The frequent building collapses in Lagos is because the building blocks industry is unregulated.
Every Tom Dick and Harry are making blocks however they want, nobody is regulating or monitoring what they mix and in what proportion they mix to mold blocks, which are being sold to builders.
Some of these block makers cut costs or use wrong cement or contaminated sand (too many impurities that reduce the quality of adhesion) or mold substandard blocks and that’s why you’re having building collapses all over. The Lagos State Government should as a matter of urgency implement regulations and monitoring to all block molders, so as to have uniformity of quality.
Many building blocks being sold today are substandard. Under 2 months, you can already see cracks in the surfaces of buildings. That’s why building collapses are now frequent in Nigeria not only particularly in Lagos.
