Geosynthetics for Roadway Construction

Geosynthetics for Roadway Construction

Ever since the Romans used palm fronds and other plant fiber matting to reinforce the sub-bases of their famous roads, fabrics have been used to improve road longevity and performance. Modern road construction methods rely on a family of materials called geosynthetics to achieve the same results. But these more sophisticated materials can

In Hydroseeding, Weather Matters (A Lot)

Weather can be a hydroseeding contractor’s friend or foe. It can make a job much easier or much more difficult. It played a role in each of the following varied projects done by leading hydroseeding companies across the country.

Maintaining Storage Tanks

Maintaining Storage Tanks

An integral ingredient in maintaining the health of a water supply tank is a good inspection according to tank manufacturers and consultants. In the words of George Mead, municipal sales director with Tank Connection in Parsons, KS, “Nothing fabricated and installed will continue to operate without inspections.”

Some states have created regulations

Transforming Landfills Into Resources

Transforming Landfills Into Resources

A landfill can be like a baby: It is helpless to care for itself; while it’s growing, it eats all day; at night when resting, it must be protected from the elements; and it belches constantly. If you’re lucky, it won’t stir up much fuss. If you’re not lucky, the neighbors

Retaining Walls to Change Land Surfaces

Retaining Walls to Change Land Surfaces

Retaining walls have become the modern-day structures of choice for us to manipulate the surfaces on which we choose to build our lives. From creating more buildable space on a site, to helping stabilize bridges, they are ubiquitous workhorses that are often easily overlooked. But sometimes they take their inspiration

Modern Scrapers—A Variety of Capabilities

Modern Scrapers—A Variety of Capabilities

When it comes to volumes of dirt moved, the sky is the limit for scrapers, notes Shane Kroeker, vice president of marketing for K-Tec Earthmovers. And, for moving earth on a job site, the scraper serves as a versatile piece of equipment, offering the ability to move a wide range of

Smart Irrigation Reduces Nitrogen Leaching

Smart Irrigation Reduces Nitrogen Leaching

While nitrogen is critical for agricultural production, too much nitrogen can negatively affect health and the environment. Ironically, excess nitrogen can even produce a harmful effect on crop yield, as well as native species and biodiversity.

A report from the Agricultural Sustainability Institute at the University of California, Davis, published by

An Approach for Communities to Assess Stormwater Application and Detention Requirements for Overall Watershed Health

An Approach for Communities to Assess Stormwater Application and Detention Requirements for Overall Watershed Health

Communities, especially those with limited resources, face many issues when trying to protect their local watersheds through the use of stormwater policies. Stormwater policies that are imposed on new development have the ability to enhance a community’s overall watershed health (Ferguson 1998). However, past requirements often relate only to large

Tiny, Long-Distance Travelers

Tiny, Long-Distance Travelers

We’ve written in Erosion Control magazine for years about the problem of airborne dust, and even the ways in which distant events—a sandstorm in the Sahara Desert, say—can deposit sediment particles thousands of miles away. A new study shows that the long-distance air-quality problem might be more widespread than previously
