Western Excelsior's Excel S-1 Erosion Control Blanket (ECB) consists of a 100% Rocky Mountain Excelsior matrix stitched to a single net (top). Excel S-1 is available with photodegradable, synthetic netting (Regular); rapid photodegradable, synthetic netting (Rapid-Go) or all natural, biodegradable netting (All Natural). Excel S-1 ECBs are also available in natural or dyed green colors.The Excel S-1 ECB provides erosion control for a period of up to eighteen months (45 - 90 days as Rapid Go style) and serves as a mulching layer. Actual longevity depends on soil and climatic conditions. Available in a variety of roll sizes, Excel S-1 provides reliable, economical erosion control, ideal for slope projects that would benefit from greater erosion protection and improved mulching. Excel S-1 is also recommended as a degradable liner for low gradient/low risk channel pr ojects. Like all Western Excelsior products, Excel S-1 is made in the USA and yields LEED credits for the end user. In addition to a complete suite of standard documentation, detailed information on the advantages and properties of the product are provided below.
