Hi, I made mention of this situation in another category in the site but it is more likely suited to be posted here.
Also of notable interest I was a Project Manager working with a roadside reinforcement operation about 6 years ago we were stabilizing a road which was built atop a old wash pond from a sand and gravel operation in the late 1900's on the side of a mountain Northern Pennsylvania near NewJersey, we were Drilling on a slope adjacent to the area that fell; the entire road pretty much sank into the mountain side thus blowing out the toe of the slope 20' down the embankment from where the road originally started elevation wise (I know your thinking what the hell does this have to do with the conversation... let me finish as details are of importance to what we saw at this particularsite) so the solution was to drive 1441 steel casing 8" od × 0.750" wall in at 4' spacing along the road hillside x 40' deep [2] 20's welded together with 0.125" 1018 arc rod. The casing minimum reveal was 6" from the surface after being driven to refusal. We welded 1" x 8' x 6' plates to these casings so that 2 casings were fastened to each plate after 4 of these units were assembled we started having issues with the drills particularly on the computer controller side and had to switch from remote control to manual to continue there is 1600' of these assemblies installed at this location next we used a grout pump to inject each case via atremmi tube to force the grout from the bottom to the top under pressure to form a lollipop on the end of the case. Next we connected the plates together with fiberglass rebar and a ground ring zinc coated copper 0.50"dia was embedded in the area around the plates. Following the installation of the grounding ring is where things got weird, we poured the containment wall atop the fiberglass cage and ground ring the concrete was a special mix that contained #300 mesh Aluminum powder to react with the lime and generate hydrogen gas I believe which in turn caused the concrete to heat up and foam up similar to spray foam this was an intentional response what was weird was the following day when we went down to strip the forms off, anything that was made of iron/steel had vibrated when placed onto the foam concrete structure and where the joints exist below thepoor is a stranger phenomenon yet when you place a aluminum/brass wrench atop at these joint locations the wrench vibrates and turns slowly back and forth as though someone isturning it on the surface... Naturally I tried other experiments while I was there too. Next there was a class triple A super A cap pouredon top to protect the superlight retaining wall below and cast into this section is a epoxy coated steel rear cage with guide rail platesattached. And also the road was eventually finished with many unforeseen events and issues alike. With the cap in place the strange magnetic fields seemed to subside atop the structure however other oddities arose.
