MSE wall drainage alternatives
The use of mechanically stabilised earth (MSE) walls has dramatically increased in the last few years, resulting in unparalleled opportunities for the application of geosynthetics. However, with these opportunities has come the challenge to continue to design and build MSE walls using sound engineering principles. It must be supposed that many walls of different complexities are built every year with little or no geotechnical design. No other aspect of MSE wall design is overlooked as often as hydrologic design. Obviously, its impact on the performance of MSE walls is underestimated. A recent study by the Geosynthetic Institute attributed a majority of the reported MSE wall failures to a lack of drainage and filtration. The authors of this article feel that by discussing the various drainage and filtration alternatives and their impact on the overall cost of the wall such problems can be minimised. A comprehensive drainage and filtration plan should address the following: Drainage at the top of the wall, including an impervious layer if necessary; drainage and filtration at the back; and drainage and filtration at the front of the wall.
