There was a sewage collapse near our house and the back flow caused water come out of the manhole. The waste water under the suspended floor through the air bricks. The sewage company cleaned & disinfected all the outside and but there is some sewer water under the floor. I dont have access to the gap. House is a mix of wooden and solid floor. What is the best way to get it cleaned without ripping all the floor apart? Appreciate any tips.
