A large share of what is sold as "local" building material in Dar es Salaam arrives finished, in a container, and gets a new bag before it reaches site. The buyer cannot tell where it was made, who made it, or what is actually inside.

We do not work that way. No finished blocks, no finished sealant, no finished profiles are imported for resale. If it carries our name, it was produced or finished at Kigamboni.

A bag with our name on it should be traceable to a line, a shift and a batch — not to a container number.

• Sand-based AAC blocks — quartz sand, lime, cement, autoclaved under pressure
• Masonry mortar — for block laying, thin-bed and conventional
• Plaster mortar — interior and exterior finishing coats
• Tile adhesive — floors and walls, interior and exterior
• Aluminium profiles — window, door and facade systems to 6063-T5/T6
• Silicone sealant — structural, weatherproof, glazing and interior
• MS modified-silane adhesive — low-odour, paintable bonding and sealing

The Chinese line on our paperwork reads 中华好品，荣耀非洲 — good products from China, glory in Africa. It is a promise about the standard of what leaves the plant, and about where the value should stay.

We read it the plain way: the quality has to be good enough to carry a Chinese manufacturing standard into an African project, and the benefit has to land here — in local jobs, local supply and buildings that do not need to be repaired in five years.

• Made here — production at Kigamboni, not re-export
• One standard — the same specification for a pallet and a container
• Traceable — batch and date on the pack
• Local — jobs, service and a phone number that answers
