Interested in reactivity with poured-in-place concrete. Is acid / sulfite a problem? Also would like to know if shallow foundation performance has been documented in reddog soil deposites. Some technologies that seem useful would be Soil Mixing (SM), dynamic compaction or Deep compaction grouting (auger cast piles). I am aware of slide issues and slope stability. I am not as informed about bearing capacity performance, shear strength, or the compactability of this material. Limestone has a reassonable affect on cleaning streams and it would seem a quarries limestone dust might be useful in neutralizing to some degree a soils reactivity. Subsurface grouting could easily deliver beneficial chemicals to deeper deposites. Other nutrients could be tilled into the top to develop a root structure or horizon. As for consolidation, a sheepsfoot rollers with dynamic compaction capability could pretty much collapse any near surface voids in the shale as well as change the physical structure of the deposits. How does it hold up to frost depth? Sorry about the ear. Are you aware of any methods of in-place stabilization for fairly level reddog beds, six to eight feet deep.
