Containment

Fiber Bragg Grating (FBG) sensors are incredibly versatile. They're used in tiny medical devices and on huge bridges. Often FBG and other types of fiber optic sensors are chosen when many measurements are needed over a long distance and the environment is harsh. A good example of this is the use of FOS in geosynthetic materials used to reinforce earthworks. Tom Graver of Micron Optics writes on this collaboration of technologies and how it could change geosynthetics.

Landfill engineering has advanced significantly over the past 35 years. Geosynthetic lining, capping, and final cover systems have had a lot to do with the tremendous success landfill operators...

The South African geosynthetics community continues to grow, in no small part due to relationships its participants have established with affiliated groups in construction and engineering. The latest...

The London Topic (Ontario, Canada) reports that PCB contaminated soil has been discovered outside the "vault" zones where reclamation work is on-going. The contaminated soils have been moved onto a polyethylene pad and covered with a PE membrane and geotextile fabric while officials meet and a public meeting is scheduled. Longer term storage and containment will be part of the site's soil cleanup. Learn more here.;

ASTM Committee D18 on Soil and Rock has announced work item WK38062, Revision of D6459 - 11, Standard Test Method for Determination of Rolled Erosion Control Product (RECP) Performance in Protecting Hillslopes from Rainfall-Induced Erosion. The balloted issue regards revising issues associated with Note 7 in the standard. Note 7 reads: "Distribution of rain drop size and intensity over the plot may affect results and needs to be evaluated on a case-specific basis." Learn more here.;

Geosynthetics 2009 is the largest geosynthetics industry event in North America.

HDR has performed reservoir analysis for the Rivanna Water and Sewer Authority in Virginia. During a public meeting, an HDR representative reported very favorable conditions at the reservoir site and that dredging could help maximize the site's capacity. The study estimated the reservoir's water storage volume at a minimum 1,247 million gallons. The estimated dredging volume totals 1.54 million cubic yards of sediment. Part of the presentation included a video showing how geotextile tubes are used for dewatering. Learn more here.;

A lawsuit filed by the Yakama Nation and Heart of America Northwest Research Center in Washington State. The low-level radiation in waste needs to be covered, the edge of the proposed cap it has been discovered would likely extend beyond the site's 100 leased acres. A new approach will be needed.

State Route 710, a freeway heavily used by commuters and trucks hauling goods from the nation's busiest port complex, runs 23 miles from Long Beach to an abrupt end just east of Los Angeles. From there, tens of thousands of vehicles a day spill onto Alhambra city streets to reach other freeways. The 4 1/2-mile gap between the end of the 710 and Interstate 210 in Pasadena is a startling deviation from the rule that freeways are king in California. Learn more here.;

The spread of COVID-19 around the world is directly impacting geosynthetic containment projects. A number of project delays are being reported, either related to available personnel/materials or to temporary...

Construction magazine--one of the numerous regional mags in ACP's stable--has posted an article on an erosion control project in Maryland's Chesapeake Bay area. The revetment work relied upon global positioning satellite (GPS) technology for accurate installation of materials, including a tricky geotextile placement. Learn more here.;

IFAI Expo Asia 2011 will be held 22-25 March 2011 at the new Marina Bay Sands Hotel and Exhibition Centre in Singapore, and is being organized to serve the rapidly growing specialty fabrics marketplace in the Asia-Pacific region. There is a tremendous output and consumption of specialty fabrics in the Asia-Pacific region. The current trade shows in India and China focus almost exclusively on the disposable nonwoven industry. IFAI Expo Asia 2011 will now become the first major event in the region that specifically targets as visitors the end-product fabricators who use all types of materials--woven, nonwoven, knit and composite textiles.

Environmentalists this week expressed fears that Venice would face an increased risk of flooding if plans to expand the Italian city’s port are allowed to go ahead. The city’s port authority wants to develop a huge facility for bulk carriers. Learn more here.;

Abstracts for Geo-Frontiers 2011 are due by 8 March 2010! Please keep this in mind during the coming week. Geo-Frontiers 2011 brings together the North American Geosynthetics Society (NAGS), the American Society of Civil Engineers (ASCE) Geo-Institute (GI) and the Industrial Fabrics Association International (IFAI).

Neighbors of Alby Quarry in Alton, Illinois are pleased to learn that the years of blasting they've endured may finally be at its end. A new proposal has suggested converting the quarry into a construction debris landfill. During a public meeting, the proposal was discussed. A clay liner with a geosynthetic barrier would be installed to secure the site. This might be the first instance in the US of the neighbors encouraging the construction of a landfill.

On May 28, SWANA's International Board of Directors approved the following statement concerning the recent report The Importance of Landfill Gas Capture and Utilization in the U.S. After review by the International Board of Directors and Technical Divisions, SWANA concludes that this report presents a valid representation of the state-of-the-art of landfill gas capture and recovery as practiced in the U.S.

Canada's Daily Observer reports on the incorporation of geotextile tubes for sewage dewatering operations, and about the difficult path to getting this simple idea accepted. Many officials apparently have been concerned that the technology's function is too easy to understand to be believed effective. But the use of geotextiles tubes for separating solids is finally getting its day and correcting many of Ontario's sewage handling issues. Learn more here.;

Arizona’s breccia pipes contain some of the world’s purest uranium. There is a significant amount of interest in establishing mining operations to explore and extract it. That interest cannot currently be pursued due to a federal segregation, or time-out, imposed in 2009. But, change may be in the forecast because the segregation expires in July. Learn more here.;
