Liner Repair Using an Engineered Bentonite/Aggregate Composite

摘要

Even in the "Land of 10,000 Lakes," soil conditions are not always conducive to holding water when trying to construct a lake or pond. This was the case for the Waterford townhome development in Rochester, Minnesota. The on-site soils contained a high percentage of sand, so the decision was made to utilize a high-density polyethylene (HDPE) synthetic geomem-brane liner in the construction of the basin at the center of the development. The liner was installed in 1994 and served well in keeping the 2.6-acre "lake" at the designed level for 15 years.
