• <br />Amencan Excelsior's Curler ll olanMets were used <br />fo prowde a stable environment for seeds to grow. <br />while preventing excessive soil and seed loss <br />through wind and water erosion on the right-of- <br />ways along the Illinois Tollway. <br />excessive soil and seed loss through wind <br />and water erosion," says Mr. Bob Klatt, <br />Landscaping Coordinator for the Tollway <br />Authority. "It also allows the seeds to estab- <br />lish and germinate. Once that is done, the <br />olanket biodegrades and goes back into the <br />environment and the seed has a head start." <br />• The blankets combine a dense mat of curled <br />and seasoned Aspen wood excelsior with a <br />tough, photodegradable plastic mesh which <br />remains in place even on rough terrain. As <br />Curler fibers become wet, they expand. As <br />moisture is released, the Fibers contract. This <br />natural motion creates a digging effect, main- <br />taining superior soil adhesion. <br />The Illinois Tollway Authority has installed <br />roughly three million square feet of the blan- <br />kets on the project at a cost of less than four <br />percent of the total landscape and restoration <br />budget which, according to Mr. Klatt, "is very <br />economical for complete erosion control." <br />Although the Illinois Tollway Authority has a <br />longstanding relationship with Amencan <br />Excelsior, they have used other erosion con- <br />trol blankets in the past.
