About Us

LOUNGE Cape Town-min

Committed to Smart,
Sustainable Building

CemteQ strives to offer the highest quality, most consistent lightweight building materials, products and systems on the market at competitive pricing. We develop and produce innovative sustainable materials and products and actively seek to repurpose waste materials with suitable properties into green buildings.

Our products are significantly lighter than conventional materials which provides the inherent benefits of excellent thermal efficiency and a low embodied energy. We focus on re-engineering materials that are waste or bi-products of other industries and also ensure end-of-life recyclability.

We offer high quality exfoliated perlite products and blends which are used as an aggregate in composite cementitious formulations to produce unique and bespoke lightweight, insulating solutions for the building industry.

Sustainability and innovation have always been at the heart of our business and have led us to combine cement, designer admixtures and post-industrial recycled polystyrene, plastics and other waste products that otherwise end up in landfills as input materials into our sustainable lightweight composite concrete products.
