Prefabricated Wall Drain System for Structures
The conventional method to reduce hydrostatic pressure behind vertical structures, such abutments and retaining walls, is to use coarse aggregate to capture and transmit incoming liquid. This method may be expensive depending upon the availability of the coarse aggregate. In addition, it may be difficult or unreliable to install a vertical soil drainage layer behind a structure. An alternative approach is to use prefabricated geocomposite drain (PGDs) to replace the coarse aggregate. The objectives of this work order are to evaluate material properties and design criteria, as well as to provide a cost comparison of a PGD system behind retaining structures. The final outcomes of this work order are material specification and design guidelines, which can assist the usage of PGDs in highway construction.
