I had Juan the owner of Diamond concrete come bid my new construction foundation floor
the floor was to be a exposed floor with no floor covering
after 3 days the floor had a crack from one end to the other end and 2 months later is has 6 major cracks across the floor
I had 2 other contractors come look at the cracking of my floor and they both told me that the cracking was due to substandard preparation work that Diamond concrete charged extra to do
