So we've had a lot of rain recently and I went out to my back yard to find our retaining wall has about 4 stones that have fallen out of it. I can't find an accurate photo of what is it, but it's pretty much a plain cement wall decorated in slabs of stone that have been pressed into the cement.What did the old owner do wrong to cause this? I assume water is getting in gaps of the stone and cement and freezing, pushing them out.Whats an easy way to put them back in?Short of redoing the whole wall, is there a "proper" way to refit them to prevent it from happening again?Thanks. via /r/DIY http://ift.tt/2lAsgZS
