Western Excelsior's Excel SD-3 Erosion Control Blanket (ECB) consists of a 100% Rocky Mountain Excelsior matrix stitched between two heavy-duty, synthetic nets. Excel SD-3 is manufactured to incorporate a heavier excelsior matrix, greater tensile strength, greater longevity and thickness than standard excelsior blankets. The Excel SD-3 ECB provides erosion control for a period of up to thirty months and serves as a mulching layer. Actual longevity depends on soil and climatic conditions. Available in a variety of roll sizes, Excel SD-3 provides reliable, economical erosion control, ideal for slope projects that would benefit from the long lasting performance and heavy duty construction. Excel SD-3 is also recommended as a long lasting, high performance, degradable liner for channel projects. Like all Western Excelsior products, Excel SD-3 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.
