	On a residential construction site in eastern Oklahoma pockets of liquefaction occurred, after trenching for electrical lines completed. The pockets are approx. 8' x 8' and 5' x5' with a distance of 50' between them. Are there options to stabilize the soil i.e. through drainage or the addition of lime? The area in question is planned for hard scape only, a stone fire pit is to be build on top of a pocket. Though there are existing structures nearby. Any help is appreciated.

	add lime to the 'liquid' soil', mix it in well. Lime neutralizes the electrostatic forces that cause the colloid formation of water and clay particles. __________________ Keith E Bowers, PMP

	Thank you for the help. After proof rolling the area the questionable soil was removed. The fill mixed with lime was compacted. So far it seems to work. We will know more after the next rain. Again thank you for the replies
