Stabilizing Wet Soil with Lime Brings Amazing Results

PanzRule posted the information below on the ConstructionKnowledge Forum last week and I thought it was too good not to share further. I used lime on a fast-track factory project a few years ago with excellent results. We finished the project on time, which couldn’t have happened without the lime soil mixing.The experience shared by PansRule below should be read by everyone who has to work to control construction schedules and wet/frozen soils.

In conjunction with the snowfall we had what I would consider a cold winter. Now this is coming from a guy who spent the last 11 years working in an office who now was the acting site project superintendent, project manager and occassional equipment operator. So needless to say my opinion may be slightly skewed due to the time spent in the office becoming soft.

Because of the wet & frozen soil conditions throughout the winter and the owner’s need to maintain the project schedule soil modification was used. To be totally honest, I was skeptical of the process. I had never seen this process used and by the prices that I recieved for purchasing the material, I was petrified!

BoRit one year later

One year ago this week, the Environmental Protection Agency placed the BoRit asbestos site on its Superfund National Priority List, setting in motion a process that will have a long-term impact on the area.
Sites on the NPL have "known releases or threatened releases of hazardous substances, pollutants or contaminants," according to the EPA's Web site.
By placing the site on the NPL April 8, 2009, the EPA began efforts to remove immediate risks at the site and started a long-term analysis of it to determine a final solution for the asbestos contamination.
The EPA’s action to address immediate risks, termed the removal stage, began last spring. The removal action has been divided into three phases, two of which have been completed with plans for the third being prepared.
Phase I stabilized the stream banks of the Wissahickon Creek by placing geotextile fabric and erosion mats along the>Phase II, which began in September and wrapped up last month, concentrated on the area near. this and many more erosion articles
