Written by: Cory Schneider, Business Development Manager When contaminated material such as landfill waste or contaminated soil is encountered, there are typically two options available—removal of the material or placing a “cap” over it. In most cases, capping is the easier and more cost-effective of the two options. Caps serve to isolate the contaminated material, preventing people and wildlife from coming into contact with it. Factors Influencing Landfill Cap Design Landfill cap design for any particular site depends on many factors, including the type and quantity of contaminants, size of site, amount of rainfall, and future use of the area. It can consist of one or several of the following: asphalt or concrete, vegetative layer, drainage layer, and/or an impervious layer (geomembrane or compacted clay). Preventing Slope Erosion with Advanced Geosynthetic Technology When using vegetative covers, especially in sloped areas, one of the best ways to prevent long-term erosion of the cap is to confine the topsoil component using geosynthetics like the GEOWEB Soil Stabilization System (geocells). The GEOWEB Geocells, which are three-dimensional ultrasonically welded strips of high-density polyethylene (HDPE), create small pockets to hold soil in place. By doing so, the system prevents erosion or sloughing when the soil… Read more »

Federal Railroad Administration (FRA) Announces $1.1 Billion Available in the Railroad Crossing Elimination (RCE) Grant Program
The inaugural Railroad Crossing Elimination (RCE) grant program was designed to eliminate or improve roadway and railroad at-grade crossings, with the goal of making roads/rails safer while improving commute times for citizens. According to the U.S. Department of Transportation website, “this program provides funding for highway-rail or pathway-rail grade crossing improvement projects that focus on improving the safety and mobility of people and goods.” The grant program helps fund projects that involve: repairing grade separations, relocating tracks, upgrading or improving protective devices, signals, or signs, maintaining at-grade crossings, and more. With safety as the top priority for the DOT, repairing and maintaining high-impact areas is critical so the potential for collisions or blockages can be prevented. Applications for funding are due no later than 11:59 p.m. EST, September 23, 2024. Visit USDOT website for more information and to apply for funding >> The GEOWEB® System stabilizes high-impact and crossing areas safely and quickly, limiting track downtime. Areas subjected to heavy stresses at bridge approaches, diamonds, turn-outs, and crossings create the highest maintenance and safety liabilities for operations. The GEOWEB Soil Stabilization System (Geocells) is effective in reducing maintenance in these high impact areas. The GEOWEB 3D Soil Confinement System has been… Read more »
