Both ends should extend at least 8 feet upslope at 45° to the
main fence alignment.
Install downslope of all disturbances in existing ground and parallel to
existing contours. Install silt fence on level grade.
A temporary barrier of curved geotextile (filter fabric) with sand tubes
attached to supporting t-posts to remove sediment from runoff below
disturbed areas.
Controls sheet flow runoff from small disturbed areas where the
discharge is to a stable area.
• Do not use in areas of concentrated flow (e.g. channels, swales,
erosion gullies, across pipe outfalls, or as inlet protection, etc.).
• Heavy vegetation should be removed prior to installation. The
fence can be used on rocky slopes if enough preparation is made
to ensure good contact of the sand tube with the underlying soil
along its entire length.
• Trenchless Curved Silt Fence should not be installed on
uncompacted fills or in extremely loose soils (e.g. sandy loam)
since this will likely result in undermining of the fence.
• Traffic shall not be permitted to cross the sand tubes.
• Should be installed at least 8 feet from the toe of fill slopes.
• Accumulated sediment shall be removed when it reaches 11" high
on T-posts. There are sediment removal lines on the studded T-post
stakes for easy identification.
• The Trenchless Curved Silt Fence shall be inspected weekly and after
each runoff event. Damaged sections shall be repaired or replaced
within 24 hours of inspection.
• Perform all preventive and remedial maintenance work — including
clean-out, repair & replacement — immediately following inspection.
• Maintenance and inspection must be continued until the site is
permanently stabilized.
• Upon stabilization of the area, the fabric, sand tubes, T-posts, stakes,
bottom plates, angled top brackets and pins shall be removed. Fabric
shall be properly disposed. Sand tubes, T-posts, stakes, bottom
plates, angled top brackets and pins in good working condition can
be reused on future installations.
