Cinder blocks? Sometimes called pumice blocks but pumice is too light and wimpy. Lightly crushed volcanic cinder (foamy reddish lava rock) mixed with cement to stick it together. It's the styrofoam version of concrete. Not for load bearing structural use, except for holding itself up, at which it tends to excel poorly. Likes to crumble in earthquakes. Absolutely not suitable for use as jack stands. Should be filled solid with concrete and rebar if you insist upon building a structure with these blocks that you want to be reasonably certain it will stay upright. Would likely make a heck of a mess, but if you could flood the cavities in the blocks with sodium silicate then let that dry after it drains out, followed by painting a coat of urethane resin on the inside of the wall, that might seal the blocks to keep the water on the out side. I'd finish the job by pumping the cavities full of low expanding urethane foam. Sodium silicate was pumped into a cracked wall and surrounding soil at a leaking radioactive fuel storage pool at the Fukushima nuclear power plant, stopped the leak, might work on your basement. Might even strengthen the blocks and prevent unintended basement living in the event of an earthquake. --- This email has been checked for viruses by Avast antivirus software. http://www.avast.com ------------------------------------------------------------------------------ BPM Camp - Free Virtual Workshop May 6th at 10am PDT/1PM EDT Develop your own process in accordance with the BPMN 2 standard Learn Process modeling best practices with Bonita BPM through live exercises http://www.bonitasoft.com/be-part-of-it/events/bpm-camp-virtual- event?utm_ source=Sourceforge_BPM_Camp_5_6_15&utm_medium=email&utm_campaign=VA_SF _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
