But below that you could use crushed concrete. <br /><br />Brick however, and concrete block for that matter, I would not use. Brick is much softer than concrete, and concrete block is also much more porous than poured concrete. I also have doubts that they will be able to crush this material to a small enough size on site. I would not want my house sitting on top of this stuff.lavarderahttps://www.blogger.com/profile/07241073948874188058noreply@blogger.comtag:blogger.com,1999:blog-38363189.post-27991980178450549792012-03-06T09:36:45.299-05:002012-03-06T09:36:45.299-05:00I am about to tear down my block and brick house a...I am about to tear down my block and brick house and my contractor wants to recycle the material on site in order to use it in place of crushed stone for the foundation and drainage. Your article has me thinking it would not be wise to use the crushed concrete for the foundatione. What about the brick? Or, what about using a lower layer of crushed concrete and the top two inches in crushed stone or brick for the foundation?Farfohttps://www.blogger.com/profile/10309730479711600950noreply@blogger.comtag:blogger.com,1999:blog-38363189.post-35102445003805171512010-07-04T23:38:19.818-04:002010-07-04T23:38:19.818-04:00As I recall, concrete can wick moisture using capi...As I recall, concrete can wick moisture using capillary action up to 10 stories in height.KMeadnoreply@blogger.comtag:blogger.com,1999:blog-38363189.post-77120871034932202602010-07-01T16:19:06.112-04:002010-07-01T16:19:06.112-04:00It actually would depend on what kind of stone the...It actually would depend on what kind of stone the crushed stone was made from. It can be limestone, or granite - depending on what is more common in your region. And within that the porosity of the stone coming out a given quarry at a given time can vary. But generally its not going to approach the porosity of concrete used for construction - which would later be crushed and sold as a stone substitute.lavarderahttps://www.blogger.com/profile/07241073948874188058noreply@blogger.comtag:blogger.com,1999:blog-38363189.post-9101379817473489262010-07-01T15:41:51.367-04:002010-07-01T15:41:51.367-04:00Isn't crushed rock also porous?Isn't crushed rock also porous?Anonymousnoreply@blogger.com
