It does work, I have used this on a number or ocasions. You need to be careful with how bad the floor is and how much you put in. If you put a small blob on a scrap piece of wood you will see how much it expands as it cures. If you use too much you will run the risk of the floor going the other way and leaving a lump in the floor instead of a dip. I do use some dowels just for added strength but leave every other hole open for the foam to expand. Removal is quite easy once dried with an old wood saw and scraper. Also leave as long as possible to aid the curing process. As with the 2 pack support and tape the floor from underneath, and I use a scaffold board and some weight inside (gas bottles battery bricks etc)

Hi. I used this type of product without problems. Just drilled the holes 100mm apart on a grid pattern and squirted it in with a big hypodermic syringe. No dowels used. I left mine for a week to cure (it was cold at the time). Went over the section of floor with a scraper followed by the belt sander. Floor now solid and a very happy PJH10.
