Who is Sun Silicates?

Gerbrand Haasbroek - Group Managing Director

Founded in 2006 by Gerbrand Haasbroek, Sun Silicates (Pty) Ltd is owned and managed by a dynamic team of engineers and chemical specialists. As a self-professed entrepreneur, it had been a lifelong desire of Gerbrand to develop business opportunities and after extensive local and international experience in the metallurgical and chemical industry, he decided to start his first industrial scale venture.

Initially an opportunity was identified for   the manufacture of Potassium Silicates for the welding and agricultural industries.

A furnace was designed and built on a heavy-industrial site in Wadeville, east of Johannesburg and the first Potassium Silicate cullet was manufactured in 2010.

In 2012, a Perlite exfoliation plant was added. Since the technology and the products are complementary, a Vermiculite expansion facility was added in 2014 making Sun Silicates the only company in southern Africa with the capability to manufacture complete range of exfoliated Perlite and Vermiculite products. In 2014,  Gerbrand and his son Dewald also invested in Matutu Milling, an Attapulgite operation that supplies a variety of absorbent minerals. The plant was subsequently expanded and a new drier and milling facility is in the process of being constructed.

In 2017, a new, high capacity blending plant was added to the portfolio. This enables the Sun Silicates group of companies to manufacture sophisticated, pre-blended Perlite- and cement-based plasters and screeds, growing media, insulating and other refractory concretes as well as gunning mixes for fire protection.

CemteQ specialises in developing and marketing unique, value-adding solutions for the building and construction industries. Many of these opportunities are not new to the international building and construction sector but have not been fully explored in the South African or African context. Through our sister company, Sun Silicates, we have access to high quality Perlite production and use this as an aggregate replacement or partial replacement together with cement and special admixtures to produce unique and bespoke solutions for plaster, screeds and concrete applications. The end result is products which have significant insulation, fire-resistance, lightweight and acoustic properties.

Perlite in construction

Perlite is widely used in construction in the middle east, Europe and the USA. It’s low density and relatively low price make it ideal for use in eco-friendly mixtures with cementitious materials. Typical applications include:

  • Lightweight and insulating plasters
  • Insulating screeds on concrete floors or flat roofs
  • Lightweight and insulating concrete
  • Loose fill in cavities for insulation
  • Fireproofing of structural steel columns
  • Lightweight precast cladding
  • Decorative applications
