Why does the loose or not glued fabric on the Eljen EPCDS drain not get compressed down into the channels of the cuspate core during the backfilling of the soil and reduce the flow of the groundwater?
Due to the close spacing of the Eljen core’s cuspations, there is very little pressure on the fabric. Natural soil bridging from one cuspation to the other occurs. The soil that is backfilled bridges across the short distance of the cuspations. Therefore, the fabric is not pressed into the channels and there is no reduction in the flow. Eljen drainage fabric is semi-ridged adding to the strength.
