Go to the Maine Geological Survey digital Maps and look for what are called surficial materials Maps. Answer: I don't know the specifics of soil conditions in NOLA, but your question indicates that you think foundations need to reach bedrock. On the surface, the casing will be about 12 inches above the ground. Whereas parts of southern Arizona or Louisiana may have thousands of feet of unconsolidated surficial material overlying bedrock, the "depth to bedrock" in Maine is generally only a few tens of feet and rarely over a hundred. In Metairie and Kenner, just west of the city, a large building might need pilings up to 100 feet deep. There are some places, however, where a well can be more than 1,000 feet deep.

Given the large number of rivers that cross Louisiana, it is no wonder that so many of our soils are alluvial. Excellent electronic resources are available to help you understand the soils beneath your feet. The information provided here are intended for use in the synoptic study of large areas, and are likely not suitable for detailed study of geog. Soil properties across Louisiana vary considerably as well. Bedrock also underlies sand and other sediments on the ocean floor. Edit: I thought they had a well data search too, find a well nearby, click it and it should have overburden thickness. Even helpful geological "lingo" that maybe I am unaware of that would yield better results? Hello this is very informational video on how deep the bedrock is when you mine downwards as far as you can. as print on demand. Slightly acidic soils are ideal for the optimal availability of soil nutrients. The midcontinent crust is presumably sinking very slowly toward the Gulf Coast region of Texas and Louisiana. If no wells are available, surface geophysical methods can sometimes be used, depending on surface accessibility for placing electric or acoustic probes. During this time of oceans and deltas, as tectonic forces gently folded the bedrock of Illinois, a large basin was formed centered in the southeastern part of the state.
