Curb Inlet Protection Products for Construction

Curb inlet protection products trap sediment and slow the velocity of runoff.

Every site needs different solutions. We offer high visibility products, specialty sizes and environmentally friendly solutions.

Dandy Curb®

Orange cylindrical tube with attached aggregate pouch

Inlet protection for curb inlets and median inlets without grates

Filters sediment before it flows into inlet

Features

High visibility international orange

Conforms to shape of the curb

Built-in overflow design

Sized to fit most curb inlets

Easy to install and maintain

Applications

Curb inlet protection

The Dandy Curb® is designed for curb inlets and median inlets without grates. The design features a tube that conforms to the inlet’s opening and an attached aggregate pouch to weight the device in place.

The porous cylindrical tube made from high visibility orange monofilament geotextile fabric. This high performance geotextile fabric is highly visible and super-strong.

The Dandy Curb® filters runoff as stormwater flows into the drain. The inlet protection device captures silt, sediment and suspended solids then slowly releases the filtered water into the storm system.

Place the Dandy Curb on the ground with the aggregate pouching facing towards the street.
Open the Dandy Curb’s velcro access pouch.
If using oil absorbents, place the sock in the pouch.
Fill the pouch with aggregate to the point that it is filled but not overflowing. The pouch should create a seal between the Dandy Curb and should keep the product in place during a rain event.
Reseal the pouch and place the Dandy Curb against the curb inlet. There should be an event amount of overhand on both sides of the inlet’s opening.

Inspect the Dandy Curb after major rain events. and remove any sediment that has built up on or near the Dandy Curb.

The Dandy Curb should have one foot of overhang on both sides of the grate. Measure your inlet and add two-feet to order the right size Dandy Curb.

Dandy Curb Sack®

Curb and gutter inlet protection

Combines Dandy Curb and Dandy Sack

Captures suspended solids while stormwater slowly filters through sack

Features

High visibility orange monofilament geotextile fabric

Two-part design protects gutters and hangs below grates

Easy to install and inspect

Made in America

Applications

Curb and gutter inlet protection

The Dandy Curb Sack® is our only two-part curb and gutter inlet protection solution. The unique device protects gutter openings to prevent debris from entering the storm system, while filtering sediment laden runoff while it flows into the gutter.

Like all Dandy products, the Dandy Curb Sack® is manufactured in the USA from durable, high-visibility orange monofilament fabric that is built-to-last.

The Dandy Curb Sack is made to fit most curb and gutter sizes. Custom orders are always available if in-stock sizes don’t meet your project’s needs.

Remove the grate from the inlet and stand it on one end.

Place the grate into the Dandy Curb Sack® so that the grate is below the two top straps and above the lower straps.

Position the top straps in place so that they are on top of the grate.

Using the top straps, carefully insert the unit into the frame.

Secure the cylindrical curb portion against the curb to prevent debris from entering the inlet.

After each storm event remove accumulated sediment and debris from the Dandy Curb Sack®.

Regularly inspect the below grate sack. If the containment area is more than 1/3 full of sediment, the device must be emptied.

To empty the unit, use the lifting straps to lift the below grate sack from the inlet and remove the grate.

Compost Filter Silt Sock for Curb Inlet Protection

Wattled filled with aged and shredded wood chips

Heavy duty multifilament netting

Multi-purpose erosion control product

Features

Heavy wattle stays in place

Dynamic sizing with wattles up to 200-feet long

Economical

Applications

Inlet protection

Check dam

Perimeter control

Slope interruption

Compost Filter Silt Sock is a versatile erosion control product that can be used for inlet protection and sediment control.

Silt sock is filled with 100% recycled wood chips and encased in a photodegradable netting. The wood chips filter sediment laden runoff after water passes through the tightly woven netting.

The multifilament polypropylene, photodegradable mesh has an 1/8” opening pore size. The small pores allow runoff to filter through the net while retaining the filter media within the silt sock.

8-inch and 12-inch diameter Compost Filter Silt Sock will suit most curb inlet protection applications. Always consult the project engineer and/or construction plans for recommended products and sizes.

Silt Sock is manufactured in 10-foot wattles and continuous pallets up to 200-feet. If you are working from a continuous pallet of Compost Filter Silt Sock, cut pieces off of the continuous pallet to the desired length. Tie off the end of the Silt Sock wattle with Tie Wire.

Install Compost Filter Sock in front of the inlet’s mouth.

The weight of the filter sock should keep the wattle in place. For additional protection, place filled sand bags at either end of the Compost Filter Silt Sock.

Maintenance will vary per application.

For curb inlet protection applications, inspect the Compost Filter Silt Sock after major rain events and periodically in between rain events.

If the filter sock has been punctured and the filter material is flowing out of the wattle, repair or replace the Compost Filter Sock with a new wattle.

If the filter sock has been punctured but is not compromised, replacement may not be necessary. Monitor the Compost Filter Silt Sock carefully for further damage.

Compost Filter Silt Sock filter material can remain on site after final closeout. Cut the netting and spread the filter material across the ground away from the inlets. Remove the netting and dispose of it properly.

CFS for Inlet Protection

Excelsior Log | Curlex® Sediment Log

Patented Curlex® filled log with degradable netting

Curb inlet protection for storm drains up to 8-feet

Captures suspended solids before pollutants contaminate stormwater system

Features

Lightweight

Environmentally friendly

Economical

Easy to install

Applications

Curb inlet protection

Check Dam

Slope interrupter

The Curlex® Sediment Log, also known as the Excelsior Log, is filled with Curlex® fibers and wrapped in degradable net.

Curlex® fibers are derived from Great Lakes Aspen wood fibers, then cleaned curled and barbed to create an interlocking matrix. The Sediment Log’s wood fibers filter runoff and slow the velocity of water as it enters the storm drain.

The Curlex® Sediment Log’s degradable containment net has an open weave that allows runoff to easily filter through the fibers. This design ensures the wattle is lightweight, flexible and porous.

In addition to storm drain protection, the Excelsior Log is specified for check dams, slope interruption and perimeter control.

Place the Curlex® Sediment Log in front of the storm drain opening. Some applications may require sandbags to weight the Excelsior Log in place.

Inspect the Curlex® Sediment Log after rain events. If is has been displaced, return the log to the curb inlet.

If the Excelsior Log has significant sediment build up, replace the wattle with a new one.
