INSTALLATION OF A DEEP DRAINAGE TRENCH BY THE BIO-POLYMER SLURRY DRAIN TECHNIQUE (1988)

This paper presents a bio-polymer slurry used, instead of bentonite slurry to temporarily to support the trench walls without structural bracing. Upon completion of backfilling, the slurry in the trench was chemically reduced to water and simple sugars to acitvate the drain. The entire trenching and backfilling operation, including well placement, was completed in about two weeks
