Hi everyone, I’m after advice on the correct steps for the following desired outcome. We are converting half of our garage into an internal room. The current concrete floor is uneven, slopes into the middle of itself probably by about 100mm from the sides. Not sure on dampness but the garage is single skin currently on two sides. The garage floor is also roughly 250mm lower than the house we want to level it with. Question I need help with is: Are these the correct steps to take to complete the floor before carpeting? DPM SLC (to even the existing floor) Insulation boards (150mm Celotex or similar brand) SLC or Screed poured directly over the boards Carpet underlay I am in no way experienced with this but the above is what I’ve cobbled together from other posts online, so looking for confirmation on those steps and any advice if I’m way out. Thanks everyone!
