Hello
We are in the process of replacing a door in the basement where we needed to do some concreting. The previous door frame rested on a board approximately 70x8x3, and we filled this hole with some extra coarse concrete we had. Already 24 hours later it feels stable; can we start installing the interior door or should we wait? I understand that the risk of cracks is high if we don't water it, but in this case, it doesn't matter much.
