Curb Inlet Protection


Curb inlet filters are designed to be placed in front of a curb inlet or opening to prevent the migration of silt into the storm drain system. They are used to reduce turbidity of downstream waters by eliminating silt build-up in storm drain systems through the curb inlets. The overflow capabilities eliminates potential flooding.


Big Red

The Big Red filter is a REUSABLE inlet protector that prevents sediment from leaving the jobsite during construction. There are no pockets to fill, no velcro bags, and no assembly is required. Simply place Big Red in front of the inlet, making sure it lays in the contour, and you are DONE!

Big Red Curb Inlet Protector Advantages:
  • easy to install
  • versatile for a variety of curb inlets
  • reusable and extremely easy to clean
  • made from 90% inert recycled materials

Simple installation translates into simple removal, cleanup, and reuse at the next project or phase. Maintenance is as easy as lifting the filter from the inlet, shaking off the mud, removing any sediment on the concrete, and putting it back in place. If it contains an excessive amount of sediment, simply wash out the filter in a vegetated area and Big Red will be as good as new.

All of these features and benefits combine to make Big Red curb inlet protector the perfect choice for any curb inlet application. Big Red is available in 7 1/2” diameter X 10’ long sections that weigh approximately 85 pounds. Custom sizes are also available upon request.


Filter Socks

Filter socks are a ready-to-use erosion and sediment filtration device filled with a proprietary blend of 100% recycled and biodegradable kiln-dried material. The outer mesh netting is photodegradable over an extended period of time as well. Installation can be accomplished without disturbing the soil surface, thereby reducing erosion. Filter socks are easy to move, will not be damaged by wind or aggressive rainfalls, and requires minimal staking. They allow water to flow through at a controlled rate, while separating and retaining sediment and pollutants to improve the downstream water quality. Filter socks provide money-saving advantages by reducing labor, equipment, replacement and disposal costs. In addition to inlet protection, they are effective perimeter devices that are approved for ditch check, slope interruption, and perimeter control applications.

Filter Socks Advantages:
  • low to the ground, allowing for easier access to the work site
  • staking is only required on steep slopes
  • lays on top of ground with no equipment needed
  • easy to move, shape and fit to site
  • reusable and requires minimal maintenance

GeoCurve

GeoCurve is a filter for curb inlets used to capture debris and sediment transported by stormwater runoff. The device is comprised of a filter media (woven monofilament filter fabric) affixed to the lower portion of a “C” shaped 12-gauge welded wire frame (2” X 4” openings) with an upper retention flange. It effectively filters stormwater, can easily be removed for maintenance and cleaning, and incorporates an overflow window for heavy storm events.

The device easily installs into the throat of the curb inlet eliminating any exposed elements that may pose hazard to traffic or pedestrians. The GeoCurve’s shape allows for collection inside the throat of the inlet capturing unsightly trash and sediment making for a more aesthetic solution. Incorporating a high-flow filter fabric and an overflow opening that will provide efficient filtering, the GeoCurve still allows for a high flow of water during heavy storm events. GeoCurve filter is easily maintained by removing the device and dumping the captured debris and sediment in a designated location. Once the accumulated debris has been removed, the unit can be reinstalled for continued service. The GeoCurve inlet filter has been hydraulically tested with excellent results. The device was able to handle flow rates of 350 gallons per minute without water backing up into the street.

GeoCurve Advantages:
  • does not cause flooding when it clogs with debris
  • sand bags not necessary to secure or weigh down unit
  • completely covers the opening of the inlet and is installed without protruding parts that could be a traffic, worker, or pedestrian hazard
  • is attached in a way that it can be easily removed
  • maximizes pollutant reduction
  • inexpensive maintenance
