Still Learning

A New Jersey developer has received a $763,500 fine for not controlling sediment runoff from a construction site. The developer had previously received 18 warnings. Properly used, silt fencing, turbidity curtains, and other geotextile products can prevent many of the conditions that lead to these hefty fines. Read about the developer's troubles in the Mt.

When Northern Roads Go South

Geogrids and geotextile filter fabric are being brought in to repair the recurring paving problems on Homer, Alaska's Skyline Drive. Mudholes, pitting and rutting are a few of the problems the construction team looks to solve. Read the article online. Learn more here.;

Support Systems

"Low bid" and "best bid" do not have to be antonymous concepts. In many situations, the construction and maintenance costs of a road may be reduced and its life extended when geogrids are selected as one of the construction materials.

Heavy Metal

For decades, the state of Oregon used mine tailings for road and rail beds, reservoir construction, residential driveway paving, and much more. Little was known about the long-term health and pollution problems that might be associated with the tailings, which contained traces of heavy metals such as arsenic and mercury. Today, the old mines are being cleaned and the contaminated soil encapsulated with geosynthetics and buried. Contaminated soils remain in the towns, though. Oregon is not alone. Soon, many cities may need to recover and safely rebury the mine tailings once thought to be safe. Read about Oregon's experience in the Register-Guard. Learn more here.;

35% Increase in 1st Quarter

Larry Washaw, AMCOL president and chief executive officer states that significant "growth in our Lining Technology, Building Materials and Oilfield Services Groups” is due to "high demand for our oil related services and a strong, early European construction market."

Seeking Distributor

geosynthetica underwriter is seeking North American distributor for conductive geotextile to use on geocomposites and GCLs to facilitate electrical liner integrity/leak location surveys on double lining systems with nonconductive geocomposite leak detection system (LDS) between geomembranes. No need to backfill LDS with water to perform effective surveys. Slopes can be surveyed. Contact Lara at gsa.

Keeping Costs Down

0, an independent news collective, reports that the Arrowhead Lakes Homeowners Association, Arizona, reminds its residents that proper dock and retaining wall maintenance translates to a healthy lake liner--and it prevents potentially huge repair costs if the lake's lining is damaged due to general homeowner negligence. Like many new developments, man-made lakes are central to the community's higher property value and higher quality of life. Neglected lakeshore walls and docks could lead to a cracking of the concrete cover over the liner in the critical zone where it contacts the shore. This is the sort of awareness that the Geosynthetics Risk Management and Loss Control Program is promoting throughout the insurance and construction industries. To read the article on the HOA discussions, please go to the "continued" link below.
