Geotextile Tubes to Defend 7-Miles of Grand Isle Shore

0
The US Army Corps of Engineers (USACE) is entering into a $50 million agreement with the state of Louisiana to repair the Grand Isle storm-surge protection barriers. Governor Bobby Jindal signed the agreement on Thursday, April 2. The project is to be fast-tracked and will use geotextile tubes packed with sand to form the core flood defense measure along much of a seven mile stretch. The previous storm-surge defenses were destroyed by Hurricanes Katrina and Rita (2005) and Gustav and Ike (2008). The barrier system will be 13 feet high and will be composed of central, sand-filled, six-foot-diameter geotextile tubes with additional sand packed around them.

Raven Reports 3Q Results

0
Raven Industries released strong third quarter results on Wednesday. The Flow Controls Division continues to perform well while the Engineered Films Division (which includes Raven's geomembrane lines) saw 23 percent growth in third quarter sales. Raw material costs (including the often volatile resin market) pinched some profit, but overall volume was good and high demand in the oil and gas industry for pit and pond liners continued to be one of the company's signature successes.

Updated EVOH and Geosynthetics Brochure

0
Kuraray Americas EVAL EVOH layer has been proven to be an exceptional barrier to gases, including volatile organic compounds (VOCs). In geomembranes, EVOH layer greatly enhance the gas barrier performance of the membranes. (Geomembranes in general are engineered for liquid impermeability. Gas transmission rates can remain elevated; hence, the need for improved gas barrier performance.) Learn more about EVOH's role in this updated introduction to EVOH and Geosynthetics from Kuraray America (PDF).

ShoreMax® Soft Revetment Scour Protection Mat Supercharging Green Alternatives to Hard Armor

0
In recent large-scale channel testing by the American Association of State Highway Transportation Officials' National Transportation Product Evaluation Program (AASHTO-NTPEP), North American Green's new ShoreMax® Soft Revetment Scour Protection Mat pushed turf reinforcement mat (TRM) performance to a new level. As one of the newest additions to Tensar's North American Green erosion control line, the ShoreMax® Mat delivered unprecedented unvegetated results in NTPEP's ASTM channel testing, withstanding shear stresses up to 8.6 lbs/ft2 and velocities exceeding 19 ft/sec. Tested with a Vmax3® P550 TRM underlayment, the completely unvegetated ShoreMax system actually exceeded the level of performance provided by many fully vegetated TRMs.

$4B worth of wastewater projects under way in D.C.

The Blue Plains wastewater treatment plant in Washington, D.C., is starting a $4 billion project to meet new regulations and enhance water quality in the Chesapeake Bay. Nitrogen levels will be reduced and tunnels built to store peak water flows for later treatment. Cambi thermal hydrolysis will be used to "cook" wastewater sludge into upgraded biosolids to be used to generate energy for the plant. "This is about as green a project as you can get," said Dave Schwartz, of Camp, Dresser & McKee. Learn more here.;
