Cellular Confinement Systems (CCS)—also known as geocells—are widely used in construction for erosion control, soil stabilization on flat ground and steep slopes, channel protection, and structural reinforcement for load support and earth retention. Typical cellular confinement systems are made with ultrasonically welded high-density polyethylene (HDPE) strips or Novel Polymeric Alloy (NPA)—and expanded on-site to form a honeycomb-like structure—and filled with sand, soil, rock, gravel or concrete.

Getting Tough on Turbidity

Getting Tough on Turbidity

Meeting federal antipollution requirements to ensure clean water has become a routine part of erosion control work. For projects that take place around waterways, that often means the use of turbidity curtains or coffer dams. In business since 2005, Tampa Bay Marine in Riverview, FL, specializes in the installation and

In rural Beaufort County, NC, a new bridge was being built over the Norfolk Southern Railway to replace an aging structure. “The project consisted of raising the elevation and widening the bridge,” explains Staci Smith, regional engineer for ACF Environmental. “This led to the need to steepen the adjacent slopes

Beyond Riprap

Beyond Riprap

The city of Doral, FL, is facing a two-pronged problem in an extensive drainage canal system. Over many decades, small wave action has gradually eaten away at the canal banks and threatened the integrity of guardrails along a couple of adjacent roadways. Not to be overlooked is the damage the

The Coffin Golf Club in Indianapolis runs along the White River. Jim Blazek, a principal of D2 Land and Water Resource Inc., explains the problems faced when the river occasionally floods. “The river floods the course, and there is some erosion due to the floodwater coming up and flowing alongside

Blanket Protection When Water Threatens

Blanket Protection When Water Threatens

It’s usually a smart decision to work with nature when you need to overcome the challenges she presents. When you’re working to revegetate an area, you just can’t always assume nature is willing to work with you. Erosion control blankets and turf reinforcement mats can be the solution in these

Channel Protection Measures

Channel Protection Measures

Stormwater runoff, consisting of moving water both during and in the aftermath of a downpour, may be managed (or mismanaged) in a number of ways. As described in the Alabama Handbook for Erosion Control, Sediment Control and Stormwater Management , “In an undeveloped area, stormwater runoff is managed by nature

Building Business by Building Retaining Walls

In the tight-margin business of grading and excavation it never hurts to have a competitive edge-a special niche in the marketplace that allows you to leverage your earthmoving talents, crews, and equipment into more profits. Using new or existing techniques and materials to build unconventional retaining walls might offer one

Choices in Channel Protection

Rushing waters eating away at road embankments or undermining bridge pillars is not a pretty sight. Preventing these disasters is often the job of an erosion control contractor, and the availability and variety of tools for the job are incredible. If you have a bank stabilization project, how do you

Geogrids: Stability Against the Odds

“Geogrids are plastics formed into a very open gridlike configuration,” writes Robert Koerner, an authority on geosynthetics. “That is to say, they have large apertures. Geogrids are stretched in one or two directions.”

Geogrids’ strength gives them the ability to be used for base stabilization, for slope reinforcement, to reinforce

Geocellular System Replaces Aging Broadmoor Road Retaining Wall

At first it seemed like mission impossible: Build a 30-ft.-high structure across a 185-ft.-wide, steep, wooded ravine to replace an aging steel sheet-pile retaining wall. Minimize the size of the footprint to reduce impact on the stream flowing through the ravine. Make the structure green-as in grass or other vegetation
