Inlet Pro™ Sediment Bag
Inlet Pro™ Sediment Bags are an important part of standard Best Management Practices (BMPs) that should always be implemented to reduce surface water pollution from construction stormwater runoff. They are specifically designed to help retain the sediment and debris that can become dislodged and suspended in flows during rain events; utilizing this form of inlet protection can reduce the potential impacts of sedimentation.
Inlet Pro™ Sediment Bags are:
- Cost effective
- Easy to maintain
- Offered in different sizes and flow rates
- Reusable
- Required in many SWPPPs
- Available with foam/geotextile deflector for curb combination inlets
Sewing
All seams are produced using a double needle lock stitch with high strength, weather resistant nylon thread. The webbing terminations are also stitched using the same nylon thread in a box-x pattern.
Webbing
The 1” reinforcement webbing for the sack and optional center expansion restraint is woven using high strength, Hi-Vis orange polyester filaments/yarns to meet a nominal break strength of 3,200 lbs (14.25 kN).
Sizes
Inlet Pro™ Sediment Bags are available in multiple sizes to fit nearly any square or rectangular frame and grate; there is also an optional foam/geotextile deflector for use with curb/grate combination type inlets.
Durability
The high performance geotextile, used in conjunction with industry standard geosynthetic seaming techniques, produces a bag capable of holding 800-1,200 lbs (365-545 kg) of sediment, based on the dimensions of the bag.
Geotextile
Inlet Pro™ Sediment Bags are manufactured from a geotextile fabric consisting of polypropylene filaments/yarns that are woven into a stable, durable network such that the filaments/yarns retain their relative position. The geotextile fabric is non-biodegradable, resistant to most common soil chemicals, acids or alkali, and is manufactured to meet the minimum average roll values (MARVs) listed in the following table:
