Many Low Impact Development Practices were used, including bioretention, bioswales, vegetated structural roadway shoulders, permeable pavers and rainwater harvesting and reuse....
WHY THESE PRODUCTS?
One of the most important tools in preventing stormwater pollution from a construction site is the Stabilized Construction Exit (SCE), also referred as Stabilized Construction Access, Construction Exit, Exit, Rock Exit, etc… These can be made of various materials, the most common being rock. However, a new product called FODS is shaping up to be a great alternative to rock exits.
FODS: TRACK OUT MATS
Why Do We Recommend This Product?
“Virtually all new projects, and most redevelopments, constructed today must account for the quantity and quality of the water leaving the site once construction is complete, and forever after. To accomplish this, Construction EcoServices offers turnkey compliance services during construction activity, erosion control solutions for slopes and channels, post-construction compliance services for stormwater management systems for detention and stormwater quality treatment.”

FODS – The Mud Stops Here
The FODS Trackout Control Mat was created as a simple solution to a common problem – construction companies were spending valuable time and money on ineffective, conventional trackout solutions like aggregate or wheel washes which still resulted in job site fines. Developed by an experienced team of contractors and engineers, the FODS Trackout Control Mats is the only durable, cost-saving, and environmentally friendly trackout solution available. FODS Trackout Control Mat was created…TO STOP MUD IN ITS TRACKS!
WHAT IS FODS?
FODS stands for Foreign Object Debris System.
The purpose and design of the FODS Trackout Control Mats are to effectively remove sediment from vehicle tires as they exit a disturbed land area onto a paved street.
HOW DOES FODS WORK?
The FODS Trackout Control Mats help sediment control by deforming the tire, spreading the tire lugs apart, depositing the dirt, rock, mud, or other sediment onto the mat. Tire lugs and/or treads will make contact differently with the pyramids’ various surfaces. As the tires roll across the mat, the pyramids will scrape, clean, deform, and wipe debris from the tires. Once the tires reach the street, they will be virtually clean from any material.
WHAT ARE THE DIMENSIONS OF A SINGLE FODS MAT?
FODS mats are 12′ wide x 7′ long and are 430lbs. The mats are easily stackable and will not exceed the width requirements for highway transportation.
WHERE ARE GOOD PLACES TO INSTALL FODS?
Construction Sites, Airports, State and Local Governments, Agriculture, Forestry Access road, Oil/Gas, Energy, Telecommunication, and Mining are all in need of the FODS Trackout Control System every day.
HOW MUCH WEIGHT CAN A FODS MAT WITHSTAND?
FODS Trackout Control Mats can handle nearly limitless weight. Due to its construction from Ultra-high-molecular-weight polyethylene (UHMWPE) each pyramid on the FODS mat has a crush rating of over 50,000lbs. The smallest passenger vehicle tire will disburse it weight across a minimum of four pyramids at all times and the larger tires of a commercial vehicles with a rating of HS-20 will disburse their weight over a minimum of eight pyramids per tire. FODS has proven performance with over 250,000lbs. on a single mat.
HOW DO I INSTALL FODS?
The FODS mats are transported to the construction site on a large truck or trailer. The mats will then be off loaded into place with a forklift or truck mounted boom or jib crane on the in situ soils. No excavation or disturbance of the existing soil is necessary. Once the mats are correctly situated in place, soil anchors can be installed through the mats to hold them into place. The Cable Earth Anchor or Form Stake can be manually torqued through pre-drilled holes in the FODS mat. We recommend providing a minimum of two anchors per mat.
HOW CAN A FODS MAT BE CLEANED?
We recommend using a Skid-steer broom attachment or a FODS Shovel (specifically designed to scoop between pyramids). Other options include a Street Sweeper (requires adjusted bristle head), Pressure Washer (must have ability to contain water), or a Water Truck (must have ability to contain water).
FODS BEHIND THE SCENES
STANDARD ROCK EXITS
About Rock Exits
Maintaining a construction exit consist of “turning” the rock and or simply adding additional rock which we call a refresh. Either one will be required once the rock exit has accumulated a substantial amount of sediment that causes tracking to occur onto the street as depicted above.
If your site does not meet the spec and or the amount of rock is minimal, odds are your site might be visited or you may need additional rock more often. Thus increasing what you thought was a cheaper price for an exit.
Ask the questions – what size will my SCE be? What size rock do you use? How much rock will you lay down? Be careful of someone giving square yardage, this can be deceiving. How deep will the SCE be and do you lay a fabric down first? So goes the saying, Buyer Be Ware.
If you have any questions regarding Stabilized Construction Exits or requirements for staying in compliance, contact us. We are here to help.
- Length shall not be less than 50 feet.
- Thickness shall not be less than 8 inches.
- Width shall not be less than the full width of all points of ingress or egress. (CES always does 25 feet wide unless told or instructed otherwise).
- Stabilized construction exits shall be maintained free of sediment for the duration of the project (this to prevent tracking on the street
