Why is the claim that bonding the fabric to the cuspations of the core will prevent the fabric from closing off the channel of the core during backfilling, not correct?
Because of the wide spacing of the cuspations in many of the other drainage products, the bridging of the soil does not occur as it does with the Eljen EPCDS drain. The pressure of the backfill on the fabric causes the hot melt adhesive that held the filter fabric taut before backfilling, to elongate into the cusps. In some cases the adhesive is biodegradable, allowing the filter fabric to sag into the cuspations in the core.
