hometips.gregvan.com Well you’ve seen the cut concrete floor slab in the other video, now it’s time to see what it actually looks like before the plumbing pipes are installed. Make sure that you don’t remove any more dirt than absolutely necessary, because you need to read compacted or purchase additional fill. Removing as little dirt as possible will save you money and time. If you’re going to use fill, any dirt that you remove will need to be hauled off in this means that you will be spending more money in waste disposal fees and you will also need more fill, to fill the holes, before you pour the concrete.
