A common feature of civil engineering design is the ""french drain"", a trench intended to intercept and collect groundwater and transfer it laterally to a sump. The environmental marketplace ahs created a larger demand for these drains for the purpose of ...

This paper presents a construction method, the bio-polymer slurry drainage trench, which is a modification of the well known slurry trench method which uses biodegradable trenching slurry to temporarily support the trench walls and control trench width.

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 ...
