Bosun

What Bosun does

Bosun is a South African manufacturer of concrete paving bricks, kerbs, and retaining wall blocks, founded in 1993 and headquartered in Midrand, Gauteng. The company operates three manufacturing facilities in Midrand (Gauteng), Brits (North West), and Port Elizabeth (Eastern Cape), using advanced German-engineered (HESS Group) dry cast concrete equipment with on-site testing laboratories that validate SANS 1058:2012 compliance for every production batch. Its product portfolio spans paving (Designer, Regular, Interlocking, Flagstone, Permeable, Tactile), kerbs, retaining wall blocks (including the proprietary Versoblock system), and pool coping, with proprietary finishes such as Colourfast® (permanent fade-resistant colour) and Organic (exposed aggregate). Bosun holds CMHA and CMACS certifications and a five-year product guarantee.

The company operates a sales-led go-to-market, selling direct to homeowners, contractors, architects, and engineers through three factory showrooms, online request-a-quote forms, and technical consultation services. It also distributes through retailers such as Cashbuild and via sister companies SmartStone (wet cast paving) and Cretesol (jointing products and German Probst handling equipment), creating an integrated ecosystem. Pricing is unit-based per square metre, ranging from R110-R180 for standard 50mm grey pavers up to R40-R150 premiums for advanced finishes (Colourfast, Organic, Stone, Polished), with separate R1200-R5700 transport charges within 125km reflecting the heavy, crane-offloaded nature of the product. Reference projects include Gautrain stations, Nelson Mandela Children's Hospital, Alice Lane, and Jewel City, alongside thousands of residential installations. The company is privately owned (legal entity Bosun Brick (Midrand) (Pty) LTD), with no external investment, no M&A activity, and no public revenue disclosure.
