Back in February of this year, we launched this newsletter with a commitment to keep you abreast of news and information you should know about our industry. As indicated by your feedback, it appears we are doing our job. Subscription requests grow each month and many of readers are using the products and methods described.
Even with that positive feedback, some changes are in the works. Over the next few months you will see changes in our website. There will be more detailed information on product usage techniques. Finding what you need will take fewer clicks. Linking with other valuable sources will expand. Please watch your inbox and our website for these changes. As always, if you would like to see an article on something special, feel free to email me at dellis@geoturf.com

EnviroGrid™ Cellular Confinement System
|
EnviroGrid™ Cellular Confinement System Expandable Envirogrid™ is a lightweight, expandable confinement system made from high-density polyethylene plastic (HDPE). It can help create an erosion barrier or structural foundation by applying strength by containment technology. Use on retaining walls, boat ramps, driveways, slope erosion, structural supports and foundations, shoreline protection and roadways. Three available cell sizes. Depths: 3", 4", 6" & 8" Standard sections are 10 cells wide and 29 cells long. Nonstandard configuration can be manufactured to meet project requirements.
The Envirogrid™ placed on a steep slope holds the fill material in place. Also, the cell walls slow the flow of water down the slope. This action reduces or eliminates the formation of rills which are a major cause of soil erosion. In addition, water trapped in the cells will seep down through the fill soil, which promotes deep root growth. Envirogrid™ may also be installed on slopes subject to wave action. With the geocells, small rip rap or rock that would normally be washed away can be used to control wave action erosion.

Geoturf Tubes are an ideal solution for dredged material management. They greatly reduce dewatering time and disposal costs, and provide opportunities for the beneficial reuse of dredged materials. Tubes can be used to dewater sediment dredged from channels, inlets, marinas, harbors, rivers, detention basins, ponds and lakes.
Geoturf Tubes are available in a number of standard sizes as well as custom lengths. The holding capacity of any one tube depends on the type of dredge material. The chart below provides guidelines when sizing a dewatering project.


Tubes provide a safe method of dewatering contaminated sludge material. Once dewatered, the “dry” fill material can be reused or disposed of more cost-effectively as a solid waste.

Erosion FYI
What Contributes
to Erosion?
|
Heavy rainfall, steep slopes, removal of most existing vegetation, and erodible soils result in higher soil losses from erosion.
|
|
| Lower rainfall amounts, flatter slopes, preserving existing vegetation, and less erodible soils result in lower soil losses from erosion. |
 |
Types of Erosion
Raindrop erosion occurs when drops hit the earth and breakdown soil structure. Slope runoff creates sheet erosion, which can lead to the formation of small rill channels and larger gullies.
Erosion of unprotected stream banks results from removing vegetation and higher flows, which are caused by uncontrolled runoff from construction sites. |
