1 Zero weathering: lasts 50–100 years without powdering (Interlock: spalls after 5–10 years).
2 Truly fireproof: survives bush fires (Interlock: collapses above 500°C).
3 Unaffected by prolonged flooding/rainy seasons (Interlock: softens and erodes).
4 Immune to salt corrosion in coastal/arid areas (Interlock: cement slowly destroyed).
5 Lifetime stable strength (Interlock: loses 20–40% strength in 10 years).
Conclusion: In Africa, for a house that lasts generations, fired red brick is still king.
