Our project has around 10 levels of undergrouns parking. A huge ramp for earth-movement vehicles is being created as construction evolves.
The slopes at the sides of the ramp go for more than 40 feet tall so it is a little bit difficult to put something like a plastic or a not-woven geotextile, the contractor sprayed concrete for the first 10 feet and then for the rest a mixture of cement and water (in Mexico is some sort of grout) is poured over the rest of the slope. As excavation goes deeper this mixture is poured over the new slope.
This mixture contains no additive, like I mentioned is only cement and water.
I just wanted to make sure that this is not considered some sort of soil contamination.

Michael, although I am not, as someone who is not a civil engineer, in the position to comment as an expert on this approach, my common-sense answer is that it sounds reasonable and not like soil contamination.I will also note that I have not heard of LEED reviewers getting really nit-picky about speciic ESC strategies under this credit. LEED seems to defer to your civil engineer.

Thank you Tristan, we also thought no soil contamination is present when you put only cement mixed with wáter (otherwise any slab on ground when demolished would be considered contaminated soil or contaminated debris, it makes no sense).
Thank you for your comments, we really apreciate it.

Hi Michael. I am in the same case, the foundation company says they plan to stabilize with a concrete spray to avoid damage to the ramp. How did it went in your LEED review process? Thanks!
