Dishonest Concrete suppliers, M200 was brought for the place of the M400 brand, the quality of concrete is terrible, the concrete cups that we poured are all crumbling, after gaining strength, on the thirtieth day, they sent their technologist with a Schmid hammer, the technologist confirmed that the concrete does not correspond to the M400 brand, the BlueBeton management claims that in a year it will gain strength, without responsible suppliers do not contact them, in construction chats, all builders bypass this supplier!!!
