How does the Eljen Prefabricated Composite Drainage System (EPCDS) differ from other drain products?
Eljen EPCDS is manufactured in panels that are completely prefabricated all ready covered with geotechnical drainage fabric to any height specified and any reasonable length. Other drainage products are either 4’x8′ panels or are in rolls of 4’x100′ and generally have a geotechnical filter fabric only on one side. Other drainage products bond the filter fabric to the cuspations while the Eljen EPCDS drain does not.
