New Septic tank has crack in floor
Just got this 1,000 gallon fibered cement installed last fall. Last week I finally filled it up with water-The contractor had never done a leak test so this is the first time water has ever touched the tank.. Well, upon filling up with water, I guess some sediment got washed around and I noticed there was a crack going almost all the way across the floor. Hadn’t noticed it before. Judging by these pictures can you tell if this is just a surface crack or if something that I should try to get fixed. How would you even fix this? 😞
