SiltSoxx Alternative Staking Method Approved for Use

The Filtrexx Research, Technical, & Environmental Services Division recently conducted large scale ASTM testing (modified ASTM D6459) to evaluate alternative staking patterns for SiltSoxx that may be more efficient during installation. For years we have seen first-hand how staking behind SiltSoxx can be as effective as through SiltSoxx for sediment removal and capacity in many applications. The objective of the study was to determine performance thresholds for this alternative staking pattern. Results show equivalent performance for low-medium rainfall intensity/accumulation events between staking through SiltSoxx and staking behind SiltSoxx. Based on this new data, we have updated all applicable standard specifications (Sediment/Perimeter Control and Slope Interruption) to allow this new alternative staking pattern. This should allow for faster and less expensive installation of SiltSoxx in all sheet flow applications, thereby further reducing total cost of ownership (life cycle cost) for all applicable projects.
