grew again. From 17 Personnel to over a 100.
