Cotton-based hydraulic erosion control
North American Green introduced HydraCM Cotton Bonded Fiber Matrix, the mid-level product in its HydraMatriCx line of cotton-fiber, hydraulic erosion control products. HydraCM, developed in cooperation with the U.S. Department of Agriculture and Cotton Incorporated, contains a proprietary blend of tackifiers to provide erosion control and facilitate vegetation establishment on medium-length, moderate-to-steep slopes. According to the company, the product is cost effective because a larger area of coverage can be obtained per tank load, in comparison with mulches that require an increased water-to-mulch ratio. HydraCM and all HydraMatriCx products are made from straw and from cotton obtained from cotton ginning byproducts. Benefits associated with cotton include absorbency to hold moisture and promote seed-to-soil contact for germination; porosity for seedlings to push through with less resistance; and biodegradability. Other products in the HydraMatriCx series include HydraCX2 for use on steeper slope applications; and GeoSkin, for mild to moderate slopes.

Transportation technical reference
The Highway Innovative Technology Evaluation Center (HITEC) released a report and technical reference about Geopier Foundation Company’s Rammed Aggregate Pier construction, including design, performance, and applications details. The HITEC evaluation report represents a five-year-long research effort by panel experts from the Federal Highway Administration, state departments of transportation, geotechnical consulting firms, and academics. The panel reviewed and evaluated all research performed on the Geopier system, as well as specific design approaches. Additional laboratory and field research included instrumented demonstration projects. The final report outlines successful design and performance of the Geopier system as it pertains to transportation applications.

Robotic total station offers 3-D modeling capability
Topcon Positioning Systems, Inc., introduced the IS robotic total station with 3-D modeling capabilities. Features include IntelligentScan, which automatically recognizes distinctive features within the image field of view; ImageDrive, which allows an operator to operate visually from the image display; and I-Control, which allows an operator to connect to the IS via its IP address and take complete control from a personal computer at a remote location or from its WiFi-equipped FC-2200 field controller. The Topcon IS has a 20-points-per-second scan rate and can scan points as far as 2000 meters, the company says. Additionally, an integrated, dual digital camera imaging technology captures images with wide angle 4x and telephoto 30x optical zoom capabilities.

Biodegradable wattle replaces silt fence
RoLanka International, Inc.’s new Super-Wattle is made of coconut fiber (coir) and features one closely woven coir apron on the upstream side that prevents runoff from flowing under the wattle. The Super-Wattle is held in place by metal staples driven through the apron, which avoids the time and labor required to dig an anchor trench and to drive wooden stakes through the wattle to hold in it place. The wattle can be installed along slope contours to shorten slope length, reducing runoff velocity, and to trap sediment. It can also be installed at the base of slopes and around the perimeter of construction sites as an alternative to silt fence.

Pre-engineered system for fence-ready retaining walls
Strata Systems, Inc., offers Sleeve-It, a foundation system that uses traditional cantilever technology for anchoring perimeter fences and guards to mortarless block retaining walls. The Sleeve-It System was added to the company’s product line when Strata acquired Advanced Hardscape Solutions, LLC in mid-2007. The patent-pending Sleeve-it system is an extended family of products that includes steel-reinforced fence post integration systems. According to Strata Systems, Sleeve-It meets all code requirements for fences and guards as prescribed by Section 1607.7.1 of the IBC code. As an integrated system, Sleeve-It eliminates the 3-foot buffer zone mandated between fence posts and foundation (required when post-holes are bored after retaining wall construction is completed).
