Limestone layer
Limestone layer
(OP)
Hey all, I am a structural engineer. Recently I came across a geotechnical report where the elevation of limestone layer varies about 13 ft between two boring 150 ft apart. Is it normal? I would like to hear from other geotech engineers on this forum before I raise the question to our project geotech engineer. The project is located in Dallas Texas, and there is a small creek about 400 ft away from the borings.
(I didn't want to complicate the question. But there are other borings clustering around the two borings in question. In each "cluster", their elevation variations are within 5 ft.)

RE: Limestone layer
if the small creak has incised through limestone during geologic time (and the incision infilled by alluvium) it's very likely.
if the limestone is prone to solutioning, it's very likely.
fortunatly there are no prior ice sheets/glaciers that made it down to Texas!
