Hi All, I hope you are well. I have about 90 years old house. I was trying to asses if the concrete has a membrane but I reckon I would need to drill to find out. I have taken pictures of the ducting hole, I see some plastic sticking out but not sure if you can consider this a moisture barrier...

Hi, I'm coming to the point where I will actually need to get some concrete in. I like the idea of volumetric concrete so that I pay for what I use. I need about 1.2 cubic metres of concrete and will have to barrow it. Having phoned a few people up there seems to be a big difference in price...
